Houston Astros
Kai-Wei Teng has thrown 4,698 pitches that have been tracked by the PITCHf/x system between 2023 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 Slider (85mph) and Fourseam Fastball (94mph), also mixing in a Sinker (94mph), Change (88mph) and Curve (84mph).
In 2026, compared to other RHP:
Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball has some natural sinking action, has slight armside run and has slightly above average velo. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, results in many more groundballs compared to other pitchers' sinkers, has well above average velo, has slight armside run and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 18 of them in 2026) dives down out of the zone, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2026) is thrown extremely hard, has sweeping glove-side movement and results in more flyballs compared to other pitchers' curves.
