A barely-there piece of the arsenal and even then, almost exclusively against LHB, Lopez’s change was used 3.2% of the time overall in 2019 which was actually almost double the rate he used it in 2018. It shows below-average movement and Lopez has not shown the ability (or desire?) to throw it for strikes with a 18% zone rate and 22.2% chase rate.
Yoan Lopez’s excellent velocity (96.3 mph) hasn’t translated to strikeouts to this point in his career. Overall the pitch comes out pretty straight with much less tail and a bit more sink than the average fourseamer, and as a result allows the ball to be hit in the air 59% of the ime and a 26.3% HR/FB rate which netted a .861 OPS and .265 ISO against in 2019.
Used 39.4% of the time, Lopez’s only breaking ball shows good horizontal glove side movement with average drop and a 12 mph velocity separation from his fourseamer. As his goto strikeout pitch, it successfully gets the K on 27% of its usage with 2 strikes and was responsible for 26 of Lopez’s 42 strikeouts in 2019 despite not getting elite chase rates (35.1% O-Swing).
Lopez’s primary pitch had an average velocity of 97.1 mph and featured just a touch of arm-side movement. While the pitch did have a 52.3 Zone%, it only had a 12.2 O-swing% and 8.1 SwStr%, which doesn’t really back up his 26.1 K%.
Lopez’s slider came in at 84.1 mph, so batters expecting the 97 mph heat were left flailing away. The pitch had a 45.0 Zone%, 40.9 O-swing and 15.0 SwStr% while also sporting a 40.0 K%.
