Orioles notes: Despite positive news on knee, Mark Trumbo likely heading to disabled list

Mark Trumbo received some good news Friday when an MRI revealed no structural damage in his right knee, but the Orioles were still preparing to place the slugger on the 10-day disabled list. However, the Orioles didn’t make the move Friday as it opened a series at the Tampa Bay Rays.

Trumbo said the MRI did reveal some “fairly advanced” arthritis and some chondromalacia (cartilage damage under the kneecap) that he will likely have to play through for the rest of his career. He aggravated the injury while sliding into second base during Tuesday’s game at the Chicago White Sox.


While the Orioles' Chris Tillman is working his way back from an unusual back injury, he's also trying to find his way back to his old form.

“It kind of shows some pretty decent wear and tear, but the good news is all the ligaments and everything are intact,” Trumbo said. “So there are some positives, but at the same time, we know what is causing the pain. … There will be pain associated for the rest of my playing days at least, but that’s something I’ve had from years of wear and tear, and I think the slide kind of jarred something that caused some inflammation. But the good news is the meniscus and everything looks good. I think that’s the most positive news in that regard.”

Trumbo was scheduled to have his knee drained Friday and received a cortisone injection, manager Buck Showalter said, which would sideline him from all activities for at least three days and likely force him to be out for about a week.


With that timetable, Trumbo – who last played Tuesday – a DL stint makes sense. He would be eligible to return on June 2.

“We found out what we were hoping,” Showalter said of the MRI results. “So it’s kind of good. I think it relieves any of his anxiety that he might have that structurally it’s in good shape. ... I think we’re leaning toward a DL for Mark after the game. Kind of wait and see if we’re going to need a pitcher or position player here.”

Trumbo, 32, had been hitting well since returning from a quad injury that forced him to open the season on the DL. Since returning May 1, he was hitting .309/.317/.469 in 20 games and had a four-hit game Tuesday even though he did make a costly late-inning error in right field.

Trumbo said he’s played through knee pain over his career.

“It’s not the end of the world,” Trumbo said. “It can be annoying. Some days can be worse than others. But some of that stuff, once it’s gone its gone. I guess that’s the tradeoff of doing what we do. Some of that stuff is going to take its toll and that’s what’s going on.”

Simulated game for Britton

Orioles closer Zach Britton is scheduled for a two-inning simulated game before Saturday’s late-afternoon start at the Rays.

Britton will continue to ramp up the intensity of the simulation of his outings. The Orioles are summoning two hitters and four infielders from extended spring training in Sarasota to help.

Ynoa update

Right-hander Gabriel Ynoa is beginning to throw long toss after receiving a cortisone injection in his shoulder and said Thursday that he’s scheduled to begin throwing bullpen sessions Monday.

Ynoa opened the season with season on the DL with a shin injury, but then after a week of playing catch, he began to feel discomfort in his shoulder.

Ynoa estimated he’s still about a month away from being able to return.

O’Day update

Right-hander Darren O’Day was still scheduled for a cortisone injection Friday, which should accelerate his slow recovery from a hyperextended right elbow, but will also shut him down from all baseball activities for at least three days to allow the injection to take effect.
