Saturday, 7:05 PM – Carlos Zambrano
Zambrano’s velocity has slowly ticked downward over the past several years. At this point, his four-seam fastball sits around 88-90 MPH and occasionally touches the 93-94 range. He also throws an 89-91 MPH two-seamer with good sinking movement and an 88-91 MPH cutter. Against left-handed batters, he generally throws the two-seamer on the outer half and uses the cutter to tie up the inside corner. Zambrano uses a mid 80′s splitter as his offspeed offering, and does not hesitate to throw the pitch to right-handed hitters. His primary breaking pitch is a sweeping 78-80 MPH slider, and he also mixes in an occasional 68-71 MPH slow curve. In the past, Zambrano would throw from a variety of arm angles, moving from a straight over the top delivery all the way down to a three-quarters release point. However, he has mostly thrown from just the three-quarters angle this season. He does not really have a big swing-and-miss pitch these days, with most of his offerings generating a below average whiff rate. The curveball has been the lone exception this year, with a 2012 whiff rate around 40% in a very small sample. Overall, Zambrano’s stuff just isn’t nearly as impressive as it once was.
