#12 Jameson Taillon
Previous Rank: 14
The Pirates insist on babying Taillon, who some thought actually was the top player available in the 2010 draft even ahead of Bryce Harper. Regardless of who was better, what is certain is that Taillon was the best pitching prospect in his class, so some restraint is probably highly prudent and highly warranted.
His fastball and breaking ball are both at least 60-grades every night and can reach 70s. His breaking ball is arguably the best pitch from any of the last five drafts, and his fastball can reach the upper-90s with good plane and arm-side activity. His command can stand to improve, but it already has substantially since he signed.
Even though he never made it past the fifth inning of any start, he still was able to post a sub-4.00 ERA with 97 strikeouts and 22 walks in 92.0 innings. Look for that count to jump up to the 125 IP area in 2012 and for Taillon to dominate Double-A hitters like he did Sally League hitters. Taillon is so advanced in terms of stuff that he should never be challenged while in the Minors by anyone or anything except his own standards and the standards of his organization, which is quickly on the rise.
