Oakland Athletics Top 20 Prospects for 2012
Oakland Athletics Top 20 Prospects for 2012
The list and grades are a blending of present performance and long-term potential. Comments are welcome, but in the end all analysis and responsibility is mine of course. Full reports on all of players can be found in the 2012 Baseball Prospect Book. We are now taking pre-orders. Order early and order often!
QUICK PRIMER ON GRADE MEANINGS:
Grade A prospects are the elite. They have a good chance of becoming stars or superstars. Almost all Grade A prospects develop into major league regulars, if injuries or other problems don't intervene. Note that is a major "if" in some cases.
Grade B prospects have a good chance to enjoy successful careers. Some will develop into stars, some will not. Most end up spending several years in the majors, at the very least in a marginal role.
Grade C prospects are the most common type. These are guys who have something positive going for them, but who may have a question mark or three, or who are just too far away from the majors to get an accurate feel for. A few Grade C guys, especially at the lower levels, do develop into stars. Many end up as role players or bench guys. Some don't make it at all.
A major point to remember is that grades for pitchers do NOT correspond directly to grades for hitters. Many Grade A pitching prospects fail to develop, often due to injuries. Some Grade C pitching prospects turn out much better than expected.
Also note that there is diversity within each category. I'm a tough grader; Grade C+ is actually good praise coming from me, and some C+ prospects turn out very well indeed.
Finally, keep in mind that all grades are shorthand. You have to read the full comment in the book for my full opinion about a player, the letter grade only tells you so much. A Grade C prospect in rookie ball could end up being very impressive, while a Grade C prospect in Triple-A is likely just a future role player.
1) Jarrod Parker, RHP, Grade A-: Borderline B+: Acquired in Trevor Cahill trade. I wish his strikeout rate was higher and I think he needs some Triple-A time. I don't think he uses his breaking stuff as much as he did pre-injury, but overall he still looks like a future rotation anchor to me. The risk may be higher than some anticipate, but the ceiling is quite high.
2) Michael Choice, OF, Grade B+: Don't expect great batting averages, but should produce plenty of power and walks. Expect a very productive career as a slugger.
3) A.J. Cole, RHP, Grade B+: Acquired from Nationals in Gio Gonzalez trade. I really believe in his upside. Needs to build stamina and refine his changeup, but if it comes together he could be a Top 20 pitching prospect next year, perhaps more.
4) Brad Peacock, RHP, Grade B: Borderline B+. Acquired in Gonzalez trade. Still has some command issues, but his ERAs finally caught up with his components and his overall potential in 2011. Will be ready before Cole but his upside is not quite as high. Future 2/3 starter if all works out.
5) Sonny Gray, RHP, Grade B: Borderline B+: 2011 first-round pick, impressive fastball/curveball combination. Assuming proper development of changeup, should be a number 2/3 starter.
6) Derek Norris, C, Grade B: Acquired in Gonzalez trade. Loads of power, walks, and scouting reports on his defense are getting more positive each year. Ranking may seem high for such a low batting average, but I see him as a Mike Napoli (pre-2011)/Mickey Tettleton type who can be productive even with a low average.
7) Grant Green, OF, Grade B-: Less impressive as an outfield prospect. I think he will be stretched to play center and will need to show more power and/or plate discipline to be a classic corner outfielder. Still has a chance to blossom.
8) Tom Milone, LHP, Grade B-: Acquired in Gonzalez trade. At some point, the radar guns stop mattering. The guy can simply pitch. He has little margin for error, but he will probably have a better career than hundreds of guys who throw 10 MPH harder.
9) Chris Carter, 1B-DH, Grade C+: No, I haven't given up yet. Still has a shot at being a 25-30 homer guy with a good OBP.
10) Collin Cowgill, OF, Grade C+: Acquired in Cahill deal with Arizona. Good balance of skills, should be a fine fourth outfielder.
11) Raul Alcantara, RHP, Grade C+: Acquired in Andrew Bailey deal with Red Sox. Live arm with good results in rookie ball, still refining his secondary pitches. High ceiling.
12) Michael Taylor, OF, Grade C+: Rebounded some, still has good tools, but his window of opportunity will close soon as Choice and Green catch up with him.
13) Josh Donaldson, C, Grade C+: He looks like a solid role player to me, has some pop, improved defense.
14) Aaron Shipman, OF, Grade C+: Draws walks, has blazing speed, no power yet but still young enough to develop it. Transition from New York-Penn League to Midwest League in 2012 will be illuminating.
15) B.A. Vollmuth, 3B, Grade C+: Power hitter out of Southern Mississippi, former shortstop needs to adapt to third base. Will probably strike out a lot but provide plenty of pop.
16) Vicmal De La Cruz, OF, Grade C+: Good tools, performed well in Dominican Summer League, could rank much higher once we see him in North America.
17) Steve Parker, 3B, Grade C+: Power production dropped in Double-A but still controls strike zone well. Nothing special with the glove, but could be useful role player.
18) Daniel Straily, RHP, Grade C+: Strong performance in California League, reports on stuff are promising. Under-the-radar prospect will need to prove that he can duplicate this at higher levels, but a sleeper.
19) A.J. Griffin, RHP, Grade C+: Pitched at four levels last year, showed superior command of average fastball but solid breaking stuff and strong changeup. Sleeper.
20) Miles Head, 1B, Grade C+: Acquired from Red Sox. Ineffective in the New York-Penn League in '10, but something clicked last year, hit for power and average in Low-A. Power carried forward to High-A but he's got contact issues to work out, and right-handed hitting first baseman have an uphill battle. Could rank much higher next year.
21) Ian Krol, LHP, Grade C+: Missed almost entire season with elbow problems and suspension over offensive anti-gay tweet. Looked good in instructional league. When healthy and not acting like a douche, he has a chance to be a mid-rotation starter.
22) Ryan Cook, RHP, Grade C+: Acquired in Cahill deal. Throws hard, would fit nicely as a middle reliever if his command is strong enough. Should contribute in 2012.
OTHERS: Yordy Cabrera, SS; Adrian Cardenas, 2B; Andrew Carignan, RHP; Bobby Crocker, OF; Rashun Dixon, OF; Blake Hassebrock, RHP; Chad Lewis, 3B; Jermaine Mitchell, OF (good tools, great numbers, but old at age 27); Renato Nunez, 3B; Chih Fang Pan, 2B; Gregory Paulino, RHP; Nick Rickles, C; Max Stassi, C; Beau Taylor, C; Blake Treinen, RHP; T.J. Walz, RHP.
This system was looking pretty thin until the flurry of trade activity this off-season. You now have the nucleus of a future starting rotation with Parker, Cole, Peacock, Gray, and possibly Milone, plus some staff-filling arms backing them up.
Hitting-wise even the best prospects (Choice, Norris, Green, Carter) have a concern of some kind, although if things pan out the Athletics will have an impressive group of power hitters who also draw walks. There are several who should be fine role-players. There are some guys with intriguing tools who need to develop some skills but have at least some chance to make an impact, particularly Shipman, Volmuth, and De La Cruz. Investments in raw tools players like Yordy Cabrera, Rashun Dixon, Renato Nunez, and Chad Lewis haven't paid dividends yet but they are all still quite young. Max Stassi still has a chance if his shoulder comes around. A pair of college catchers drafted in 2011, Nick Rickles and Beau Taylor, are promising.
Overall, I think they did a good job restocking their farm system.

Not surprising. He was 19 years old playing against high school kids the year he got drafted. Recall the great bit of research that was posted about 6 months ago showing that HS draftees in his age group have a very bad success rate in pro ball.

I think all of the pre-draft concerns came to a head because of last year's performance
That he was a year older than his HS competition, that his power would evaporate, and that there’s not a chance he’ll stick at SS. While he obviously has time to turn things around, all in all his performance was probably the most disappointing out of recent A’s draftees.

Krol
Wow. Didn’t know about the tweet/suspension.
Unfortunately, this (team suspension) is nothing new for Krol. He got suspended for the entire season (read: kicked off the team) for an alcohol infraction in high school. And the reason it was for the season was because it wasn’t his first infraction. He had multiple chances to stay on the team, but chose to make poor decisions and it seems like he’s yet to grow up.

Absolutely
And as an A’s fan, I’m proud of the way the organization handled it. Doesn’t matter what kind of talent you have, they will not put up with that behavior, and if you do engage in it, then there goes your season.
I hope this is a precedent teams will follow in the future.

Krol
I actually went to High School with him. He was a class above me, due to birth date. He’s not the brightest kid, but is very talented when it comes to baseball. I remember when he got his dui, which effected where he played baseball his senior season and if he was going to college at Arizona. I hope he proves me wrong and does mature, but he’s one of those guys that it’s hard seeing it happen.

You have Vollmuth listed as a 3B but say he
needs to adapt to first base.

Like the list
hopeful that AJ Griffin and Dan Straily can repeat next year at AA, maybe even jump to AAA at some point, if parker, gray, peacock, or milone are brought up are called to the show

I'd be ok with Gray getting a full season in Sacto
the more he’s rushed, I think the more he’s likely to end up in the pen. If he gets a full year to really work his changeup into an above average pitch, it’ll serve him best. Milone is the only guy who should make the rotation out of ST, Parker and Peacock could use a couple months in AAA, both for development and to delay service time.

