JoJo Romero has thrown 4,059 pitches that have been tracked by the PITCHf/x system between 2020 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Sinker (93mph), Slider (82mph) and Change (87mph), also mixing in a Fourseam Fastball (93mph).
In 2026, compared to other LHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo and has slight armside run. Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and results in more flyballs compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 17 of them in 2026) is thrown extremely hard, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 4 of them in 2026) is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo.
