One Pirate makes the list, Jameson Taillon at 18. Video on Taillon here.
The Royals lead the way with 6 players followed by the Rays with 4. In the division Cincinnati has 3 (6. Aroldis Chapman, 45. Devin Mesoraco, and 49. Yonder Alonso), the Cubs have 1 (46. Brett Jackson), the Cardinals have 1 (20. Shelby Miller), the Astros have 1 (Jordan Lyles), and the Brewers have 0. The Brewers and Cubs each traded a top 50 prospect (37. Jake Odorizzi and 47. Chris Archer) in the last few weeks. No NL Central players appear in the 51-60 list either (though Miguel Sano does).
