Kelvin Herrera was dreadful in his first season with the Chicago White Sox and that will need to change in 2020.
Herrera, 30, was just terrible during his first season in the South Side and there’s no way around that. Across 57 appearances in 2019, the right-hander had a 6.14 ERA, 4.58 FIP, 1.617 WHIP, 9.3 K/9, and 4.0 BB/9.
The good news is that there are actually some relatively promising trends in that, believe it or not.
His strikeout rate was actually the third-highest of his career while his FIP was 1.
