The sinker was, by far, Treinen’s most thrown pitch (47.9%). Like his slider, the average velocity dropped (in this case 1.3 mph from 2018) and he reduced his LD% and GB% and raised his FB% (from 15% to 23.8%) with his HR/FB rising from 6.7% to 20%. Like the slider, his sinker’s Z-Contact rose (to 92.1%), but fortunately, in the case of the sinker, his zone rate dropped to 39.1%. It was a great pitch in 2018 with a .526 OPS, but that was his career outlier, with an .887 OPS in 2017 and an .825 OPS last year (with OPS marks in the .790s in his first three seasons). Clearly, the 12.1 pVAL sinker from 2018 was gone, with the pitch earning a -0.5 pVAL in 2019.
