Logan Webb’s change-up was considered one of the best pitches in baseball in 2023. He threw more than 40% of the time and served as the horse he rode to a runner-up finish in the National League Cy Young voting. Its 28 Run Value was the second highest total of any pitch type across the Majors. Compared to other offspeed offerings, Merrill Kelly’s 16 RV was the next highest RV total.
In 2024, the dominance that we — and probably Webb as well — took for granted with his signature pitch disappeared. The change-up’s year end Run Value had dropped into the negatives, a rough plummet from the best in the league penthouse to the dark, dank cellar of the 14th percentile.
