On March 1st, Bullpen Banter released its top 25 prospects and since then, each of our top 25 prospects write ups have been viewed, and readers have left some fantastic comments. Today, we are releasing our next 25 prospects, numbers 26-50.

Like our top 25, each prospect has an introductions, like this one of Starlin Castro,

SS Starlin Castro was signed out of the Dominican Republic by the Chicago Cubs in 2006 for $50,000. He made his North American professional debut in 2008 at age 18, showing a surprisingly refined bat for his age and splitting time between 2B and SS with fellow touted international signee Junior Lake. After impressing Cubs officials during 2009 spring training, the team decided to challenge Castro by pushing him to the Florida State League, a difficult assignment for any teenager. Castro rose to the challenge, batting .302 and earning a promotion to Double A Tennessee, where he held his own. Castro gets a lot of praise for his mature hitting technique and deceptively strong strike zone judgment, although his slight build suggests his power ceiling is around 15 HR/season. While scouts are concerned that he may have to move off of shortstop in time, Castro's offensive potential and solid across-the-board tools give him a good chance to be an impact player at any number of positions. The Cubs certainly feel so, as Castro is reportedly on the fast track to the major leagues and could see major league time before the 2010 season is out.

Additionally, we've added our own our own two cents on each prospect. Here are a few samples after the jump...

Both positive:

Brett Lawrie (34)

Stephen Kuperman: I LOVE Brett Lawrie, as you can tell from my aggressive placement of him on my top prospects list (#18). His bat has franchise player-type potential; he makes good contact and has terrific bat speed that contributes to his tremendous raw power. His strike zone judgment is pretty good already and stands to get only better. It's hard to remember that Lawrie is only a year removed from playing against Canadian prep competition, so the gap between what he is and what he could be is much more pronounced than a lot of other players. Even still, his 2009 production in the Midwest League was quite good.

The other thing to remember with Lawrie: in 2008, this guy was busting up advanced minor leaguers pretty well as an 18 year old in Olympic competition. I'm not sure where he ends up defensively, but I'm not sure it really matters all that much. He's a future middle of the order presence in any case and one of my favorite prospects.

and negative:

Brett Wallace (38)

JD Sussman: I've got to say, I'm not a fan of Brett Wallace (can I move him down on my list?). Wallace is a first baseman who doesn't have stand out power. I can't see him putting up an ISO above 200 at the major league level. Additionally, he doesn't make up for it with outstanding plate discipline like Logan Morrison does (he projects to walk around 6-7% of the time). To me, Wallace is simply a below average starter at 1B.  He does have soft hands, but he doesn't project as defensive wizard, even at first. Looking at WAR, he is a +7.5 runs with bat, a -2.5 defender, and he'll get 8 runs if he starts everyday at first (-12 for 1B, +20 for playing). But to me, he isn't a first division starter (but then again, the Jays aren't a first division team).

Also, here is a taste of some strong arguments from Al and Michael:

Matt Dominguez(49)

Matt Dominguez, 20, was the Marlins' first round 2007 draft choice out of Chatsworth, CA. Known for his superb defensive ability, the Marlins' third baseman started the year playing for High-A Jupiter in the extremely pitcher friendly Eastern League. He still managed to put up a respectable line of .262/.333/.420. He finished the season at AA Jacksonville in the Southern League, batting .186/.292/.320 in 31 games. Dominguez has above average power, and we predict he'll have a breakout year at AA Jacksonville in 2010.

Michael Herrick: Matt Dominguez spent the majority of his age 19 season in the pitcher friendly FSL, playing his home games in the notorious hitting hell hole of Jupiter. All Marlins hitters that play in Jupiter see a drop in their power numbers as the park is just a very difficult hitting environment. Even Mike Stanton suffered a 35 point drop in his ISO when he moved from the Sally League to the Florida State League. With that in mind, the surface stats for Dominguez appear to show a down year but there is quite a bit to be pleased with honestly. Dominguez dropped from a .296 batting average to a .262 average, I don’t think either is a true representation of what he’s going to do in the future-he’s probably somewhere in the middle as his BABIP was a bit above average in 2008 and a bit below average in 2009. Even with that 34 point drop in average, he only suffered a 21 point drop in OBP as he raised his walk rate from 7.3% to 8.9%. His ISO dropped 46 points but he did raise his XBH% from 33% to 37%. I’m not worried about his power as he possesses 20-25 HR pop in his bat and will show that as he moves up and fills out his frame a bit more as he matures physically. Matt also cut his K rate from 19.7% to 17.8%, which is impressive when you consider his ARL and the league he played in. Dominguez projects as a plus defender at 3B as well, TotalZone rates him as +18runs/150 in 2009. Dominguez is far from a finished product as his short stint in AA at the end of 2009 showed, he needs more time to refine his tools into skills and to make adjustments against more advanced pitching. This is a major reason why in our Florida Marlins preview I thought they should have been aggressive in the free agent market and pursued Adrian Beltre. Dominguez likely needs a full year in AA and a full year in AAA to put the finishing touches on his game, and Beltre would have bought them that time without the temptation to rush him along. Now the Marlins must remain patient and not push him too far, too fast or they risk wasting a year or two of service time while he figures things out. Matt ranks #43 on my list and could move into the top 25 next year with a strong 2010 campaign in AA.

Al Skorupa: Yup. The park and league effects and luck are hiding actual progress here. He's such a superb defender that even if his bat isn't what I think it is he should be a pretty valuable major leaguer.

The one issue that concerns me is his ability to handle breaking balls and offspeed stuff. The reviews haven't been all that positive. I still like his feel for hitting and think he's a guy who could shoot back up the prospect lists next season.
