Kyle Seager hit a grand slam in the eighth inning and a game-winning home run in the 10th on Tuesday night to lift the Seattle Mariners to a 7-6 victory over the Tampa Bay Rays.

The game-winner, Seager's 10th home run of the season, came off Brad Boxberger (2-2) after the Rays had rallied for three runs to tie the game in the ninth.

Seager's eighth-inning slam off Jake McGee had given the Mariners a 6-3 lead. Seager drove in six runs with three hits and extended his hitting streak to 12 games.

Evan Longoria's bases-loaded double off the top of the wall, his third hit of the game, drove in two of the ninth-inning runs.

The Rays' fourth straight loss dropped them a half-game behind the New York Yankees in the AL East.

Fernando Rodney (2-2) got the win after giving up the three runs in the ninth. Joe Beimel pitched the 10th for his first save.

McGee gave up the grand slam on the first pitch after second baseman Nick Franklin's error on a potential double-play ball.

Jake Elmore drove in four runs for Tampa Bay.

Rays starter Alex Colome gave up two runs and four hits in a 38-pitch first inning in which he contributed one of the Rays' three defensive misplays.

Austin Jackson, Seth Smith and Cano opened the game with singles, marking the third straight game the Rays have fallen behind before getting an out. Seager followed with a one-out bouncer which Colome fielded, but threw low to the plate, allowing Smith to score. The play was scored a single, Seattle's fourth hit of the inning.

Elmore tied it with a bases-loaded, two-out single in the first off J.A. Happ.

The first inning took 45 minutes, including a 2-minute, 57-second review of the play at the plate.

Happ, who is 3-0 in his last seven starts, pitched six innings, giving up seven hits and three runs.

Colome gave up two runs and five hits, leaving the game in the sixth with a 3-2 lead.
