Mattia Sireus has thrown 3 pitches that have been tracked by the PITCHf/x system in 2026, all of them occuring in The World Baseball Classic. In 2026, they have relied primarily on their Sinker (91mph) and Curve (72mph).
In 2026, compared to other RHP:
Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2026) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly below average velo. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2026) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has a sharp downward bite.
