Saturday, 4:10 PM – Chris Carpenter
(click to enlarge)
Carpenter does not have a very diverse repertoire. He pounds the zone with a sinking fastball that sits in the low 90’s and touches 95 MPH. He also throws a plus cutter in the upper 80’s and an above average mid 70’s curve. The cutter is his big swing-and-miss pitch, with a whiff rate just a touch under 30%. Both the cutter and fastball show strong sinking movement, which leads to his excellent ground ball rates. That ground ball rate is down a bit this year, but is still comfortably above average. Carpenter generally works in all four quadrants of the strike zone, making him even more effective.
Sunday, 2:15 PM – Kyle Lohse

Lohse is a soft-tossing right-hander with very hittable stuff. He throws a two-seam fastball that sits in the high 80’s and gets up into the 90-91 range at times. His best pitch is probably a circle change that sits around 80 MPH and generates an above average whiff rate. The rest of his pitches are regularly put into play. In fact, in 643 batters faced this year, his fastball has only led to about 27 swings-and-misses. Lohse also throws a low 80’s slider and mixes in an occasional slow curve. He generally works on the outer half of the plate, but will occasionally work inside on left-handers with the two-seamer.
