Cal Raleigh's 2025 season was a historic achievement, but his 2026 performance has left fans and analysts alike perplexed. Despite an impressive bat speed and pulled air-ball rate, Raleigh's home run production has taken a hit, leaving many to question what's gone wrong. The answer lies in a combination of factors, including a disjointed season marked by an oblique injury and a shift in swing decisions and timing. The Mariners' GM, Justin Hollander, believes that Raleigh's injury affected his physical and mental state, leading to a widening of his swing distribution and a decline in contact quality. This is further evidenced by Baseball Savant's new metrics, which highlight a decrease in 'Perfect Swing' rate and an increase in 'Flawed Swing' rate. Driveline Baseball's analysis supports this, showing a spread in swing timing distribution, particularly against fastballs. The issue is most apparent against high-velocity fastballs, where Raleigh's average, slugging mark, and wOBA have all suffered. This change in contact depth is significant for a pull-side power hitter, as it can mean the difference between a home run and a flyout. The story of Raleigh's season is one of slight adjustments and a return to form. His performance on pitches outside the strike zone has cratered, and he's chasing more pitches than before. However, the underlying indicators suggest that Raleigh hasn't lost the traits that produced his breakout 2025 season. The Mariners' GM, Justin Hollander, believes that Raleigh's performance will improve as he gets more reps and finds his rhythm again. In my opinion, Raleigh's season is a testament to the fine line between success and failure in baseball. It's a reminder that even the best players can struggle, and sometimes it's just a matter of a few inches deeper at contact or a fraction of a second later on fastballs. I think that Raleigh's ability to adapt and make adjustments will be key to his success moving forward. As he continues to work through his issues, I'm confident that he'll find his rhythm and return to his dominant form.
