Mike Bolsinger suffered his first loss of the season, but is still the man to own for fantasy baseball team owners. Bolsinger is sporting an astonishing 1.15 ERA over 31-plus innings in five starts. He has 25 strikeouts against only 9 walks, but there are serious concerns about his velocity.
Bolsinger’s fastball doesn’t even touch 90 MPH on the radar gun. On average his fastball hits 86 MPH with his changeup at 83 MPH and curveball at 80 MPH. History will tell you that this lack of ball speed has to catch up with you and the losses will follow.
His contact rates are also high, which will eventually lead to balls finding gaps. This doesn’t mean he won’t have sustained success, just not to the level he’s set thus far this season. Bolsinger should hold down a spot in your starting rotation, but beware of the regression to come.
