Wednesday, 1:35 PM – Dallas Keuchel

Keuchel has made only three major league starts, so he has precious little PITCHf/x data available. He is a left-handed pitcher who relies on command and deception to compensate for his unimpressive raw stuff. His fastball sits around 87-88 MPH and he throws a sinker with decent arm-side movement. He has a pretty deep arsenal and mixes his pitches well. His best secondary offering is a mid 70’s changeup that he appears to command pretty well against lefties. The changeup is the only pitch Keuchel has been able to miss bats with so far in the big leagues, as his other offerings have been extremely hittable. He also throws a slow 70-73 MPH curveball and a mid 80’s cutter. Unsurprisingly, Keuchel has allowed a ton of contact but has kept the ball on the ground since his promotion to Houston.

Sounds like the second coming of Paul Maholm.

Ian Rothermund

Paul had a better fastball when he came up. It’s almost as if, as time went by he resigned himself more and more to simply being that soft tossing lefty. Early on though, I remember him getting angry in some different situations and hitting 93-94 with regularity.
