Trachsel will fall behind Jeremy Guthrie and in front of Daniel Cabrera, giving the Orioles three right-handers in a row.
"Our rotation for Tampa is Guthrie, Trachsel, Cabrera. I wanted to wait for Trachsel to throw a bullpen today," said Baltimore manager Dave Trembley before Wednesday's game against the Yankees. "It's going to be interesting to see him pitch, to see how his command is and how his control is. But hopefully he'll be all right. You know, he's pitched for a long time."
Trachsel, the elder statesman on Baltimore's staff, has struggled through his first seven starts. The right-hander has been knocked out before the end of the fourth inning three times, sinking the Orioles to some early deficits. The Orioles originally skipped him because of some off-days, and Trembley elected to keep the rest of the staff on turn.
"I'm trying to keep as many guys close to pitching on their regular turn as I possibly can," he said last week. "Until such a point where I can turn the rotation over and do that, I'm not going to mess with it. I think it's important for routine. ... With all due respect to Steve -- whom I have a great deal of respect for -- I'm not going to upset the apple cart for one guy."
