Travis Sawchik explores Corey Kluber‘s strikeout run. Kluber is using his breaking ball more as his out pitch, because batters don’t adjust:

“I’m not sure it’s as much me doing anything differently as much as it is guys just don’t care about striking out,” Kluber said. “Batters used to believe striking out was a bad thing. They changed their approach with two-strikes, shortened up.”

“I think it goes hand-in-hand,” said Kluber of his breaking ball usage and strikeout rate. … Guys a lot of times don’t really make adjustments. They go up there swinging for the fences. More times more than not [the breaking ball] is the best pitch to take advantage of that.”

Just because they haven’t adjusted yet doesn’t mean they won’t adjust. Some smart manager with players who listen will get the point across to look for the breaking ball with two strikes.
