National League

1 Bryce Harper WAS OF A+ The Nats made it official in the past week, saying no 2011 MLB debut for Harper.

7 Domonic Brown PHI OF A .341 in AAA and now will play regularly in Phil with Victorino on DL.

21 Billy Hamilton CIN SS B+ 31 hits, 37 SB. Incredible. 13 SB in last 8 games. Just imagine if he could actually hit.

24 Jerry Sands LAD 1B B+ Gained 70 points of OPS with a four-hit game over the past weekend.

42 Paul Goldschmidt ARI 1B B .333/.469/.693 with 15 HR and 1.4 EYE. Team has 1B logjam at both AAA and MLB.

1 Julio Teheran ATL SP A Back down again after unimpressive spot start #2. Only really interesting in keeper leagues.

2 Shelby Miller STL SP A Ridiculous numbers - 13.5 K/9 and .169 avg vs RH hitters. Time for AA.

17 Casey Kelly SD SP B+ 4.29 ERA through 9 GS, but given age, upside, and Petco, has very good fantasy upside.

19 Randall Delgado ATL SP B+ 2.37 ERA and 48:20 K:BB in 49.2 innings. Status is rising.

21 Rubby De La Rosa LAD SP B+ Gets the call to help out beleaguered Dodger bullpen. Long term hopefully a starter.

American League

2 Mike Trout LAA OF A+ .308/.415/.538 with 9 SB. No indicaton he'll be more than a Sept. callup.

3 Jesus Montero NYY C A 11-for-26 vs LHP, but hey, when you have the great Jorge, who needs Montero?

4 Mike Moustakas KC 3B A Just .264, but no one is worried about his bat and the power is obviously there.

13 J.P. Arencibia TOR C B+ Will lose eligibility for this list next week. Power certainly there so far with 8 HR.

14 Jason Kipnis CLE 2B B+ .326 in May and overall an .864 OPS and 8 SB. Excellent fantasy prospect.

5 Jacob Turner DET SP A- 8-5-2-2-1-8 last time out and seems like a lock for the 2012 rotaiton.

6 Martin Perez TEX SP A- 4.5 BB/9 but appears to be getting better there lately.

11 Drew Pomeranz CLE SP A- 2.09 ERA and 12.6 K/9 in first 8 GS. AA has to be on the horizon.

13 John Lamb KC SP A- Left last start due to elbow discomfort. Doesn't sound serious, but check back frequently.

15 Danny Duffy KC SP B+ There will be bumps, but he may already be KC's top starter.
