Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Tyler Olson threw 1,610 pitches that were tracked by the PITCHf/x system between 2015 and 2019, including pitches thrown in the MLB Regular Season and Spring Training. In 2019, they relied primarily on their Cutter (87mph) and Curve (73mph), also mixing in a Change (81mph). He also rarely threw a Sinker (88mph).
In 2019, compared to other LHP:
Their cutter has heavy sink, results in somewhat more groundballs compared to other pitchers' cutters and has strong cutting action. Their curve has sweeping glove-side movement, results in somewhat more flyballs compared to other pitchers' curves and has slightly below average velo. Their change is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action and dives down out of the zone. Their sinker (take this with a grain of salt because they've only thrown 8 of them in 2019) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has slightly below average velo.
