Seager, a third-year pro out of Charlotte, NC, socked a home run, two doubles and a single in five at-bats, drove in three runs and scored three times, but Seattle pitchers could not take advantage of his effort, giving up 17 hits to the relentless Angels, who evened their home record at 20 wins and 20 losses.
Having a solid season as the regular third baseman, Seager has nine homers and 33 RBI to go with a .287 batting average.
The loss dropped the Mariners 10 1/2 back of the A's, who lead the AL West by a game over the Rangers. The Angels are nine out, with hopes of catching the two front-runners as the season wears on.
Tying Cardinal hurlers Lance Lynn and Adam Wainright for the league lead with his 10th win, Zimmermann blanked the Rockies - losers of four straight - through seven innings, giving up an unearned run in the eighth. Rafael Soriano pitched a perfect ninth in relief.
Zimmermann gave up six hits, fanned nine and allowed just one walk. The Washington hurler lowered his ERA to 2.26, fifth-best in the NL. He's stuck out 76 and walked just 15 batters in 107 2/3 innings, a K-BB ratio of better than 5-1.
