Kepler's approach is, and always has been, good. It's quite baffling that he doesn't hit for a higher average because of that. Some of that is trying to hit into the shift, but that can't be all of it. Weak contact adds to that.
One thing that I noticed in Sunday's game is that you could see him trying to go up the middle or to leftfield. If he's going to have any sustainable success, he's got to use all fields more. Add in harder contact and he can be more like the hitter he was 2019.
