2012 Baseball Draft: College Prospects 1-5
As I stated with the high school prospects, I have not seen every player in my top 100 lists. I haven't seen any of them in person. I have seen several of them multiple times on TV though. I have not seen a full game of Roache's, only edited highlights, but I have a good feel for the player that he is. I have a link to a video for each player so you can see what I am seeing for these five. I hope to see more of these guys throughout the upcoming college season and I'll let you know what I see. Without further ado, here is the first five.
Deven Marrero, SS, Arizona State
Marrero is the top college shortstop in this years' draft passing predecessor Kenny Diekroger. At 6'1", 175 he shouldn't outgrow the position. Defensively he is very capable at the position and looks to be a well above average defender. He has a strong arm, quick feet and very good range. He has soft hands and can turn the double play very well. He even played 2B well in one game I watched and he showed quick feet there as well. He is not a fast player, probably average or a tick above but has the athleticism it takes to stay at a demanding defensive position.
At the plate, he has very good contact ability. He tends to be aggressive at the plate and doesn't exhibit the patience that could improve his pitch selection. When he makes contact he hits the ball well. He won't hit a ton of homers, maybe in the 10-15 range but he isn't a slap hitter and should hit more than his fair share of 2B.
Overall, he is an above average defensive shortstop with the potential to have an above average bat for the position as well. Historically, he is a lock to be a major leaguer and with the skills he possesses, he should be a very good one. He is a safe pick and could go as early as the 1st overall pick or slide to the lower half of the top 10 but it would take a very poor season to see him slide more than that.
Kevin Gausman, RHP, Louisiana State
Gausman was looked at as one of the better arm in the 2010 draft but he never gained anything on his secondary pitches that spring and he slid to the 6th round. He opted to go to LSU. Gausman is very much a work in progress. He is a draft eligible sophomore from Colorado, so he hasn't logged the innings that many college pitchers have.
He is a long and lean at 6'4", 175 and needs to add strength to become a great player. On the mound, he is poised and looks like he belongs. He uses his size and arm angle to work down in the zone. He has mid to upper 90's velocity from a clean, easy delivery. It shows good life tailing down and in to righties. That kind of power arm is not easy to find. The fact he could add 15-20 LBS to his wide shoulders makes me believe he could be a workhorse with dominant stuff at the next level.
His secondary pitches are impressive and flash plus-plus potential. That being said, they are inconsistent. His breaking ball looks almost unhittable sometimes and others it flattens out and gets hit. His changeup has a hard fade to it and can make hitters look silly but his command needs work. He usually is around the plate and isn't the kind of guy who doesn't know where it's going. He is refining his ability and it shows.
Gausman is a rare talent but he isn't a typical college pitcher because he is as inconsistent as a high school pitcher at times. That is the advantage of getting him as a sophomore. Considering how well he held up against SEC talent last year shows his potential. I hope he gains consistency this spring and improves his secondary pitches. That could make him a contender to be 1st overall or he could slide down to the middle of the 1st round with a poor showing or even out of it like his LSU predecessor, Anthony Ranaudo, if an injury bites him.
Zunino was a good prospect in high school with raw power being his biggest asset. He wasn't a great prospect. He had raw power and a strong arm but the defense behind the dish was still progressing. He was drafted in the 20th round but chose to attend Florida. He did ok in his freshman year but broke out as a sophomore.
He is 6'2", 220 lbs and built like a solid backstop is expected to be. He has a strong, accurate arm and has a quick release. He isn't exceptional defensively but the arm will play and his work ethic will keep him behind the dish. He has added 25-30 LBS since high school and it was good weight. He is a more mature well rounded player now.
At the plate is where he wins you over. He can mash the ball. He has big raw power and it translates into game power. He knows how to work a count but has some swing and miss that will lead to a fair amount of strike outs like most players who hit for power. He should hit 20-25 homers and bat in the .270-.280 range. He is not fleet of foot. He's a below average runner but he is an intelligent player who should be able to maximize the speed he has.
Zunino has all the tools to be an above average starting catcher at the major league level. His swing is a little stiff but he has shown that will not detract from his production. In a draft where catching is heavy with talent he is the top talent. Without any injury or major setback, he should be in contention for the #1 overall pick and shouldn't make it out of the top 5.
Appel is considered by most to be the best pitcher in this year's class. He was a basketball player in high school so his baseball polish lagged behind. He threw 88-94 but had horrible mechanics. His time at Stanford has allowed him to gain consistency to his big 6'6" frame. He is currently 210 lbs+/- and could easily add 15-20 lbs more to add strength and durability. His command has come a long way, as has his consistency but he still needs work.
His fastball is a 93-96 mph pitch but can get up to 99. It didn't have much movement in the times I have watched him pitch. It looked rather hittable. His changeup is advanced. It can be a plus pitch and make hitters lunge at it but it didn't have a lot of movement in my viewings. It is a plus pitch that could get better with added movement. His slider is his best pitch. It has tight spin and looked very good in my viewings. His command of it wasn't advanced and he didn't locate it well. I think all 3 of his pitches could play up with more innings and confidence in locating them to all 4 quadrants. He
My concern with Appel is that he has the potential to be dominant but lacks...um..something. He tends to be around the plate. He leaves balls up in the zone and almost throws too many strikes. He suffers from "pitch to contact" syndrome; an affliction that many Minnesota Twins fans are aware of. If a team has a good defense behind him and he pitches with a little more killer instinct as well as develops more with instruction and better competition, he could be a frontline starter. If he doesn't gain those things and stays a similar pitcher, he may just be a #3 or 4 starter that you are always expecting more from. That being said, he should go in the top 5 without any complications and is likely to be the #1 or #2 pick overall.
Victor Roache, OF, Georgia Southern
Roache wasn't an elite follow out of high school. He came from Michigan and like many northern state players, has shown a lot of skill within a couple of years out of high school.
Defensively, Roache is an adequate corner outfielder. He doesn't have a rocket for an arm but it is strong enough to be useful and he is accurate. He covers enough ground and is a good enough athlete to be a solid outfielder. I don't see a positional change needed here although he is a big guy at 6'1", 225 lbs. I have heard he is a plus runner but I would rate him closer average.
At the plate is where the vast majority of his value is. He is a monster power hitter. He can crush the ball with wood or the weak BBCOR bats that were used last season in the NCAA. He hit 30 HR's in spring and 6 more in the Cape Cod league this summer. That is extremely impressive. The power will play. He uses his lower half well and has quick wrists and really gets good loft, but I'll get to that in a minute.
He has good plate discipline and doesn't swing at junk. The contact is where the concern lies. He has struck out a lot in his career, including 44 times this summer in about 180 plate appearances (not sure on the sacs, IBB..he had 136 AB). This is disconcerting to me. When I watch him hit, his hands are still moving downward when the ball is on its way causing him to uppercut at every pitch. This gives him good loft to his swing but makes him susceptible to good velocity, pitches up in the zone and makes him make less contact in general. That being said, players with power in college are scarce and he should be in the conversation for a top 10 pick this year. I don't see him at the same level of the top 4 due to the lack of contact ability and corner outfield status.

