Henderson Alvarez Throws 58 MPH Curve Ball
Miami Marlins starter Henderson Alvarez has nasty stuff. In the arsenal: a dominant fastball (average velocity, via FanGraphs: 93.6), low-80s slider and plus change-up. And occasionally, Alvarez will mix in a SLOW curve ball. He did so last night, retiring Cliff Pennington with a 58 MPH deuce.
