"If the shot helps, then hopefully the thing will be behind us and I can get back to doing everyday stuff," Pearce said. "I'm optimistic. I'm not worried that this is a long-term thing, especially because I've had good results with the cortisone shot in the past."
Pearce said the elbow has been bothering him for a couple of months.
"But it's been under control," he said. "I think it just flared up by going back in the outfield and throwing the baseball. Right now we're trying to get it calmed down and get back on the field."
Orioles manager Buck Showalter thinks Pearce could be ready to go for the series against the Giants that opens Friday in San Francisco.
Left-hander T.J. McFarland had his bullpen session in Florida rained out. He'll try it again Wednesday.