I have the same top five, different order
My top ten:
1 Mark Appel
2 Kevin Gausman
3 Deven Marrero
4 Mike Zunino
5 Victor Roache
6 Michael Wacha
7 Kenny Diekroeger
8 Marcus Stroman
9 Josh "Jake" Elander
10 Chris Beck
Similar question from last post, Matt. Who do you see as potential signability risks this year? Who do you think has a chance of dropping outside the first round, and who do you see jumping up in the rankings this spring and the draft this summer?
by cookiedabookie on Feb 9, 2026 9:09 AM EST reply actions
On your list
I think DIekroger could fall out of the 1st round pretty easily if he hits poorly and is a 2B instead of a SS and that’s what it’s looking like right now.
Risers could be any decent pitchers. Andrew Heaney out of Oklahoma State. Damien Magnifico for Oklahoma has hit triple digits this spring and could move up boards if the slider plays.
Signability shouldn’t be an issue for anyone drafted where they should be but Gausman is the best draft eligible sophomore and that could play into it.

i think for Diekroger
the key will be defensively if scouts think he can stick at SS
if scouts think that there’s a very high probability he can stick at SS, then some team late in the first round will draft him in the hopes that the bat develops. heck, i could see the Dbacks drafting him that late, if they are confident he will stick at SS.

