Sunday, 2:20 PM – Chris Volstad
Volstad’s four-seam fastball sits around 89-92 MPH and is fairly straight. His two-seamer comes in at a similar velocity with good sinking movement. His 83-86 MPH changeup also has good downward break. He throws two breaking balls, an 82-85 MPH slider and a 78-80 MPH curve. All of Volstad’s pitches are very hittable, particularly so in 2012. Only the slider misses bats on occasion. However, other than the four-seamer, all of his pitches generate a good number of ground balls. His strikeout rate has fallen to a career worst and dangerously low 12.6%, which has made it difficult for him to limit base runners.
