30 Austin Jackson NYY OF B+ 23:17 K:BB and 82% CT% are fine, but where's the pop? 0 HR in 125 at-bats.
43 Jose Tabata NYY OF B Discipline issues and batting just .232. Is 8-for-15 in last 4 games however.
44 Beau Mills CLE 1B B The bad: .233 AVG. The good: 20:24 K:BB. .290 AVG though in last 9 games.
46 Ben Revere MIN OF B Nice debut: .432 with 3:3 K:BB in 37 at-bats. .236 ISO isn't sustainable, but it's good to see.
49 John Shelby CHW OF B College guy with intriguing tools and savvy. Son of the ex-big leaguer with the same name.
15 Fautino de los Santos OAK SP A- Shut down with a sore elbow. Hopefully nothing serious, but maybe it explains his 5.87 ERA.
19 Jordan Walden LAA SP B+ Has been so-so in last three starts, but he's generating a lot of GBs and has great stuff.
20 Adam Miller CLE SP B+ 11 hits in 3.2 innings last time out is a huge concern. Hope the elbow is okay.
25 Ian Kennedy NYY SP B+ Awful for the Yankees as he wasn't commanding his fringy stuff. 7.1 S.O. innings in 1st AAA start.
27 Luke Hochevar KC SP B+ 4.86 ERA in three starts. Not sure if he's going to stick, but he'll make 20 big league starts this year.

14 Andrew McCutcheon PIT OF A- .360 in last 6 games and .290/.389/.508 overall with 6 HR and 9 SB. Time to trade Bay or Nady.
15 Geovany Soto CHC C A- No longer a true "prospect" like others on this list. Will drop off list later this month.
17 Chase Headley SD OF A- Hit just .242 in April, but now .412 in last eight games. Should be SD LF by midseason at worst.
22 Matt Antonelli SD 2B B+ 4-for-12 with HR in last 3 but still just .196 on the year. 20:19 K:BB does give us some hope.
23 Jason Heyward ATL OF B+ Doesn't turn 19 until Aug. .307/.345/.433 with 8 SB. Power will come.
7 Homer Bailey CIN SP A 23 K in last 20 IP. 2.72 ERA in 7 GS and shouldn't be too far from replacing Matt Belisle.
10 Jarrod Parker ARI SP A- It's not fair how much great pitching the Dbacks have. One run or less in all five starts for Parker.
21 Carlos Carrasco PHI SP B+ Got beat up on 4/23 but rebounded to win last two starts. Overall - 39:14 K:BB in 36 IP.
24 Tommy Hanson ATL SP B+ May be a late-season call-up at this rate - 0.90 ERA, 49:11 K:BB in 40 IP.
36 Jair Jurrjens ATL SP B 2.08 ERA in his last four starts. Seems he's up to stay.
