Kazmir = .253/.353/.533 in 15 ABs
Saunders = .500/.556/1.250 in 8 ABs
Santana = .500/.500/1.167 in 6 ABs
Burnett = .381/.435/.619 in 21 ABs
Joba = .500/.583/.900 in 10 ABs
Pettitte = .435/.500/.625 in 32 ABs
Halladay = .278/.316/.667 in 18 ABs
My guess would be that his upside lies in his not having many ABs against AL pitchers yet.
