Strengths: Gonzalez has a fundamentally sound delivery that he repeats well, creating effortless 92-95 mph velocity with his fastball. His low-80s hammer curveball always has been his go-to pitch, and he'll use it in any count. He located his changeup better in 2006, and it shows flashes of being a third plus pitch. Though there were questions about his durability, he pitched a career-high 155 innings and added 16 more in the Arizona Fall League.

Weaknesses: Gonzalez will need better command with his fastball and more consistency with his changeup to succeed at higher levels. He fell behind in the count early and often in Double-A, leading to too many homers and walks. He can get top-heavy in his delivery, which causes him to rush his lower half and leave fastballs up in the zone.

Gonzalez has a polished three-pitch repertoire that's highlighted by one of the minors' best breaking balls. He has great feel for and confidence in his two-plane curveball, which changes hitters' eye level and grades as a plus-plus pitch. He adds and subtracts from his fastball, which ranges from 86-92 mph and has occasional run and sink.

He also has feel for a changeup, which provides him with a legitimate third weapon. He has solid-average command, though he has a tendency to fall off the mound to the third-base side, causing him to miss his spots.
