Los Angeles Angels
Robert Stephenson has thrown 6,426 pitches that have been tracked by the PITCHf/x system between 2014 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Cutter (87mph) and Fourseam Fastball (97mph).
In 2025, compared to other RHP:
Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink and is an extreme flyball pitch compared to other pitchers' cutters. Their fourseam fastball (take this with a grain of salt because they've only thrown 13 of them in 2025) is blazing fast, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers and has slight armside run.
