The Rockies reinstated Vodnik (biceps) from the 15-day injured list Sunday.
Vodnik made his lone rehab appearance with Double-A Hartford on Friday, when he struck out two batters over one inning. He will rejoin the Colorado bullpen for Sunday's series finale against the Brewers, though it's unclear if Vodnik will immediately reclaim the closer's role or if he'll instead get eased into higher-leverage situations. Across 55 major-league appearances this season, Vodnik has recorded nine saves and six holds with a 4.04 ERA and 1.48 WHIP across 64.2 innings.
