"Randy pitched well here last year," manager Buck Showalter said, referring to a seven-inning outing at Fenway Park in which Wolf allowed two runs, "and he feels good, and I think we can cover. You also got to think about where it puts your bullpen, too."
With expanded rosters and an off-day Thursday, the Orioles feel OK removing Wolf from the 'pen to make another start. Wolf is 2-1 with a 2.73 ERA in four career starts at Fenway, and he also pitched last Saturday's game in Oakland after working out of the bullpen upon initially signing with Baltimore.
Showalter said the other two candidates to pitch Saturday -- lefty Zach Britton and right-hander Jake Arrieta -- will be available out of the bullpen. The duo, along with Steve Johnson, are options to start one of Monday's doubleheader games vs. the Blue Jays, with Wei-Yin Chen starting the other game.