+1 Diekroger
Not a first round guy at all for me.
Lost alot of his athleticism as he’s filled out, ave power at best, ave speed, no plate discipline and not a SS. No way he is even mentioned in the same breath as Marrero at this point and for me he’s more of a utility guy in the pros because he doesn’t hit enough to play a corner or field well enough to play up the middle
by ScottAZ on Feb 9, 2026 6:47 PM EST up reply actions
I'm rooting for him,
but he really needs to start delivering. It’s too bad. He looked decent as a freshman but really took a step back in 2011. I think the biggest thing is that he’s not a SS as you say. That really diminishes his value. I’m interested to see where the scouts have him this year. They held on pretty stubbornly to him and Jake Stewart as top guys despite lackluster performances from both; Stewart is even more frustrating at the plate, but at least he provides clear defensive value in the OF. It’s easy to get fooled when guys fill out the uniform at such a young age…
by charles wallace on Feb 9, 2026 6:57 PM EST up reply actions
the bbcor
the new bats killed guys with mirage power like Marrero and Diekroger. GMs must love it because it really does paint a more accurate picture of a kid’s power. With the old bats both these guys would be hitting 10-15 homers in college, with the -5 bats from the 90s both these guys would hit 15-20 homers in college. These new bats are “truth serum” as one of my scout buddies likes to say. I’ve even heard its easier to hit them out with wood than the bbcor.
Stewart has been a big dissapointment but, as you say, he has much more defensive value and fills in the uniform and is a physical speciman. His build is sort of like Trout’s and he can really play CF well for a big kid. Some team will draft him high in hopes he puts his tools to use in pro ball.
If college ball wasn’t such a showcase for the draft Stanford would be MUCH better off moving Ragira from 1b to Cf benching Stewart and opening up 1b for power bat Ringo, putting Kaupila at SS and moving Diekroger to 2B.
by ScottAZ on Feb 11, 2026 9:50 AM EST up reply actions
I've heard
that Kaupila will be at least splitting time at SS, and I’ve been waiting to see if they bite the bullet. I’m a big Ragira fan but I think he’s fringy in CF — could probably make it work at this level — but he’s definitely wasted at 1B, and would be on a corner if not for Gaffney. I think you probably keep enough runs off the board with Gaffney/Stewart/Wilson that it might be worth runnign Stew out there. Wilson is really fun to watch in the OF, that’s for sure. Beast.
The interesting thing about the bats is that I think Diekroger is strong enough to hit for moderate power with them, he just has a poor approach. Maybe he surprises this year.

how many Stanford games
do you catch a year? Sounds like you live in that area and are a fan.
Heres a question for you and one that is the most obvious comp: Austin Wilson or Michael taylor?
by ScottAZ on Feb 11, 2026 7:46 PM EST up reply actions
"Sounds like you live in that area"
I wish. While you’re spoiled by location, and I have friends in SoCal and FLA even more so, I’m trapped in the Midwest. Mostly catch games on-line and Stanford actually gets the occasional game on ESPNU. And of course I watch every post-season and CWS game I have time for. And re Wilson, you don’t need more than a couple games to marvel at the fielding. I was pleasantly surprised with his approach at the plate as well. Shorter swing than expected for a guy his size and he absolutely crushes when he makes contact, but he is raw like sushi in many regards. Easy to dream on that athleticism and you see why he was such a tremendous draft prospect.
I never saw Taylor when he played at Stanford. Do they comp well for you? If so, that might be alarming to AW fans!
by charles wallace on Feb 12, 2026 10:11 AM EST up reply actions
re:
at this point they comp to me. both very raw, not filled into their massive frames, but super athletic for their size, decent discipline, cannon arms, speed, monster raw power. taylor never really put it together while at stanford aside from his last month his junior year which really propelled him up in the draft. their numbers will probably be pretty comparable or wilson may actually fare worse due to bbcor.
I get to see Stanford 2-3 times in person a year, but I also get Fox Sports Bay Area that regularily broadcasts their games as well as ESPN U. I think all said and done I see them 10+ times a year. I usually just skip around unless a Ragira, Wilson, Diekroger is up to bat or Appel is pitching. I love college baseball and at this point probably watch more college than pro
by ScottAZ on Feb 12, 2026 10:57 AM EST up reply actions
of course
there is also always the question of the dreaded “stanford swing” in which they preach standing tall and stiff, passive contact based approach in which you let the ball travel deep and let the trampoline aluminum bats provide all the power on contact. maybe marques will change this a little do to the bbcor. probably not because he’s been doing the same thing for 25 years.
the stanford swing works for guys like sam fuld, but scouts hate to see it with the taylor, mayberry, wilson, garko, etc types because they don’t incorporate their lower halves, don’t look to open up and drive for power, and are generally too passive
by ScottAZ on Feb 12, 2026 11:09 AM EST up reply actions
"stanford swing"
I’ve been trying to see if that was the case with Wilson, but then, who wouldn’t teach him to stay fairly tall and let the ball travel? Considering his size and athleticism I might try having him emulate Mike Stanton’s stance.
I definitely think that approach is part of what dooms Diekroeger right now, and maybe a team with that in mind thinks they can get more out of him with an overhaul a la Brandon Belt. Mayberry finally started to put it together last year, but that was as much due to advances in pitch recognition as to the (considerable) work to shorten his swing. I’m with you on college ball. I still watch more pro ball by far, but college is no less compelling.

