1. EMMANUEL CLASE
For those of you who have qualms in Clase being at our top spot: In his career, he has allowed an OPS under .500 against 1,200 hitters. To put that into perspective, no other pitcher in MLB history has allowed an OPS under .500 that’s faced at least 500 hitters!
2. MASON MILLER
Last season, Miller threw 510 pitches over 100 mph last season. That’s more than every other team in baseball combined.
3. DEVIN WILLIAMS
Not only was he the one to vanquish the Yankees facial hair policy. His .144 BAA (batting average against) is the best among relievers since 2020. He also has the second highest strikeout rate at 40.8% during that span. And this spring, to compliment his air bender he added 2+ inches of induced vertical break to his fastball.
4. JOSH HADER
In 2024, Hader threw his slider 328 times that netted the highest slider whiff rate at 60.2%.
5. RYAN HELSLEY
The Cardinals record last season was 83-79. They were 59-6 in the games that Helsely pitched.
6. EDWIN DIAZ
In the second half of 2024, Diaz finished with the highest K% among all relievers with 44.3%
7. ANDRES MUNOZ
None of his three primary pitches (slider, fastball, and sinker) had a BAA over .172, an xBA over .210, SLG% over .345, and an xSLG over .375 last season. (credit to @LouisAnalysis on X)
8. FELIX BAUTISTA
In 2023, Bautista’s fastball had a 123 tjStuff+ which was the highest ever recorded. To put that into context, Mason Miller’s fastball had a 118 tjStuff+ last season. (credit to @TJStats on X)
9. JHOAN DURAN
Earlier this spring he became the first pitcher in MLB history to throw an off-speed pitch (splitter) at 100 mph.
10. RYAN WALKER
Finished with a 63.8% rate of getting a two-strike count against 308 batters. That was the second highest rate (against a minimum of 300 batters) to only Blake Snell (64.1%). (credit to Jon Anderson @JonPgh on X)
