MIAMI -- Milwaukee Brewers right-hander Joe Ross was placed on the 15-day injured list on Tuesday because of a low back strain.
Ross lasted just one inning in the NL Central-leading Brewers' series-opening game against the Miami Marlins on Monday night. The Brewers ended up using seven relievers and lost 3-2 in 10 innings.
"Definitely frustrating - I felt I was throwing well," Ross said Tuesday. "Frustrating because I want to go out there and pitch when my name is called."
The 31-year-old Ross is in his first year with the Brewers after five seasons with the Washington Nationals, where he alternated between starting and relief roles. Ross has been a fixture in the Brewers' rotation the first seven weeks of the season, going 2-4 with a 4.50 ERA.
"It doesn't seem like it's serious. Seems like it's nagging," Brewers manager Pat Murphy said before Tuesday night's 7-5 win over Miami. "You get it under control and he'll be back."
Milwaukee recalled right-hander Tobias Myers from Triple-A Nashville to fill Ross' spot on the roster.
