Guardians Analysis: Cutter Inc.

Corey Kluber is no stranger to Cleveland. After José Ramírez, there isn’t a player with fabrics tied more tightly to the city and its baseball team in the 2010’s than the two-time Cy Young winner. Kluber was always on the cutting edge of pitching mechanics, and what separated him from the rest was fastball and breaking ball diversity.

It also helped that everything he threw was flat out nasty. Now back in Cleveland as an advisor and occasional face in the clubhouse, Kluber’s fingerprints are all over the Guardians’ rotation, more specifically through the cutter. BIG RIG Gavin Williams is someone who I’ve covered extensively on CtC.

I forecasted his breakout last season around the end of May after a rough start forced him to integrate his cutter and prominently feature it in his arsenal. Last season, Gavin’s cutter was essentially a deadened four-seamer. What that means is he kept a similar grip but applied more pressure on his middle finger, killing the arm-side movement on the offering.

This was vital to Gavin’s success as his fastball, while playing at a high level at the top of the zone, wasn’t finding the zone enough, and he had no secondary heater to get ahead in counts. Williams led baseball in walk rate in 2025, but the ever growing confidence in the cutter both dropped the walk rate slightly and allowed Gavin to find more success in the zone with his fastball. His heater went from a 15.