Thanks for these writeups
I’m trying to get more knowledgeable on the draft scene and it can be tough to find detailed info on these guys without subscriptions, which I can’t afford right now. Based on what I’ve read I agree that these 5 are the top 5, but I would probably rank them Zunino - Marrero - Gausman - Roache - Appel.

Nice write up
Twins picking #2 this year so paying more attention than normal. How long do you think Marrero would need to stay in the minors before coming up?
by Gunnarthor on Feb 9, 2026 10:38 AM EST reply actions
With the signing deadline
moved to mid-July, he should get some time in pro ball this year. If the Twins would draft him, I would bet he wouldn’t be up until late 2014 at the earliest. He could be up a little earlier if a team pushes him.
by Matt Garrioch on Feb 9, 2026 11:22 AM EST up reply actions
Your report from seeing Appel just makes me more nervous about him
I also don’t like Marrero as much as most. He doesn’t walk nearly enough. To actually be an above average offensive player he will need to reach the upper end of his hit tool projection. Because his patience projects so poorly, he’ll need to consistently be around .300 to have an above average on-base percentage, and his power projects to be average as well.
His 12% strikeout rate and .315 batting average last year don’t fill me with confidence he can be a plus-plus hitter.
He looks like a guy who has a very good chance to a MLB player but little to no chance to be an elite talent and not that great of a chance to be an above average regular.

Agree somewhat
I am a bit concerned that Marrero is sounding a bit like Christian Colon did before the 2010 draft. A safe pick who should stay at SS and could have above average offense for a SS. A high floor, low ceiling type that probably shouldn’t be taken as high as he will be.
by cookiedabookie on Feb 9, 2026 11:05 AM EST up reply actions
the thing is
if you have a high probability of batting 280/330/400 and can stick at SS
that seems insanely valuable to me. i feel like you can’t pass that up if you have a top five pick.

I'm skeptical he'll manage to walk enough for .330 OBP with a .280 BA
I think his most likely outcome is an average ML shortstop like Matt said. I’m just not sure how much upside he has beyond that. I think he tops out as above average but not a star player. That’s a quality prospect but more a top 10 prospect than a top 3 prospect in my opinion.

re Christian Colon,
Marrero is on another plane defensively, which is a good deal of his value, and I say that as a Colon fan. Whereas has a chance to stick at SS and be an Orlando Cabrera type, Marrero s/b an impact glove. I can see the concerns over patience, but college walk rates don’t have a clean linear correlation to pro projection, and guys like Gary Brown ( as one recent example) have shown that that can be overcome.
by charles wallace on Feb 9, 2026 12:21 PM EST up reply actions
he had
a slightly under 6% walk rate last year, and a higher walk rate the year before
even terrible hitters like Alcides can walk around 4% in the majors. to get a 330 OBP, Marrero needs to basically have a 5-6% walk rate (assuming 280 BA). from what it sounds like, he should be a better enough hitter than Alcides to get that type of walk rate. even if he doesn’t, and only gets a 4% walk rate, that’s not a killer i guess.
mostly, i think whether he will be able to make it to the majors, is going to depend on how the hit tool translates to pro ball. if he can really put up 280ish BA, which is what it sounds like right now given his contact abilities, i think he can be pretty valuable as a SS.
by blue bulldog on Feb 9, 2026 3:22 PM EST up reply actions
Colon
looked like a future 2B to me. That made him less valuable in my eyes.
Even if he hits .260, 10HR’s with plus defense(60), he’s still an average MLB SS. I think he can exceed that and that is a very valuable commodity. I wouldn’t take him #1 but I’d think hard any pick after that.
by Matt Garrioch on Feb 9, 2026 11:30 AM EST up reply actions
Is it wrong
For me to liken his value profile to a shortstop version of what Jason Castro was when he was drafted a few years ago? Being a shortstop, that gives Marrero more plate appearances and less likelihood of injury, so a bit more value. But in all other ways he reminds me of Castro’s profile… above average defender up the middle, average offensive player.

I'm not a good one to ask about
Castro because I have never liked him as a prospect. I agree with “above average defender up the middle, average offensive player.”

