Luis Severino struggling with slider

His slider is one part of the problem. I’ve watched a few of his starts. What I noticed is his fastball location is off. He’s catching too much of the middle of the plate. To verify I looked at his fastball heatmaps on Baseball Savant. Here’s what I found:

Edit: Missed the labels somehow. On the left is Severino’s fastball before July 2nd; on the right is his fastball after July 2nd.

A slider, which isn’t breaking as much, mixed with a straight fastball, which is finding too much of the plate, is a bad combination.
