Diaz's overall numbers bounced back in a monstrous way last season. He dropped his ERA from a bloated 5.59 in 2019 to a 1.75, and upped his strikeout rate to a career-best 45.5%. He was among the league leaders in nearly every expected statistic (batting average, slugging percentage wOBA, and ERA), and he cut his HR/9 rate from 2.33 to just 0.70. Diaz's walk rate actually regressed, however, as he issued free passes to nearly five batters per nine innings. That's not often a recipe for success from a closer, but Diaz can survive at that rate if he continues to keep the strikeouts up and limit the long balls. In the end, Diaz does carry some risk given his history, but he should be drafted as one of the upper echelon closers in the game, if not a touch behind the truly elite options.
