Paul Skenes’s Struggles Can Be Traced to a Slight Windup Change

This article was originally published as part of Verducci’s View, a weekly baseball newsletter from Sports Illustrated senior writer Tom Verducci. Every Monday, Tom empties out his notebook over email and covers MLB’s hottest topics, provides in-depth analysis through both text and video breakdowns, looks forward to what’s worth watching during the week and more.

Breakdown of the Week

What’s wrong with Paul Skenes? In 11 starts since June 9, he is 3–5 with a 5.28 ERA. The Pirates are 3–8 in those 11 starts.

June 9 was the day Skenes adjusted his stride to be less crossfire than ever before. Notice the difference in his feet position (more direct to the plate) and hand position (less offset) in these back-to-back starts:

He has become even more direct since June 9. By not stepping across his body as much, Skenes is releasing the baseball with 8–9” less offset (from the center line of the plate). The effect of a lesser horizontal attack angle is particularly obvious against right-handed hitters:

Through June 8 -2.67 .193 .307
Since -2.18 .301 .470

For a more detailed look at what’s going on, check out the breakdown above. This graph shows how Skenes’s slump coincides with the sudden change to his stride direction and release point, which has never been this direct in his career:
