Corbin has made at least 31 starts in each of his four full seasons with the Nationals, which does hold some value for a team which has spent much of that stretch in a rebuilding phase. Unfortunately, the results were awful again in 2023, with the left-hander's 5.20 ERA and 1.48 WHIP ranking 42nd and 44th, respectively, among 44 qualifiers. Corbin had a 30.8 percent strikeout rate in his final season with the Diamondbacks, which is a large reason why the Nationals gave him $140 million. In 2023 that number tumbled to 15.7 percent, which also ranked dead last among qualifiers. Corbin has averaged 32.3 home runs allowed per season over the last three years, and his slider, which used to be one of the better pitches in baseball, had a .354 xWOBA last year. The southpaw is mercifully entering his walk year in 2024, which means the Nats might not even feel obligated to keep him in the rotation all season if things continue to go this poorly.
