A ground ball pitcher is a pitcher who can induce opposing batters into hitting ground balls. An average ground ball pitcher has a ground ball rate (GB%) of around 50%. A really good groundball pitcher has a GB% approaching 55%.
Baltimore Orioles free agent signee Andrew Cashner has a career GB% of 49%.
Cashner’s reputation of being a ground-ball artist — he has a career 49 percent ground-ball rate — played to form.
He induced six groundouts, forcing weak contact by working both sides of the plate with his sinker and slider, but also missed bats when he needed to by adding two swinging strikeouts.
I wouldn’t say Cashner is a ground ball artist. He ranked 24th last year in ground ball outs (204). I think he definitely has what it takes to pitch successfully at Camden Yards, a fly ball hitter’s park.
