The Orioles will recall right-handed reliever Preston Guilmet from Triple-A Norfolk on Monday to provide the club with some bullpen depth, according to an industry source.
The team optioned left-hander T.J. McFarland to Norfolk after he threw three relief innings in the Orioles' 5-2 loss to the Houston Astros on Sunday.
The Orioles will make the move official before Monday's series opener against the Detroit Tigers at Camden Yards.
Orioles manager Buck Showalter indicated after the loss that the team was planning to make a roster move to add a right-handed reliever for this week's three-game series against the Tigers, preferably one who could give the bullpen some length. Over the past several days, the Orioles have had four left-handers in the bullpen.
Guilmet, who was acquired from the Cleveland Indians last month in exchange for minor league infielder Torsten Boss, is 2-1 with a 5.65 ERA and four saves for Norfolk this season. But he's not a reliever who would appear to give the team a long-relief option. Just three of his 12 outings this season have been more than one inning.
Eight of his 12 outings have been scoreless -- he allowed one earned run in three others -- and other than giving up six runs in one-third of an inning Thursday, he has been pretty solid pitching for the Tides in the eighth and ninth innings.
Guilmet, 26, briefly pitched for the Indians last year, compiling a 10.13 ERA in 5 1/3 relief innings, allowing eight hits and six runs with one strikeout and three walks.
Fox Sports first reported that the Orioles were recalling Guilmet.
