Scott has been battling the injury for most of the season and needed to be placed on the 15-day disabled list earlier this month as the ailment continued to act up. He made a brief attempt at a comeback, going 5-for-10 in three rehab games with Double-A Bowie last week, and 0-for-3 in his return to the Orioles on Friday.
But after Friday's game Scott continued to experience pain in his shoulder, and the team decided to place him back on the disabled list. Tuesday's surgery guarantees that he will stay there for the rest of the season.
"Luke was upbeat," Orioles manager Buck Showalter said. "Hopefully they can get it taken care of. Dr. Andrews was pretty matter-of-fact about what he thought the next step should be. It's really the second group to kind of concur with the same thing that our doctors felt. So I think they've got their arms around it and I'm hoping that Luke is on his way to a healthy recovery."
The Orioles' outfielder finishes his season batting .220 (46-for-209) with nine home runs and 22 RBIs in 64 games. It's the first time since 2005 that Scott has played less than 65 games in a season and snaps his three-year streak of at least 20 home runs and 65 RBIs.
With Scott shelved for the remainder of the season, there are plenty of at-bats to go around for some of the Orioles' younger players. That includes 27-year-old Nolan Reimold, who has seen the majority of time in left field during Scott's absence.
Reimold is batting .239 (22-for-92) with five home runs and 26 RBIs in 34 games so far this season. But he may not be the only one to benefit from Scott's absence.
"We'll see what the situation dictates," Showalter said. "We have other people on this club that also deserve to play. But we've given Nolan a good share of at-bats lately and we will continue to try to create ways to keep everybody involved."
