The Orioles played things close to the vest on Monday, when they declined to officially explain the presence of two southpaw pitchers. Brian Matusz, who is expected to make his big-league debut on Tuesday, worked out at Comerica Park on Monday.
Baltimore also got a guest-starring appearance from Chris Waters, who worked out with the team before the clubhouse was opened to the media. Waters may or may not join the team as a reliever on Tuesday, and he could also be a candidate to start on Friday.
“I think it depends on what happens tonight,” said manager Dave Trembley. “We need to see what our needs are after tonight’s game. Is that honest and up front?”
Trembley has said that starter Jason Berken’s role is being re-evaluated, and the youngster could be used in relief over the next couple days. In that case, Waters would likely take his slot on Friday, which would necessitate another roster move by the Orioles.