I would think only if he changes their grades later
In the introduction of every top20 list he states that there is clear diference between C and C+. Then he should clearly show which of the others section are C+. Since I haven’t seen that, I will read the others section as straight Cs.

I think auclairkeithbc is right.
There are sometimes C+’s in the “Others” section. Here’s a comment from John in the Cubs Top 20 discussion.

by stranahanahan on Jan 9, 2026 2:41 PM EST up reply actions
I see why he might not wanted to have repeated that in the book, but I have to think he'd
rank somewhere in the Top 40. Would John really trade him for Ryan Cook? If anyone would, they’d have to be really sure that he’ll never amount to anything. I understand Cook has a much better chance of pitching in the majors, but he also has basically no chance of ever being anything other than a middle reliever for a couple of years, no? Guys like that grow on trees.

by WaddellCanseco on Jan 9, 2026 5:22 PM EST up reply actions
why?
Ryan Cook sits mid-90’s with his fastball as a reliever
that alone should make him valuable as a reliever. if the command improves, or one of his secondaries improves a little more, he’d be a back-end guy.

how do you feal about adrian cardenas?
his minor league numbers look pretty good, he doesn’t strike out too much, he can take a walk, he just can’t hit for power
what do you see his role as on the team?

He wasn't that good in AAA this year, and it was his third time there.
I guess there’s an outside chance he finds some power and turns into Chase Utley-lite. But as of now, he looks like a career backup INF.

A sub-.800 OPS in the Pacific Coast League isn't really that great.
by NateHST on Jan 9, 2026 5:17 PM EST up reply actions
Yeah
No power, little speed, and a decent AAA walk rate that is likely to dip in the majors due to the lack of power. He’s put up fairly weak AAA numbers in a very offense-heavy league thus far. And the organization doesn’t think highly enough of his defense to give him even one full season - in the minors - at any position.
His value is almost entirely tied to making contact and having experience (though probably not great skill) at multiple positions. I’d say solid utility man is the absolute best case scenario.

Now that the lists have been posted for all teams, I dont think we ever saw grades for Grandal or Alonso, because they got traded before the Reds list posting but after the Padres list posting.

Major health and contact problems
He reportedly has great defense, but his bat has been terrible so far and he’s looking like a long shot. I’m still optimistic because he’s young and he posted that 30% K rate as a 19 year old. He’ll be 21 at high-A and really has to take a step forward this year.

Carter get his chance in 2012???
Carter is at the point where you give him the full time DH job to see what you’ve got. He has nothing to prove in AAA and he is always a slow starter. At 25+ yrs old and with a rebuilding team…. let it ride.
by zeuspower on Jan 9, 2026 5:29 PM EST reply actions
I agree but it's easy for us to say since we don't have to play alongside him, be benched
in favor of him, or manage players who do. Also I’m not sure he really has nothing to prove at AAA.

He just needs consistent at bats that the A’s, for whatever reason, refuse to give him.

Sonny Gray
I am a little surprised to see Gray at no. 5. I know it’s preliminary but Gray in a small sample has been impressive.
Parker, Gray and Cole all have very good upside, IMO, their ranking are interchangeable. But there is a talent drop-off from them to Peacock.
Overall, I have him as a solid B+, 1/2 starter. Below is the top ranking as I see it:
1. Parker, 2. Gray, 3. Choice, 4. Cole, 5. Peacock

Graduating to the majors: Taylor, Cook, (probably) milone, cowgill, (possibly) mitchell, and maybe parker or peacock, i see at least one of them being called up by july
going to be added to the prospect list: 5 picks from this year’s draft, possibly shawn duinkerk, possibly seong-min kim, and chris bostick if he can keep up production and doesn’t regress TOO much from last year

I’ll be excited to see what happens with the low level young guys: Cole, Nunez, Dixon, Stassi, Vollmuth, Shipman, Alcantara, Straily, Ynoa, and Head.

Hopefully the A's system behaves like a normal farm system in 2012

Maybe they also change things up from last year
by actually promoting true prospects (not guys like mitchell, timmons, mye, etc) mid year if they’re dominating (like they probably should have with straily or whitaker or andres avila), the only true prospect they promoted mid year was aj griffin

Would this have been the worst system in the majors without the trades?
Only one B+, 3 guys in the B range, 10 C+ and the #14 guy is a straight C. (And I actually think those grades are optimistic— I’d put Choice at a B and Green at a C+, and Shipman’s literally not even on my radar screen at this point. I might still put Carter at B- and could bump Straily there with some more detailed scouting reports.)
Seconding whoever said that the past few years have been brutal. Ridiculous, really. Two entire draft classes look like they might be washouts (2007 and 2009), and 2010 looks dismal too, if only by comparison to the unwarranted hype that guys like Cabrera and Shipman got.
