Vodnik experienced shoulder soreness while warming up to enter Tuesday's game against the Nationals, MLB.com reports.
Vodnik was preparing to enter the game in the ninth inning with the Rockies leading 3-1 but could not pitch. After the game, manager Bud Black termed the decision as cautious and referenced Vodnik's recent workload. Angel Chivilli entered the game and earned his first career save, though Tyler Kinley had already pitched the eighth inning and would likely be the top choice for save chances if Vodnik is forced to miss additional time.
