Zach Agnos

The Rockies announced a flurry of bullpen moves this morning headlined by the club placing right-hander Victor Vodnik on the 15-day injured list due to right shoulder inflammation. Right-hander Zach Agnos was selected to the roster to replace him and will make his MLB debut when he first gets into a game. Meanwhile, left-hander Evan Justice was designated for assignment to make room for Agnos on the 40-man roster.

Vodnik, 25, made his MLB debut back in 2023 and emerged as an intriguing bullpen piece for the Rockies last year. He pitched to a 4.28 ERA in 73 2/3 innings, good for an above-average 110 ERA+ due to the fact that he calls Coors Field home. His 4.18 FIP was also slightly above bar when adjusted for ballpark, and he generated grounders at an impressive 54.4% rate that helped to make up for his lackluster 20.3% strikeout rate and inflated 11.3% walk rate. All of that was enough to make Vodnik one of the more impressive relievers in the Rockies’ bullpen last year, and after picking up nine saves in 2024 he figured to be in the conversation for the closer job once again this year.

That’s not how things have played out so far, as Vodnik has scuffled badly so far this season. While his 4.50 ERA isn’t markedly higher than last year’s figure, his peripherals have fallen off massively. Most notably, he’s walking an unacceptable 17.1% of his opponents while his groundball rate has dipped to just 42.9%. While these struggles have occurred in just nine appearances, Vodnik’s 6.52 FIP and 7.26 xERA are difficult to ignore. It seems as though Vodnik’s issues with finding the strike zone were at least enough to convince the Rockies to give him some time to reset on the injured list. If the issue is only a short-term issue and simply an opportunity for Vodnik to get sharp before returning to the big league bullpen, he could be back in the fold early next month. It’s possible a longer stay could be required as well depending on the severity of the injury, but no firm timetable for Vodnik’s ailment has been announced to this point.

Replacing Vodnik on the club’s roster is Agnos, a tenth-rounder from the Rockies’ 2022 draft. The 24-year-old hurler was primarily a hitter in college but converted to pitching upon being drafted. After a strong 2023 season where he mowed down hitters at Single-A Fresno to the tune of a 2.06 ERA with a 30.8% strikeout rate, Agnos followed that up with an even more dominant showing at the High-A and Double-A levels last year. He struck out 31.3% of opponents while showing off a 1.38 ERA, including a 1.95 ERA with the team’s Hartford affiliate. That was all more than enough to earn Agnos a call-up to Triple-A to start 2025, and so far he’s picked up right where he left off with a 2.25 ERA and 32.3% strikeout rate in eight innings of work. That exciting production will now get a chance in the majors, albeit with the challenge of calling Coors Field home attached as well.

Making room for Agnos on the 40-man roster is Justice. The southpaw did not appear in the majors this year but has had brief stints with Colorado in each of the past two campaigns. A fifth-rounder selected by the Rockies back in 2021, Justice has just 7 2/3 innings of work at the big league level during which he’s surrendered a 8.22 ERA and 5.08 FIP. The lefty has walked (9) more batters than he’s struck out (8) while also allowing 14 hits in ten appearances. The Rockies will have one week to try to work out a trade involving Justice or else attempt to pass him through waivers. Should he manage to get through waivers unclaimed, the Rockies would then have the opportunity to outright him to the minor leagues to serve as non-roster depth going forward.
