Adams has been dealing with the injury all season, although he initially thought it was a groin issue and was treating it as such while with Triple-A Norfolk. It was so painful at one point that Adams couldn't lift his leg out of bed one day, and an MRI about two weeks ago revealed a tear in the area and confirmed it was a sports hernia.
"It's just not getting any better and I talked to [manager Buck Showalter], and it was just one of those things, 'Why wait another week? Why not just get it done now?'" Adams said of the procedure, which has a relatively quick recovery period and would have him ready for Spring Training.
The official date hasn't been scheduled, as the Orioles await a medical callback, although Adams acknowledged it would probably be within the next week and that it's likely he goes to Philadelphia to see a specialist. After struggling in his first callup earlier this season, the 24-year-old has made strides in his second stint with the big league club, hitting safely in 14 of 19 games and posting a .303 batting average over that stretch.
"We've seen some things that he has done better up here than he was doing when he originally got here," Showalter said of Adams, who has worked hard to try to shore up his defense and adjust to the faster tempo of the Major Leagues.
"I don't think anybody can say for sure what they've seen from him -- with the health factor, how much that has affected him. I think running, moving around, first step, so I think I'm still very open-minded about where he might fit in our plans as we go forward. I think there is some unknown until you see him completely healthy."
Adams said the injury has made him slower to the ball in the middle infield, and given that he's experienced a lot of groin discomfort, it makes it difficult to fully swing and incorporate his lower body. Still, the young second baseman said he wasn't overly disappointed with his season or not being able to show the Orioles what he can do when he's 100 percent.
"I got to be here, so I just look at it as being fortunate enough to get up here," Adams said. "And I just look forward to getting better and getting it healthy for next year."
