Showalter didn’t disclose when O’Day was having the surgery or who was performing the procedure, but said that the recovery time is six months.
O’Day is the second key Orioles reliever to be lost for the season because of injury. Left-hander Richard Bleier had surgery to repair a lat muscle tear on his left side earlier this month.
O’Day might have been able to return late this season if he decided against having surgery — a 10- to 12-week timetable was placed on that recovery — but Showalter said surgery will likely completely resolve the injury heading into next season.
“It gives you a lot better chance of it not being an issue again,” Showalter said of O’Day’s decision to have surgery. “That’s important.”
O’Day received a second opinion from a specialist in Nashville on Friday before deciding whether to have the procedure.
With O’Day’s season over, the Orioles not only lose his on-field contributions, but also the opportunity to dangle him as a trade chip. O’Day, who was placed on the 60-day disabled list earlier this week, is in the third year of a four-year, $31 million deal.
He injured his hamstring while coming off the mound to field a ball in the Orioles’ 3-2 loss to Seattle on Tuesday. Last week, O’Day didn’t pitch over a four-game stretch because of his hamstring, but avoided the DL and returned to make four more appearances before injuring it again.
Showalter seeking results from Tillman
As right-hander Chris Tillman prepares to make his third minor league rehabilitation start Saturday night for Triple-A Norfolk, Showalter said he wants to start seeing better results from Tillman.
“This is about getting people out at the level the he should be getting people out if he’s coming back here,” Showalter said. “You’re kind of being nice that it’s a mixed bag, so I’d really like to see him have one or two quality starts down there and pitch like a guy who is better than that level. That’s what I’d like to see personally. I can’t speak for everybody else.”
After two starts, Tillman is yet to record a full four-inning outing while pitching at two low-level Orioles affiliates. He allowed three runs in the first inning in his first rehab outing, a two-inning stint with Short-A Aberdeen, and allowed two runs over 3 1/3 innings in his second start with Low-A Delmarva.
Around the horn
Orioles competitive balance pick Cadyn Grenier and third-rounder Blaine Knight will have their physical exams in the next few days, according to a team source. Grenier, a shortstop from Oregon State, and Knight, a right-hander from Arkansas, just finished their college seasons with their teams playing against each other in the College World Series, which was won by Oregon State. Both are expected to sign by Wednesday’s 5 p.m deadline. … In making his major league debut Friday night, reliever Ryan Meisinger became the 24th Maryland-born player to appear in a game with the Orioles. The Dunkirk native is the first since Baltimore natives Steve Clevenger and Steve Johnson played for the club in 2015. … The Orioles honored fallen Baltimore County officer Amy Caprio with a Birdland Heroes community award during Saturday’s game. Caprio’s husband, Tim Caprio, accepted the honor on her behalf. The 29-year old officer was killed in the line of duty May 21 in Perry Hall.