BBCOR bats
Marrero is better all around. better athlete, more range, better arm, more offensive upside. Marrero in 2010 as a freshman put up better offensive numbers than Colon did as a jr.
With the previous bats Marrero would be showing much more power.
If anything, these new bats show a clearer picture of what the player will relaly do, although the numbers look alot less glamorous to the naked eye
by ScottAZ on Feb 9, 2026 12:55 PM EST up reply actions
Fair enough
I have him ranked 3rd for college draftees, so I am not too concerned about it. But whenever people question his bat, it makes me think of Colon.
by cookiedabookie on Feb 9, 2026 4:33 PM EST up reply actions
Marrero
As someone who catches 15-20 ASU home games at Packard every year I feel qualified enough to add my 2 cents on Marrero.
He is a very good player to be sure, but I was shocked when I started to hear talk of him going 1-1. I just don’t see him being that type of impact player. Here’s how I’d rate his tools:
Hitting: I see him a future 60 or 65 here. He can put a sting into the ball even though he doesn’t have big homerun power and he can use the entire field. In college I’ve seen him drop his hands and turn on and crush inside pitches and also hit one hoppers oppo that shorthop the wall. He will have to focus on plate discipline. Breaking balls in the dirt have especially been his nemesis.
Power: As mentioned above, he has some power but dont expect too much. 10-15 bombs seems about right. An issue he has is he swings for the fences a lot, which doesn’t play into his size or skill set. As mentioned above, I’ve seen him drop his hands, open his hips, and pull some monster bombs, but he takes this approach too often and need to focus more on peppering the gaps with liners and hitting the occasional bomb. Overall I see about 50 power here.
Speed: As others have said, very athletic and quick but not a burner. He’s pretty aggressive and savvy on the base baths and I could see him stealing 20 bases a year despite speed at about 60.
Defense: Plus range, goes to the hole well. Makes plays no other college SS’s can. His error totals have been high in college, mostly on throws. He occasionally doesn’t set his feet and will pull a 1B off the bag. His other errors are on forced throws after making diving plays or plays deep in the hole or up the middle. Once he learns to eat those plays he’ll be fine. I can seem him being a 65 defender. Not necessarily a Gold Glover, but an above ave defender.
Arm: Again, maybe the best SS arm in college ball. I went to the CWS in 2010 and watched the ASU/Clemson pre-game to comp marrero to Clemson’s Brad Miller who was getting considerable hype as a pro quality defender. It wasn’t even close. marrero’s arm was a full grade higher than Millers and at that point I realized how strong Marrero can bring it. I’d give his arm a 70
Overall, I see marrero being a quality MLB SS, but not a difference maker. More of a guy that plays good defense and bats in the lower third of the order providing something like a 280/320/420 type slash with 12 HR, 20 steals, and his share of doubles and triples.
lastly, although he’s listed at 6’1", 175 he is more realisically around 5’11" or 6’0" and weighs closer to 150-160
by ScottAZ on Feb 9, 2026 12:52 PM EST reply actions 1 recs
Well said Scott
My only response there is that a .280 hitter (60), 12 HR’s (45 power), 20 steals (65 speed, as you said it plays up), 65 D and 70 arm is a 61 OFP player. Knock his speed to a 60, he’s still a 60 OFP player and that is a well above average SS and an occasional All-star.
He isn’t a 1-1 talent in most drafts. That is true, but he is a sure fire MLB player and a top 10 talent in most drafts. The college pool this year just isn’t that great and that’s the only reason he is getting 1-1 talk, IMO.
by Matt Garrioch on Feb 9, 2026 1:00 PM EST up reply actions
Agree
He’ll be a high level SS in the Bigs. I think he’s a 1st round talent, but I wouldn’t go 1-1 for him.
IMO, he’s better in EVERY catagory than Christian Colon. Better athlete, more range, better arm, more power. Only thing Colon has on him is plate discipline.
Marrero’s lack of discipline will keep him from being an elite pedroia type of offensive performer and will probably restrict him to the bottom third of the order

that's the thing
if he has a high probability of 280/320/420 (which is basically what i think, though i actually have his power a little bit lower than that)
then that’s amazing. that’s 2011 Erick Aybar as a SS. good SS are so rare, that i think you can’t pass on that if you’re picking so high in the draft. maybe not 1-1 (if guys like Giolito are showing tremendous upside), though you could certainly make the argument for 1-1. but if I’m drafting in the top 5, and I ended up with a guy who’s putting up 4+ WAR at SS consistently, I’d be extremely pleased.

Appel writeup
I’ve also had the luxury of watching Appel pitch 3 times in person. I will do a writeup on him when I get a little more time.
He’s worthy of a 1st round pick, but he has underachieved given his size and stuff.
I wouldn’t be the least bit surprised if pac10 pitchers like UofA’s Heyer and our (ASU) Brady Rogers have longer and more successful careers
