Philadelphia Phillies
Seth Johnson has thrown 1,893 pitches that have been tracked by the PITCHf/x system between 2024 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (98mph) and Slider (87mph), also mixing in a Sinker (96mph) and Change (92mph).
In 2026, compared to other RHP:
Their fourseam fastball is thrown at a speed that's borderline unfair and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut, is much harder than usual and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 19 of them in 2026) generates a high number of swings & misses compared to other pitchers' sinkers, is blazing fast, results in many more groundballs compared to other pitchers' sinkers and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 15 of them in 2026) is thrown extremely hard, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
