The Opening Day roster for the Orioles isn’t going to include infielder Jorge Mateo. The fastest player in camp made a speedy exit from it.On the first workout day, executive vice president/general manager Mike Elias confirmed that Mateo is making progress but probably won’t get enough at-bats to be ready on March 27 in Toronto.

With camps opening for spring training, it’s common for clubs to provide updates on player health or the lack thereof. Orioles general manager Mike Elias

Heston Kjerstad arrived early at Orioles spring training, well ahead of the report date for position players. He’s fighting for a roster spot in a crowded outfield, and if he doesn’t make the club, it won’t be for lack of an opportunity.

There’s no indication that the injury will affect Mateo’s readiness for the start of next season. Baltimore was confident enough in his health to keep him around. He’ll join Ramón Urías and new backup catcher Gary Sánchez as locks for Brandon Hyde’s bench so long as he’s healthy.

MASN's Roch Kubatko reports that Baltimore Orioles infielder Jorge Mateo (elbow) will not be ready for Opening Day this year. Mateo had UCL reconstruction on his left (non-throwing) elbow last year and will not be ready in time when regular-season games kick off at the end of March.
