The Baltimore Orioles acquired Wade Miley from the Seattle Mariners on Sunday, giving manager Buck Showalter a veteran left-hander for his rotation.

"Wade Miley is a workhorse, veteran left-handed starter who likes to pitch and compete," said Dan Duquette, the executive vice president of baseball operations for the Orioles. "We think he will contribute to this year's club with some quality innings."

Seattle received left-handed prospect Ariel Miranda, 27, in the trade. The Cuban pitcher has spent most of the year with Triple-A Norfolk and was 4-7 with a 3.93 ERA in 19 starts.
