Garrett Whitlock poised for reliable 2026 after dominant 2025 bullpen return

Garrett Whitlock is expected to remain a reliable reliever for the Boston Red Sox in 2026 after a dominant 2025 season in the bullpen, where he posted a 2.25 ERA in 62 appearances and didn't allow an earned run from August 19 onwards. Known as a strike-throwing machine, his sinker, slider, and changeup all boast strike rates over 65%. He was effective against both lefties and righties, holding them to an OPS below .600, and maintained a 30% strikeout rate.
