Cardinals right-hander Lance Lynn allowed a pair of homers in an otherwise decent June 6 start against the Blue Jays, in Toronto, and was apparently convinced afterward that he’d been tipping some of his pitches.
Derrick Goold of the St. Louis Post Dispatch described how Lynn and the coaching staff noticed and then fixed the issue:
The hitters’ reaction to his breaking ball was telling, and to combat their read on him Lynn changed the positions of his hand. He’d been more consistent from the stretch, so he lowered his hands from the windup, too, and “stopped the up-down motion.” The benefit has been an increased command of his fastball and less wild, untamed movement from his sinker. His curveball has also been more effective.
Last night Lynn tossed eight shutout inning against the Rockies, at Coors Field, and since that June 6 start against the Blue Jays he’s thrown 22 innings with a 0.82 ERA and 20/4 K/BB ratio.
