The Pitching Lab: How MLB Arms Are Evolving
Major League Baseball is undergoing a pitching revolution. It’s not just about velocity anymore. it’s about deception, movement, and constantly adapting to stay one step ahead of hitters. Several pitchers are actively tweaking their arsenals, and the results could reshape the landscape of the game.
Devin Williams and the Return to Dominance
After a stellar 2024 with a 1.83 ERA, Devin Williams experienced a dip in performance in 2025, posting a 4.79 ERA. However, his underlying metrics suggest a potential rebound is on the horizon. Williams isn’t relying on luck; he’s proactively making adjustments. He’s revisiting pitches he’s used in the past – the cutter and gyro slider – to regain his edge.
Williams previously utilized a cutter primarily against left-handed hitters, and his changeup showed surprising effectiveness against the same batters. The reintroduction of these pitches, alongside his already potent changeup (used 45% of the time early in counts), could create more uncertainty for opposing hitters. The gyro slider, in particular, might be a key to unlocking his potential against right-handed batters.
The Rising Tide of Pitching Adjustments
Williams isn’t alone in this trend. Several other pitchers are actively working to refine their skills. Roki Sasaki, a highly touted prospect, is expected to transition back to a starting role, suggesting a focus on building stamina and expanding his pitch repertoire for longer outings. Garrett Crochet and other pitchers are as well experimenting with new approaches to maximize their effectiveness.
What Does This Mean for the Future?
The emphasis on continuous improvement and pitch refinement signals a shift in how pitchers approach the game. It’s no longer enough to simply throw hard; pitchers must be strategic, adaptable, and willing to experiment. This trend is likely to continue, with more pitchers embracing data-driven insights and personalized training programs to unlock their full potential.
Frequently Asked Questions
What is a gyro slider?
A gyro slider is a breaking ball with a unique spin axis that creates a distinct movement profile, often appearing to “spin” rather than break sharply.
Why are pitchers revisiting older pitches?
Pitchers are revisiting older pitches to add deception and keep hitters off balance. Introducing a new or previously rarely used pitch can disrupt a hitter’s timing and create more opportunities for strikeouts.
How important is data analysis in modern pitching?
Data analysis is crucial. Pitchers and coaches are using data to identify weaknesses in their approach and to develop strategies for maximizing their strengths.
Pro Tip: Pay attention to pitchers who are making subtle changes to their mechanics or pitch grips. These adjustments can often be indicators of a potential breakout season.
