Mark Trumbo back in AL West -- with Mariners, not Angels

The Angels’ left fielders are batting .191 this season and have combined for four home runs. As a team, the Angels’ slugging percentage ranks 13th in the American League, the lowest in the American League West.

On Wednesday, the Angels passed on a chance to improve in both areas. Slugger Mark Trumbo, who played the first four seasons of his career with the Angels, was traded from the Arizona Diamondbacks to the Seattle Mariners.

The Angels did not engage in serious trade talks to bring back Trumbo. They would like to upgrade in left field, but they would prefer a left-handed hitter to balance Mike Trout and Albert Pujols in their lineup. If an impact right-handed bat becomes available, they would consider that too, but they thought it was too early to trade from their limited prospect base before seeing whether a better fit might be available at a later date.

Trumbo, 29, is batting .259 with nine home runs in 46 games. His .506 slugging percentage ranks sixth among National League outfielders, behind Bryce Harper of the Washington Nationals, Joc Pederson and Andre Ethier of the Dodgers, Justin Upton of the San Diego Padres and Giancarlo Stanton of the Miami Marlins.

The Angels traded Trumbo to Arizona after the 2013 season in a three-way deal that brought pitchers Hector Santiago and Tyler Skaggs to Anaheim.

The Diamondbacks on Wednesday traded Trumbo and pitcher Vidal Nuno to Seattle for pitcher Dominic Leone, catcher Welington Castillo and two prospects -- outfielder Gabby Guerrero, ranked seventh among Mariners prospects by Baseball America, and infielder Jack Reinheimer, ranked 17th.
