40 Jose Tabata NYY OF B Finally hit first HR on May 21. .275 AVG in May is much better than .200 April mark.

41 Beau Mills CLE 1B B 15 doubles hints at his power potential and .257 AVG is the result of some bad luck.

42 Elvis Andrus TEX SS B Scouts say the power will come (0 HR) and the defense and speed (19 SB) are already there.

43 Chris Davis TEX 1B B .995 OPS got him the AAA promotion. Not too far from the Rangers. 13 BB the only concern.

45 Max Ramirez TEX C B Nice job by TEX getting him for Bob Wickman. Just killing the ball - 1.167 OPS.

22 Jordan Walden LAA SP B+ 2.25 ERA in four May starts. I'd like to see him get that 7.0 K/9 up a bit before bumping him up.

23 Neftali Feliz TEX SP B Time for a promotion - last 6 GS - 33.1 IP, 1 ER, 32:7 K:BB. Fast riser.

24 Deolis Guerra MIN SP B+ 7 BB in last start contributes to ugly 29:21 K:BB. Just a 5.33 ERA and 3.6 K/9 in May.

25 Ian Kennedy NYY SP B+ Strained lat lands him on DL and it might be awhile after his return that he makes rotation.

31 Jeremy Hellickson TAM SP B 7 ER and 16 H over 10 IP last 2 GS but he's been incredible overall - 64:4 K:BB is just sick.

36 Michael Burgess WAS OF B 11 HR in 48 G leaves little doubt about power potential, but 64 K is the big concern.

38 Chin-Lung Hu LAD SS B Bat has been a disappointment. Big question: contract extension for Rafael Furcal?

39 Josh Vitters CHC 3B B Still out with a hand injury in what is looking like a lost year.

47 Todd Frazier CIN SS B 1,000 OPS got him early promotion to High-A. Reds need long-term SS, but it probably won't be him.

49 Chris Coghlan FLA 2B B Lots to like here: .372 OBP, 15 SB, 0.85 EYE and 15 HR potential.

40 Colin Balester WAS SP B Better than 4.65 ERA indicates, but HRs have been a huge issue - 11 in 50 1/3 innings.

42 Jordan Zimmerman WAS SP B For the year - 2.06 ERA, 9.7 K/9, 2.9 BB/9. He's rising fast.

45 Madison Bumgarner SF SP B 19 in AUG. Last 6 GS: 27.1 IP, 23 H, 1 ER, 6 BB, 38 K. Wow.

48 Jeremy Jeffress MIL SP B Came back from suspension with 10 K in 5 IP in 2nd start. Could rocket up this list if he stays clean.

50 Tim Alderson SF SP B 6-2, 3.68 for 19 year-old in High-A is impressive. K/9: May - 8.1, April - 5.7.
