Notes: As a member of the Royals, Zack Greinke had a well-publicized internal battle within himself over his desire to play professional baseball, which was similar to what Duffy faced in 2010, temporarily walking away from the game in spring training. The lefty eventually found his way back and played at four levels in 2010, reaching double-A. At the highest level, he posted a 2.80 FIP in 39.2 innings while showing good control (2.04 BB/9). Duffy also posted a solid strikeout rate (9.30 K/9). He has a four-pitch repertoire that includes a 90-95 mph fastball, a changeup, curveball and slider. The lefty has a clean delivery and little effort. At worst, he should develop into a No. 3 starter, and should return to double-A to begin the 2011 season.
