2025 Fantasy Outlook
Agnos will compete for a spot in the Rockies' bullpen this spring. Colorado has no shortage of high-end relief pitching prospects, with Seth Halvorsen and Jaden Hill impressing in the big leagues late last season, but Agnos is right up there with them from a stuff standpoint. He boasts a mid-to-upper-90s four-seam fastball, a low-90s cutter, a slider and a splitter and has saved 44 games in the minors over the past two seasons. The 24-year-old righty logged a 1.95 ERA, 0.87 WHIP and 33 strikeouts in 27.2 innings at Double-A Hartford last year. Halvorsen is the Rockies reliever of the moment in fantasy, but there is a path for Agnos to be the team's closer by the end of 2025. Read Past Outlooks

ANALYSIS
The right-hander was unable to secure a spot on Colorado's Opening Day roster but will get his first taste of the majors as Victor Vodnik (shoulder) heads to the injured list. Agnos posted a 1.38 ERA and 63:11 K:BB across 52.1 innings between the High-A and Double-A levels last year, and he's continued to pitch well at Triple-A early in 2025. He's recorded 46 saves during his minor-league career but will likely need to work his way into a high-leverage role for the Rockies.
