Mariners deal lefty Wade Miley to O's for LHP prospect Ariel Miranda

The Baltimore Orioles acquired Wade Miley from the Seattle Mariners on Sunday, giving manager Buck Showalter a veteran left-hander for his rotation as the team tries to hold off Toronto and Boston for the division title.

"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."

Miley, who was acquired by the Mariners in an offseason trade with the Red Sox, has struggled this year with a 7-8 record and 4.98 ERA, but he had a 3.45 ERA in five July starts. He pitched seven innings of one-hit ball and struck out nine in Seattle's 4-1 victory against the major league-leading Chicago Cubs on Saturday.

"He was probably as good as he has been all year,'' Seattle manager Scott Servais said after Saturday's win at Wrigley Field. "He kind of brought a different attitude, mentality, whatever you want to say, to the mound today. He was very aggressive from the get-go."

Miley was shagging fly balls before Sunday's game against Chicago when he left the field while Seattle continued taking batting practice. Servais soon followed him into the dugout.

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. He appeared in one game for Baltimore on July 3 at Seattle, allowing three runs and four hits in two innings while striking out four.

"Ariel Miranda is a power, left-handed pitcher with a four-pitch mix that is major league-ready that provides us with flexibility," Mariners general manager Jerry Dipoto said in an email to the Associated Press. "We are very excited for what he can bring to the Mariners."

The 29-year-old Miley was selected by Arizona with the 43rd pick in the 2008 amateur draft and made his major league debut with the Diamondbacks in 2011. He set Diamondbacks rookie records for wins (16), starts (29) and innings pitched (194.2 IP) in 2012 en route to his only All-Star Game appearance.

Miley is 56-54 with a 4.07 ERA in six years in the majors and has started at least 32 games in each of the past four seasons.

He went 11-11 with a 4.46 ERA in 32 starts with Boston last year and then was traded to Seattle in December.

"We are glad that Wade can go from one team in playoff contention to another, and to a division that he has had success in during his career," Dipoto said. "This decision is the best move for the Mariners' present and future."

Miley is making $6 million this season and is owed $8.75 million in 2017. His contract includes a $12 million club option for 2018 with a $500,000 buyout.
