Non-MLB
Oscar Nakaoshi has thrown 125 pitches that have been tracked by the PITCHf/x system between 2025 and 2026, all of them occuring in The World Baseball Classic. In 2026, they have relied primarily on their Fourseam Fastball (86mph), Change (81mph) and Slider (81mph).
In 2026, compared to other LHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 14 of them in 2026) comes in below hitting speed, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has slight armside run. Their change (take this with a grain of salt because they've only thrown 14 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and results in many more groundballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 12 of them in 2026) is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement.
