Bergesen can pitch out of the bullpen tonight if he's needed, and he's slated to start Sunday in Cleveland.
Bergesen was optioned to Norfolk over the weekend, but he never reported. He met the club in New York and waited to join the 25-man roster.
A postponement tonight most likely would have caused the Orioles to send Bergesen to the Tides because they wouldn't have needed him on Sunday.
In his only start, Bergesen allowed two earned runs (four total) in 3 2/3 innings last Wednesday against the Tigers.
The Hardy move is retroactive to Sunday. He's batting .200, and all three hits are doubles. He's also got two RBIs in six games.
Also, the Orioles still expect left-hander Brian Matusz to rejoin the team in Baltimore after the road trip concludes on Sunday. He threw off flat ground again today in Sarasota.
