Just a quick PITCHf/x review of your 2010 AL Rookie of the Year. The three graphs below show the spin deflection (from the catcher's perspective) for Feliz pitches, both the full scatterplot and aggregated values, and the velocity distribution for the pitches. (click to enlarge)

Spectacular fastball (it says four-seamer here, but there may be some two-seamers thrown in as well). The slurve isn't bad, either.
Congratulations to Neftali!
