Bats: Right. Throws: Right
Rienzo is 24 years old and has reached the Double-A level and beyond in the White Sox organization. (He made one start at Triple-A last summer, where he pitched 6 2/3 shutout innings and struck out 10.) On the strength of a mid-90s fastball and effective changes of speed, his 2012 was impressive enough: 7-3 with a 2.53 ERA, a 1.16 WHIP and 113 strikeouts in 103 innings. But he also sat out a 50-game suspension for PED use last summer. The White Sox are prepping him as a starter, but his future might be in the bullpen.
