Tyler Mahle held opposing hitters to a .298 slugging percentage and a meager .259 wOBA in all games pitched outside of the bandbox that is Great American Ball Park in 2021. Among the 127 Major League Baseball pitchers who threw at least 50 innings in away ballparks last season, just five managed to post a more dominating wOBA than did Mahle, and that group is something of a who’s who of MLB pitching: Corbin Burnes, Brandon Woodruff, Max Scherzer, Charlie Morton, and Walker Buehler.
That’s it.
Mahle, just 27, has a pair of seasons of relatively cheap team control left at the moment, his arbitration salaries (under the current model) expected to top out at around $15 million for those two years combined.
