Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2025, Thyago Vieira threw 1,964 pitches that were tracked by the PITCHf/x system between 2017 and 2024, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2024, they relied primarily on their Sinker (97mph), Slider (88mph) and Fourseam Fastball (97mph). He also rarely threw a Change (92mph).
In 2024, compared to other RHP:
Their sinker is thrown at a speed that's borderline unfair, generates a high number of swings & misses compared to other pitchers' sinkers and results in somewhat more flyballs compared to other pitchers' sinkers. Their slider is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' sliders and has primarily 12-6 movement. Their fourseam fastball is blazing fast. Their change (take this with a grain of salt because they've only thrown 6 of them in 2024) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
