The last couple of seasons have been a struggle for Doolittle, a relief pitcher who, not all the long ago, was one of the best in the game. In 2018, his first full season with the Nationals, he was an All Star, pitching 45 innings of 1.60 ERA ball, with a 10 K/BB ratio to boot. In a word, he was fantastic.
2019 and, in particular, 2020, were struggles for Doolittle, however. Our own Tony Wolfe has taken dives into the reasons why over at Fangraphs in late 2019, and then again here at Red Reporter at the time of signing.
