The progress is both music to manager Joe Maddon's ears and also development that he believed would come in due time.
"He's maturing," Maddon said on the Laurence Holmes Show on Tuesday. "He's maturing in the batter's box. His setup, I'm liking it even better. He's more handsy, he's keeping the body out of it. It's a beautiful thing, and as long as he maintains this method, he can sustain this for a bit."
The next step for Schwarber is to keep his form going consistently when the Cubs face more left-handers, Maddon said. That hasn't been a trouble in 2019, as Schwarber has posted an .896 OPS against lefties and a .796 OPS against righties. His success against lefties is a marked improvement over his career numbers against them, as Schwarber has a .649 OPS over parts of five MLB seasons against southpaws.
"He's not missing his pitch," Maddon said. "I think he's putting himself in better position to not miss his pitch ... Really good hitters don't miss their pitch often -- they don't foul it off, they don't take it. And more recently, he's not been fouling it off and he's not been taking it."
