Oh... and the pitcher has thrown 4 COMPLETE GAME SHUTOUTS IN HIS LAST 7 STARTS... Three 3-hitters and a 2-hitter!
Most of you should have guessed the prospect by now... but my next question is... would you consider him among the Top 100 prospects in baseball?
Compare those numbers with those of other control artists like Jeremy Sowers and everyone's new favorite Kevin Slowey. What makes them "top pitching prospects" while the guy mentioned here doesn't even get an honorable mention?
