TORONTO – Roberto Osuna opted for caution after feeling what he called a "stretch" in the front of his shoulder and the Toronto Blue Jays closer expects to be ready later this week for the American League Division Series.

His exit during the 10th inning of Tuesday’s thrilling 5-2, 11-inning wild-card win over the Baltimore Orioles offered a moment of pause for his team, although both he and manager John Gibbons said the initial diagnosis suggests the injury isn’t serious.

"I threw the 2-1 pitch to (Chris) Davis, a fastball away, I felt a bit of a stretch in my shoulder, in the front part, and I went with the fastball up and in and I felt it a little bit (more), and I was like I’ve got to be out," Osuna said amid the champagne celebrations. "I don’t want to miss the next series, so that’s why I told Gibby take me out and I’ll be fine for Friday."

After Davis flew out to right field, Edwin Encarnacion came over to visit Osuna and waved to the dugout for Gibbons and trainer George Poulis to come out. He was later examined by one of the team’s doctors and was in the training room when Encarnacion hit his game-winning home run.

"The doctor told me I’m fine," said Osuna. "I just need a couple days off, but I’ll be good by Friday. He said, ‘It’s nothing big, you’re going to be fine in a couple of days.’ Hopefully I’ll be good for Friday."

Like many Blue Jays relievers, Osuna has worked often of late, but there’s been no public indication that he’s dealing with anything more than regular wear and tear. He was in his second inning of work Tuesday, retiring all four batters he faced.

"It wasn’t a big deal," Gibbons said. “It just tightened up on him. The smart thing to do was just get him out of there."

The 21-year-old appeared in 72 regular season games this year, posting a 2.68 ERA with 82 strikeouts in 74 innings while saving 36 games.
