Tuesday, 7:05 PM – Paul Maholm
Maholm’s bread and butter pitch is his 87-88 MPH sinker, which he goes to on nearly a third of his offerings. The pitch has plenty of horizontal tail to go along with the sinking movement, and has led to a ground ball on approximately 64% of balls in play in 2012. His four-seam fastball comes in a tick harder at 87-89 MPH, but he has only cracked 90 MPH a few times this season. Maholm has a deep repertoire, and he mixes his pitches well. He throws a 71-74 MPH curveball, an 80-82 MPH slider, a 79-83 MPH changeup and appears to have added an 83-85 MPH cutter over the past couple seasons. None of his offerings miss many bats, although the slider has been a solid swing-and-miss pitch at times over the years. However, the majority of his pitches generate well above average ground ball rates, allowing him to effectively limit damage on batted balls.
