SEATTLE -- The Orioles placed second baseman Brian Roberts on the 15-day disabled list before the start of Tuesday's game, as the 34-year-old was diagnosed with a right groin strain after an MRI was taken in Seattle earlier in the day.
Roberts first alerted manager Buck Showalter to some groin soreness on Monday afternoon and he was not in the lineup for Monday's series opener against the Mariners. He came to Safeco Field on Tuesday afternoon with worsened symptoms and was able to immediately get tests taken to further diagnose the injury.
"I know they set it all up very quickly and went to take a look at that, because he had some hip issues ... that he didn't mention yesterday," Showalter said.
Showalter said it's his understanding that the injury was not related to Roberts' concussion history, although the DL situation did afford the Orioles the opportunity to recall outfielder Xavier Avery within the 10-day window. Avery was optioned to Triple-A Norfolk after Saturday's game and was in Seattle on Tuesday afternoon while the team awaited the results of Roberts' MRI.
This is the second trip to the DL for Roberts this season, and is an all-too-familiar scenario for the Orioles, who have had their leadoff hitter -- and longest tenured current player -- for just 115 games over the past three seasons.
Roberts made his season debut on June 12 after being activated off the 60-day DL, a triumphant return in which he went 3-for-4 with an RBI in his first Major League game since May 16, 2011. But he struggled to keep up that momentum, hitting the DL with a .182 batting average, five RBIs and two runs scored in 17 games.
"We've basically had two people on the bench [Monday] night, one of them as a catcher," Showalter said. "And it really affects how you manage a game, position- and pitching-wise. Also, you got to keep in mind with four days off for the All-Star [break], that kind of lends toward it."
Roberts joins a long list of currently injured O's including Nick Markakis, Nolan Reimold -- who is likely out for the season -- Endy Chavez, Taylor Teagarden, Nick Johnson and Stu Pomeranz. Roberts is expected to report to the team's spring complex in Sarasota, Fla., to start rehabbing, with Robert Andino taking over every day second-base duties.
