Showalter said he didn't expect the Orioles to make another move before rosters expand Sept. 1, "but that doesn't mean Dan [Duquette] doesn't have something up his sleeve." Duquette, the club's executive vice president, has been looking to add a bat, preferably right-handed, this month. … Infialder Ryan Flaherty, who was sent to Low-A Delmarva on Tuesday, was scheduled to be the Shorebirds' DH on Wednesday because of field conditions. He is expected to play Thursday for the Shorebirds and then Saturday through Monday at High-A Frederick before re-joining the Orioles. … After losing 13-2 on Tuesday, the Orioles have now allowed 13 or more runs to the Red Sox 23 times in the clubs' histories, including 15 times at Fenway Park. It was the 10th time the Orioles allowed 13 or more to Boston since the 2002 season. … Infielder Travis Adair, who had an 18-game hitting streak at High-A Frederick, was promoted to Double-A Bowie on Wednesday. He is the son of Rick Adair, who was the Orioles pitching coach before taking a leave of absence earlier this month.
