Mariners acquire outfielder Taylor Ward in trade with Orioles

The Mariners have addressed their biggest roster need on trade-deadline day, acquiring outfielder Taylor Ward from the Baltimore Orioles in a four-player trade Monday, industry sources with knowledge of the deal told The Times.

In another strong signal of their intention to push for a playoff berth, the Mariners do not plan to trade free-agent-to-be Randy Arozarena, sources told The Times.

The Mariners do remain engaged on potentially trading another starting pitcher — likely either George Kirby or Emerson Hancock — before Monday’s 3 p.m. deadline.

Seattle is sending reliever Alex Hoppe and two minor-league pitchers — Brock Moore and Harrison Kreiling — to Baltimore in the Ward deal, a source said.

Ward, 32, will be a free agent at the end of the season.

All season, Seattle has ranked as one of the worst offenses in the majors against left-handed pitching, and acquiring a right-handed bat like Ward was a priority leading up to Monday’s deadline.

Ward is a familiar figure in the AL West, having spent his first eight years with the Los Angeles Angels. He was traded to Baltimore last winter for starting pitcher Grayson Rodriguez.

In 2015, Ward was the Angels’ first-round pick when Mariners president Jerry Dipoto was still the Angels’ general manager.

Ward hit .246 with seven homers, 20 doubles and a .730 OPS in 506 plate appearances with the Orioles this season.

His power numbers are down this season — his .346 slugging would be a career low in a full season — but his .383 on-base percentage is a career high.

Ward’s 87 walks this season lead the American League.

Ward should be especially useful against left-handed pitching. He has a .269/.413/.426 slash line (.839 OPS) in 138 plate appearances against lefties this season, compared to a .238/.372/.318 slash line (.690 OPS) against righties.

Ward has been the Orioles’ primary left fielder, but he could be an option to play right field or DH with the Mariners.

The Mariners are hopeful Ward will arrive in Seattle in time for the start of Tuesday’s series against the Tigers.

Brendan Donovan, the Mariners’ opening-day third baseman, is also expected to be activated from the injured list on Tuesday, putting the Mariners’ lineup at full strength for the first time since early April.
