I'll trust he knows what he's doing, but I will be highly skeptical and probably ready to pounce a few years down the road. Bllom started with the Rays in 2005, moved up in 2008 and became Director of Baseball Operations in 2011. He pretty much gained control in 2014, after Friedman left to LA.
It's hard to attribute this player or that player to Bloom or someone else, and most picks are consensus choices, but here are the Rays first picks since 2005 with the pick number in front:
8. Wade Twonsend
3. Evan Longoria
1. David Price
1. Tim Beckham
30. LeVon Washington
17. Josh Sale, 31. Justin O'Conner, 42. Drew Vettleson (2010)
24. Taylor Guerrieri, 31. Mikie Mahtook, 32.Jake Hager, 38. Brandon Martin, 41. Tyler Goeddel, 52. Blake Snell,, 56. Kes Carter, 59. Grayson Garvin, 60. James Harris (The famed 2011 draft where they had something like 11 of the top 80 picks and only chose one right: Snell.)
25. Richie Shaffer
21. Nick Ciuffo
29 Ryne Stanek (Still in the bigs)
20. Casey Gillaspie
13. Josh Lowe
4. Brendon McKay (2017- same pick we have, this year #4)
16. Mathew Liberatore
22. Greg Jones
24. Nick Bitsko
One thing about Bloom and his days with the Rays. Their draft picks were not their strong area, especially their first picks, but they may have chosen players not wanting big signing bonuses.
