2026 Fantasy Baseball Player Profile

Mitch Keller’s 2025 season was a study in reliable mediocrity, as the veteran right-hander further established himself as a durable, if unspectacular, "innings eater" for the Pirates. Appearing in 32 games, Keller posted a 4.19 ERA and 1.26 WHIP over 176.1 innings—marks nearly identical to his 2023 and 2024 campaigns. While his 6-15 record was more a reflection of poor run support than his individual performance, concern mounted regarding his "stuff"; his average fastball velocity dipped to 94.0 mph, and his strikeout rate fell to a three-year low of 20.0%. He notably struggled down the stretch, stumbling to a 5.56 ERA after the All-Star break as hitters increasingly punished his four-seamer.

The 2026 season represents a transitional year for the 29-year-old, who now serves as the veteran bridge between ace Paul Skenes and a wave of high-upside prospects like Bubba Chandler and Thomas Harrington. Entering the third year of his five-year, $77 million extension, Keller was the subject of persistent trade rumors this winter (linked to the Braves and Orioles), but he remains the rotation’s stabilizing force. He officially kicked off his 2026 spring training on February 22 with a dominant two-inning scoreless stint against the Rays, where he unveiled an "absurd" new-look changeup featuring a completely redesigned grip. The goal for 2026 is to utilize this new weapon to reclaim the swing-and-miss profile he possessed during his 2023 All-Star season.

For fantasy managers, Keller is the quintessential "safe" late-round target with an ADP around 320.
