Pitchers Boost Velocity in 2026, Raising Questions About Performance and Health The 2026 Major League Baseball season has seen a notable surge in fastball velocity, with the average four-seam fastball clocking in at 94.6 mph through early April. This marks a significant jump from the 91.9 mph average recorded in 2008, when pitch-tracking technology first became widely used. Similarly, sinkers have gained speed, averaging 93.9 mph this season compared to 90.7 mph in 2008. While velocity has long been a focal point for pitchers, the 2026 season highlights how improvements in speed are reshaping performance and health outcomes for several key players. Shota Imanaga, the Cubs’ left-handed starter, has emerged as a standout example of how velocity can rebound after injury setbacks. Imanaga missed nearly two months of the 2025 season with a left hamstring strain, which led to a drop in his fastball velocity. His four-seamer averaged 90.7 mph during his final 17 starts of the year, down from his rookie season average of 92.1 mph. This decline contributed to a down year, as his fastball became his least valuable pitch, with a run value of -10. However, Imanaga has since rebounded, carrying over his Spring Training velocity bump into the 2026 season. Through April 6, his four-seamer averaged 92.2 mph, a +1.4 mph increase from 2025. The improvement has translated to tangible results. Imanaga has thrown 12 pitches at least 93 mph this season, a stark contrast to just 13 such instances in 2025. In his April 3 start against the Guardians, his fastball sat at 92.6 mph in the fifth inning, matching his pre-injury velocity. Imanaga acknowledged the importance of velocity, stating, “For me, velo isn’t everything, but obviously, having velocity is an advantage.#major_league_baseball #cubs #marlins #shota_imanaga #janson_junk
