John Sickels lists his sleeper picks:
Michael Blanke, C, Chicago White Sox …
Andre Rienzo, RHP, Chicago White Sox …
Tyler Saladino, SS, Chicago White Sox
Rienzo is an SBT favorite. Here are some recent updates on him:
Intriguing sleeper…report contains a breakdown of his mechanics, which are pretty Tim Lincecum-esque
Rienzo uses a low-mid 90s fastball to key a relatively well-developed three-pitch repertoire. He carries his velocity deep into games, and looks like a potential back of the rotation starter.
Rienzo flashes pretty decent stuff, featuring a mid 90s fastball and developing offspeed stuff. Along with this, Rienzo has displayed pretty decent control.
