I skimmed through the last several innings pitched. Estrada, Sanders, Burdi. Yykstra dykstra, those guys really have both velocity and nastry offspeed stuff. Burdi's sweeper had huge sweep.
Sanders had some big offspeed movement. Had some pitches that missed badly.
Burdi's only pitched ~20 pro innings over the past five seasons, so perhaps it's possible that after a few months at Iowa, perhaps he'll get a little more comfortable and perhaps the control will improve some?
