BALTIMORE — Orioles right-hander Brad Bergesen will be slowed at the start of spring training after hurting his shoulder while filming a promotional spot in December, an injury that caused the team to instituted a new policy regarding commercial shoots.

Bergesen strained his right shoulder while performing in a commercial promoting Baltimore’s 2010 season. He will see limited action for a week to 10 days after the Orioles pitchers and catchers begin workouts Thursday in Sarasota, Fla.
Bergesen had his rookie season cut short last year after being hit in the shin by a line drive on July 30. The right-hander had not thrown off a mound from August until the commercial shoot, and he hurt himself by throwing at game-speed.
“He just did too much, too soon,” said Andy MacPhail, the club president of baseball operations, said Tuesday from Sarasota. “He’s behind the rest of the pitchers at this point, but it’s nothing we think is going to delay his regular season.”
MacPhail said the club will monitor the filming of commercials in the future.
“We will make sure we have one of our medical personnel or baseball operations personnel present from now moving forward,” he said.
Bergesen was 7-5 with a 3.43 ERA in 19 starts last season. He is expected to be part of a rotation that includes Kevin Millwood, Jeremy Guthrie, Brian Matusz and Chris Tillman.
