2025 Player Outlook

Diaz converted 28-of-32 save opportunities last season with a 3.99 ERA (4.57 FIP) and 1.30 WHP. His 22.7 percent strikeout rate was a significant drop from past seasons, as was his 25.8% O-Swing%, 11.0% SwStr, and he allowed a career-high 76.3 percent contact rate. His slider is his best weapon, but when he falls behind, he leans on his fastball, which isn’t his swing-and-miss pitch, and he posted the worst first pitch strike rate of his career last year (54.1%). The Reds will head into the season with Diaz as its closer, but the strikeout rate must rebound, and the ERA get closer to 3.00 for him to be a top-10 fantasy closer in 2025.
