Trachsel is expected to join Jeremy Guthrie, Adam Loewen, Daniel Cabrera and either Brian Burres or Matt Albers on Baltimore's starting staff, and he'll start the season with more career wins (141) and losses (154) than the rest of the starters combined. Last year, Trachsel allowed three earned runs or less 17 times for the Orioles.
Baltimore also optioned Jim Johnson to Triple-A Norfolk and announced that Jon Leicester has accepted an assignment to Norfolk. Leicester had been outrighted off the 40-man roster earlier in the week.
