Injury bug bites Orioles again as another starting pitcher lands on IL

The Orioles announced that they have recalled right-hander Dillon Tate and left-hander Nick Vespi. In corresponding moves, right-hander Jonathan Heasley has been optioned to Triple-A Norfolk, while righty Dean Kremer has been placed on the 15-day injured list due to a right triceps strain. Kremer’s IL move is retroactive to May 21.

The Orioles have not yet provided any information about the severity of Kremer’s injury, but it will provide the Orioles with a challenge nonetheless. Just a week ago, the club began a stretch of playing 42 games in 44 days and was planning to go to a six-man rotation to keep their starters fresh. However, John Means landed on the injured list Thursday due to a forearm strain, and now Kremer is on the shelf as well.

That leaves Baltimore with a rotation of Corbin Burnes, Kyle Bradish and Grayson Rodriguez. The latter two were also on the IL earlier this year, but each was reinstated this month. Cole Irvin and Albert Suárez were each in the rotation earlier this year but had been bumped to the bullpen. With the injury bug biting this week, both of them may have to return to starting roles.

That plan will come with a couple of challenges. Irvin threw 56 pitches in a relief outing on Wednesday and may not be available for a few more days. Suárez was stretched out earlier this year, but it’s been about two weeks since he pitched more than an inning.

Even if the O’s can find a way to smoothly transition Irvin and Suárez back to the rotation, that still leaves them with just five starters when they had planned on having six. Perhaps they consider that acceptable, but with Bradish and Rodriguez having already missed time this year, getting them a bit of extra rest during this tough part of the schedule could still be a priority.

Bruce Zimmermann is on the 40-man roster but has been on the minor league IL for almost two weeks now due to a hamstring strain. Cade Povich and Chayce McDermott, two of the club’s top pitching prospects, are pitching well in Triple-A, but neither is on the 40-man roster.

Whatever the Orioles are planning, more information may be forthcoming this weekend. Burnes is taking the ball Friday night, but Kremer was scheduled for Saturday. Both Bradish and Rodriguez pitched too recently to take the ball on normal rest by Saturday.
