2026 Projections
2026 Fantasy Outlook
Keller maintained a familiar stat line in 2025, posting a 4.19 ERA and 1.26 WHIP across 176.1 innings. He's now posted a 4.19 and 4.25 ERA and between a 1.25 and 1.30 WHIP in each of the last three seasons. Already unspectacular, there are warning signs that things could get worse in 2026. Keller went through a much-publicized and successful effort to increase his velocity a few seasons ago, but those gains dissipated as he averaged only 94.0 mph with his fastball in 2025. His strikeout rate took a corresponding dip to 20.0 percent, his lowest mark since 2022. That leaves Keller as a volatile option, reliant upon soft contact and the defense behind him for per-start success. The biggest reason for optimism regarding Keller's fantasy value is that he throws bankable innings and is one of the safer bets to reach 175 innings pitched. Fantasy managers have almost certainly already seen the best that Keller has to offer, but he's a reasonable back-end starter in deeper formats, and more of a streaming option based on matchups in shallower leagues.
