Los Angeles Angels
Although he has not thrown an MLB pitch in 2018, J.C. Ramirez threw 4,313 pitches that were tracked by the PITCHf/x system between 2013 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, he relied primarily on his Sinker (96mph) and Slider (89mph), also mixing in a Curve (79mph) and Fourseam Fastball (96mph). He also rarely threw a Splitter (91mph).
Basic description of 2017 pitches compared to other RHP:
His sinker is blazing fast. His slider is thrown extremely hard and has short glove-side cut. His curve is a prototypical pitch with few remarkable qualities. His fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has well above average velo and has slight armside run. His splitter (take this with a grain of salt because he's only thrown 7 of them in 2017) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and has movement that suggests a lot of backspin.
