Colorado Rockies
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

Converts third save
PColorado Rockies
May 23, 2025
Agnos walked one in a scoreless and hitless inning to earn the save in Friday's 3-2 win over the Yankees.
ANALYSIS
This was Agnos' third save of the season, though it was his first since May 1 versus the Giants. Over his previous five appearances, he had allowed four runs (two earned) with a 6:1 K:BB, earning one hold. Agnos is in the mix for closing duties for the Rockies, but considering the team improved to 9-42 with Friday's win, save chances are unlikely to be frequent. He has a 1.29 ERA, 0.93 WHIP and 7:2 K:BB over 14 innings this season.
