If you took a look at this week's rankings and wondered where the 2011 draftees are, don't worry, I know there was a draft. It is my policy to not add guys to the prospect rankings until they sign a pro contract.

A brief preview of where I think guys will rank once they do ink contracts:

Gerritt Cole, PIT - Pirates #2 prospect, #20 ranked pitcher
Anthony Rendon, SEA - Mariners #2 prospect, #35 ranked hitter
Trevor Bauer, ARI - Diamondbakcs #2 prospect, #25 ranked pitcher

National League

11 Anthony Rizzo SD 1B A- 1.159 OPS in AAA has him reportedly in line for a callup this week. Grab him now.

16 Jonathan Singleton PHI 1B B+ Bat coming alive? .346 with 9 BB in last 8 games. Overall OPS juste .736.

20 Billy Hamilton CIN SS B+ Bat coming alive with 5 multi-hit games since May 30. Amazing 45 SB already.

22 Yasmani Grandal CIN C B+ Just 2 HR in 106 ab since April. .286/.407/.480 overall though.

25 Paul Goldschmidt ARI 1B B+ .458 with 2 HR through first 6 days of June. 1.0 EYE and ML-leading 19 HR.

17 Randall Delgado ATL SP B+ Mostly good in 12 starts but 10 ER in 1 of them has ERA at 3.51.

18 Rubby De La Rosa LAD SP B+ Solid start in a tough venue (PHI). 5 BB looked to be related to nerves.

19 Casey Kelly SD SP B+ I see him as a solid #3 starter in time. 4.07 ERA and 53:20 K:BB in 66.1 innings.

20 Zack Wheeler SF SP B+ Capped off May with a 7-3-0-0-1-12 effort. Impressive 3.40 ERA in tough pitcher's environment.

21 Arodyz Vizcaino ATL SP B+ 2.45 ERA in 9 GS got him the AA promotion. 13:4 K:BB in 13 innings there.

American League

4 Mike Moustakas KC 3B A Has OPS up to .835. No reason to call him up until he gets hot or Betemit slows down.

12 Wil Myers KC OF A- Just .261 in April, but far better lately. Just 2 HR in 81 at-bats though.

13 Brett Lawrie TOR 2B A- Bruised wrist has him sidelined, thus delaying promotion that was due. Won't be long though.

14 Jason Kipnis CLE 2B B+ Will need to go on a tear before Indians consider messing with the chemistry of the big club.

41 Nick Castellanos DET 3B B 5 BB in last 6 games suggests progress, but keep an eye on K:BB going forward.

6 Martin Perez TEX SP A- 1.47 ERA in 5 May starts. Remarkably polished for his age but no more than a Sept. callup - I think.

7 Manny Banuelos NYY SP A- 2.84 ERA, but not showing improvement in control - 5.2 BB/9 overall.

8 Jake Odorizzi KC SP A- Great, great start this year and kicks June off with a 6-3-0-0-2-8 effort.

10 Drew Pomeranz CLE SP A- 1.85 ERA and 12.0 K/9 through 9 starts and clearly ready to face AA hitters.

11 Dellin Betances NYY SP A- 1.99 ERA in 9 GS to go with 50:22 K:BB in 45.1 innings. Candidate for MLB time later this year.
