Coby Mayo hits the baseball hard. Freakishly hard. The difference now is that he is starting to do it consistently at the major-league level.
As the Orioles’ playoff hopes continue to dwindle, there will be plenty of blame to go around if they miss the postseason. The front office, players, coaches and even player development will all face criticism.
Mayo’s development, however, should not be viewed as one of those failures.
Behind Pete Alonso’s historic signing and Samuel Basallo’s rise, Mayo’s continued growth has been one of the more encouraging developments of the 2026 season. Now, the numbers are not perfect, and there are still major areas for improvement, but the underlying tools are impossible to ignore.
Maximum exit velocity and average exit velocity are two of the strongest indicators of a hitter’s raw offensive potential. Almost every great hitter in Major League Baseball ranks highly in one or both of those categories. Exit velocity is not everything, but the ability to consistently hit the baseball hard is a big piece of what makes great hitters great.
Against left-handed pitching, Mayo has been one of the Orioles’ most dangerous bats. However, there are still clear concerns in his profile, as he currently owns a .280 on-base percentage while striking out at a 32.8% clip. That strikeout rate ranks in the bottom three percent of Major League Baseball, which is clearly not good enough.
However, Mayo ranks in the 99th percentile in maximum exit velocity and the 90th percentile in average exit velocity. Those are rare numbers, and they suggest that underneath the strikeouts is the foundation of a potentially elite hitter.
That brings us to one of the biggest breakout hitters of the 2026 season: Jordan Walker. The former St. Louis Cardinals top prospect found himself in an almost identical situation to Mayo just one year ago.
Walker in 2025: .278 OBP / 31.8% K% / 7.3% BB%
Mayo in 2026: .280 OBP / 32.8% K% / 7.0% BB%
The surface numbers are strikingly similar. However, beneath Walker’s disappointing 2025 production was the same trait that now makes Mayo so intriguing: elite contact quality.
Walker ranked in the 99th percentile in maximum exit velocity and the 91st percentile in average exit velocity. Mayo currently sits in the same 99th percentile in maximum exit velocity and just one percentile behind Walker in average exit velocity.
Walker has developed into one of the more dangerous hitters in the sport this season. He shocked the baseball world by winning the Home Run Derby and has put together the best season of his young career, hitting 27 home runs with an impressive .845 OPS in 129 games played.
Coby Mayo is far from being a finished product. But if he can learn to limit the strikeouts, there is no reason he cannot become a perennial 30-plus home run hitter in this league.
Do not worry, Birdland. Mayo will have us covered.
