Tarik Skubal's remarkable journey to becoming the MLB's most coveted arm is a testament to the power of innovation and the evolution of pitching strategies. His story is a fascinating blend of personal determination, mentorship, and the application of cutting-edge technology in baseball.
Skubal's transformation began with a simple yet crucial realization: the need for an effective changeup to counter right-handed hitters. This realization led him to embark on a journey of experimentation and refinement, guided by the expertise of coaches like Doug Bochtler, Chris Fetter, and Robin Lund. The key to his success lay in mastering the 'seam-shifted wake' effect, a concept that revolutionized his changeup's movement.
The 'seam-shifted wake' phenomenon, as explained by Skubal, refers to the aerodynamic force that makes a baseball's seams influence its movement. By understanding and harnessing this effect, Skubal's changeup became a devastating weapon, generating down-and-away movement and a high whiff rate. This transformation is not just about Skubal; it's a broader trend in baseball.
The usage of changeups has been on the rise, with a significant increase from 10.3% of pitches last season to 11.1% this year. This surge in changeup usage is backed by impressive statistics. Batters are hitting at lower averages (.224) and slugging percentages (.349) against changeups, while the whiff rate is near its highest. The movement of these pitches has become far more pronounced, with the average changeup moving 14.1 inches side to side, up from 12.4 inches in 2016.
This evolution is not just about the mechanics; it's also about the data. Statistical models now provide a clearer picture of the effectiveness of changeups, leading to a more strategic approach to pitching. Pitchers like Jacob deGrom and Cristopher Sánchez have thrived with their changeups, with deGrom's whiff rate on changeups reaching a staggering 43.6%.
The rise of changeups is also a response to the cat-and-mouse game between hitters and pitchers. As sweepers, which are essentially sliders with massive horizontal movement, became popular, hitters adjusted. This led to a shift in pitch usage, with changeups becoming more prevalent and effective.
The impact of changeups is evident in the careers of pitchers like Skubal and Sánchez. Skubal's changeup has become a game-changer, propelling him to the top of the trade market. Sánchez, on the other hand, has mastered a unique grip, throwing his changeup with his index finger off the ball, giving it a distinct deadening effect.
The trend of changeup usage is not just a fad; it's a scientific and strategic evolution. More pitchers are embracing 'kick' changeups, a new pitch design that involves spiking the middle finger to create a devastating tumbling effect. This trend is reflected in the increasing number of pitchers using changeups at least 25% of the time, with 28 pitchers already meeting this criterion in 2026.
In conclusion, Tarik Skubal's success with his changeup is a testament to the power of innovation and mentorship in baseball. The evolution of changeups from a change-of-pace pitch to a power pitch is reshaping the game, and pitchers like Skubal are at the forefront of this revolution. As the sport continues to evolve, the mastery of changeups will be a key factor in determining the success of pitchers across the league.
