From Josh Kalk’s Pitch F/X cards.
Kalk also runs similarity scores on his site for each pitcher and interestingly enough, Motte’s most comparable pitcher from 2008 was Grant Balfour. Balfour happened to lead the majors in K/9 with 12.65. Jason Motte led all of the minors in K/9 with 14.85. Both throw fastballs 90% of the time. So you tell me – can he get by with one pitch?
