A 10th-round pick in the 2022 MLB draft, Agnos has a 5.48 ERA across 21.1 innings. He has only 12 strikeouts, but has saved four games for the club.
The lack of strikeouts is certainly surprising, since he has an 11.2 K/9 ratio in the minor leagues.
He performed well during his time at Triple-A with a 2.25 ERA across 12 innings with 14 strikeouts.

In a corresponding move to make room for Agnos on the roster, Colorado has decided to option Angel Chivilli back to Triple-A.
He had made 25 appearances thus far for the Rockies, pitching 35 innings with a 5.91 ERA and -0.2 bWAR.
Chivilli was excellent in the minor leagues in 2024 between Double-A Hartford and Triple-A Albuqurque but has yet to be able to produce at the same level in the Major Leagues.
