Tuesday, 7:05 PM – Vance Worley
Worley’s fastball sits around 89-91 MPH and can touch as high as 94. He throws both a four-seam and a two-seam fastball at that velocity. He goes to his 84-86 MPH slider fairly often and also throws an occasional curveball in the mid 70′s. Neither pitch misses many bats, but both lead to plenty of ground balls. Worley experimented with a new split-fingered pitch this spring to replace his mid 80′s circle change, but it appears he has mostly scrapped the changeup entirely in 2012. Brooks Baseball has him throwing 15 changeups on the season, all against lefties. Worley’s stuff has been pretty hittable thus far in his limited time in the majors. He is missing a lot more bats with the fastball this year, but is still really struggling to fool opposing hitters with his secondary stuff.
