Seeking to a bolster an inconsistent starting rotation to continue their playoff push, the Orioles acquired left-hander Joe Saunders and cash considerations from the D-backs on Sunday, in exchange for right-handed reliever Matt Lindstrom and a player to be named this winter. Baltimore gave Arizona right-handed reliever Matt Lindstrom and cash considerations or a player to be named later. Jake Arrieta, who was sent to Triple-A Norfolk in early July, arrived on Sunday afternoon to take Lindstrom's active roster spot. Eager to bolster an inexperienced pitching staff during their first playoff run since 1997, the Baltimore Orioles obtained left-hander Joe Saunders on Sunday in a trade with the Arizona Diamondbacks. "I like our ballclub's chances," said Dan Duquette, the Orioles vice president of baseball operations. Baltimore began the day tied for the second American League wild-card spot with Oakland and in third place in the AL East, only four games behind the division-leading New York Yankees.
