The Orioles haven't announced any roster moves, but Ryan Flaherty and Brian Matusz are at the ballpark.
Flaherty's equipment bag is at his locker and Matusz has actually been seen here.
It's possible that Matusz will replace J.C. Romero on the 25-man roster and Flaherty could become the fourth bench player with pitcher Tommy Hunter optioned to Triple-A Norfolk.
Update: Flaherty has now been seen in the clubhouse for a touching reunion with his equipment bag. Plus he's in the lineup.
Hunter is no longer listed among the team's starters, indicating he's likely one to go.
As for tonight's series opener against Toronto, here's the Orioles batting order:
Nick Markakis RF
J.J. Hardy SS
Nate McLouth LF
Adam Jones CF
Matt Wieters C
Chris Davis DH
Mark Reynolds 1B
Ryan Flaherty 2B
Manny Machado 3B
Zach Britton LHP
