1) Jonathan Singleton, 1B, Grade B+: Acquired in the Hunter Pence deal with the Phillies. You can make a case for an A-, although he hasn't yet fully tapped into his natural power. I think he might need a bit more time than people think, but still an elite prospect.
2) George Springer, OF, Grade B+: Much broader tool base than Singleton, but exactly two years and one day older, which makes a difference. I think he made real progress with his swing and contact ability this year. Impressive power/speed/walks package even if he doesn't hit for a high average.
3) Jarred Cosart, RHP, Grade B: Excellent arm strength, but pitchability seemed to take a small step backwards last year. Strikeout rate is low for a guy who throws as hard as he does and he needs command refinements. Another part of the Pence trade.
4) Jonathan Villar, SS, Grade B-: He's very young, has been pushed too quickly in my view, and has some serious contact problems to resolve. He also has double-digit homer and steal potential and great defensive tools. High risk, high-reward player. Grade A tools, grade C skills.
5) Paul Clemens, RHP, Grade B-: Part of the Michael Bourn deal with the Braves. Solid stuff, has made progress with command, projects as a number three or four starter for me.
6) Mike Foltynewicz, RHP, Grade C+: I probably like him more than I should. Strong fastball, secondary pitches still works-in-progress but I think he can be a mid-rotation guy if everything works out.
7) Domingo Santana, OF, Grade C+: Exceptional power potential and was just 18 years old in the Sally League. He's also got serious issues with strikeouts/contact and plate discipline. Similar problems have killed many careers. Like Villar, Santana has a very high ceiling but a very low floor.
8) Brett Oberholtzer, LHP, Grade C+: Part of the Bourn deal with Atlanta, average velocity but mixes his pitches well. Could be a nice number four starter but not a huge upside.
9) Delino DeShields, 2B, Grade C+: Another high-ceiling low-floor high-risk guy with tools who lacks refinement. Hit just .220 in the Sally League but swiped 30 bases.
10) Adrian Houser, RHP, Grade C+: Second round pick from an Oklahoma high school, performance in rookie ball was spotty but could develop into a number three starter.
11) Telvin Nash, 1B-OF, Grade C+: Enormous raw power, but fanned 105 times in 281 at-bat in Low-A and GCL rehab assignment. Little defensive value. Cecil Fielder-like upside if he can make enough contact but that is a big IF.
12) Nick Tropeano, RHP, Grade C+: Stony Brook product lacks plus velocity but changes speeds extremely well, could develop into a solid inning-eater type.
13) Austin Wates, OF, Grade C+: Hits for average, swiped 26 bases in High-A, good athlete, but lack of distance power could be a hindrance.
14) Jiovanni Mier, SS, Grade C: The Astros have not given up on him, still young, athletic, respected defense, but hitting is very questionable.
15) Tanner Bushue, RHP, Grade C: Still projectable and young, but progress has stalled and he's had problems staying healthy. Too young to give up on of course at age 20.
16) Juan Abreu, RHP, Grade C: Older prospect acquired from the Braves, but has a lively arm and can be very effective middle man if he maintains his command. If you want immediate impact rank him higher than this.
17) Ariel Ovando, OF, Grade C: Impressive power potential but did not hit well in the Appalachian League. Given the $2,600,000 invested in him, they will be as patient as possible and he's just 18.
18) Ross Seaton, RHP, Grade C: Still has the raw material to be a good pitcher, and he's been badly rushed. It would not surprise me to see him perform much better in his second attempt at Corpus Christi.
19) Jake Buchanan, RHP, Grade C: Doesn't have a high upside, but keeps the ball down, throws strikes, and was one of the few pitchers able to survive and prosper at High-A Lancaster. Sleeper guy to watch for 2012.
20) Chris Wallace, C, Grade C: Like Buchanan, Wallace is a college product (University of Houston in his case) who doesn't have a high upside but could be a useful role player, in this case as a power-hitting catcher with fair defense. Power-hitting first base prospect Kody Hinze would also fit in that category although he'll have less glove value.
