Jimmy Yacabonis has thrown 1,315 pitches that have been tracked by the PITCHf/x system between 2016 and 2019, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2019, he has relied primarily on his Fourseam Fastball (94mph) and Slider (81mph), also mixing in a Change (87mph).
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, has an obvious tail, results in many more groundballs compared to other pitchers' fourseamers and has slightly above average velo. His slider sweeps across the zone, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and has below average velo. His change (take this with a grain of salt because he's only thrown 11 of them in 2019) has an obvious armside fade, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
