Manager Dave Trembley said it would have been "too much" to ask Simon to pitch on back-to-back days. A starter who was moved to the bullpen barely two weeks ago, Simon is less than a year removed from Tommy John surgery on his right elbow.
"I think you would have been asking for problems," Trembley said. "I don't think it would have been the right thing to do."
When asked if Simon's situation was similar to that of former Orioles reliever Danys Baez, who missed all of 2008 after undergoing surgery on his right elbow and was handled with caution last season, Trembley said no.
"I don't think it'll be like it was with Danys," Trembley said. "But once again, if [Simon] goes out and has a six-out inning instead of three and throws 37 pitches instead of 20 ... Each game you've got to take it one game at a time."
