Although he has not thrown an MLB pitch in 2020, Alex Claudio threw 4,586 pitches that were tracked by the PITCHf/x system between 2014 and 2019, including pitches thrown in the MLB Regular Season, the MLB Postseason, The World Baseball Classic and Spring Training. In 2019, he relied primarily on his Sinker (86mph) and Change (74mph), also mixing in a Slider (77mph).
Basic description of 2019 pitches compared to other LHP:
His sinker is so slow that it is substantially gravitational, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has slight armside run. His change comes in below hitting speed, has an obvious armside fade, dives down out of the zone and generates a very high amount of groundballs compared to other pitchers' changeups. His slider comes in below hitting speed, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders.
