Wily Mo Pena clubbed a two-run home run and 2, in the last of a game series.
Pena finished 3-for-3 and scored twice, all part of a 16-hit onslaught. Kyle Seager doubled three times and posted four total hits with three runs scored and an RBI. Brendan Ryan also had a two-run triple for the Mariners, who won three of four in the series.
That was more than enough for Felix Hernandez (12-11), who gave up two runs on seven hits with 10 strikeouts and two walks over six frames.
Shelley Duncan, a fill-in for Shin Soo-Choo, finished with three hits and an RBI for the Indians, who have dropped six of seven overall. Choo was a late scratch after injuring his left side during indoor batting practice prior to the game.
Josh Tomlin (12-7) was hit around to the tune of six runs on 11 hits with six strikeouts and one walk over 4 2/3 frames. Tomlin had gone at least five frames in first 37 career starts, one of only two pitchers to do so since 1919. He shares the record with former Indians pitcher and current Toronto manager John Farrell.
