Mitch Keller

Keller earned his first career All-Star nod in 2023 with a 3.31 ERA and 1.12 WHIP in 19 starts during the first half, but he fell apart after the break with a 5.59 ERA and 1.44 WHIP in 13 outings. The good news is that the right-hander stayed mostly healthy and set a career high with 194.1 innings, and he also improved his strikeout rate to 25.5 percent and walk rate to 6.7 percent. Keller also may have received some unfortunate results, as indicated by a 3.83 SIERA and 3.70 xFIP compared to a 4.21 ERA. Despite the struggles down the stretch in 2023, it's a season to build on as he enters his age-28 campaign. Keller certainly shouldn't be the ace of a staff but is a strong option to round out a rotation for fantasy managers in 2024, especially if he can maintain the decent strikeout and win (13) totals.
