Mariners 10, Red Sox 8 (12 innings)
BOSTON -- Catcher Mike Zunino delivered the go-ahead RBI-single to left in the 12th inning and third baseman Kyle Seager tacked on another one as the Seattle Mariners avoided a three-game sweep with a 10-8 win over the Boston Red Sox in Sunday's series finale at Fenway Park.
Zunino took advantage of a bases-loaded situation with nobody out, lacing a ball over the shortstop's head to plate center fielder Austin Jackson, who led off the 12th with a single.
Designated hitter Mark Trumbo's single moved Jackson to second and a sacrifice bunt from first baseman Logan Morrison resulted in a fielding error to load the bases.
Seager was 0-for-26 with runners in scoring position before his 12th-inning single plated pinch-runner Brad Miller.
Seattle (54-64) had been outscored 37-11 in the first two games of the series.
Mariners left fielder Franklin Gutierrez blasted two home runs in the first three innings -- including a three-run bomb in the third -- and drove in four runs.
Gutierrez's first long ball came right after second baseman Robinson Cano's first-inning, two-run homer as the Mariners scored three runs in the first, four in the third, and one in the seventh.
Cano had five hits and three RBIs and right fielder Nelson Cruz hit a solo shot in the seventh for his MLB-leading 36th home run, extending his career-high on-base streak to 27 games.
Vidal Nuno couldn't snap his winless streak, as the Mariners' southpaw failed to record a victory for a major league-worst 18th straight start.
Nuno lasted 4 1/3 innings, giving up four runs on nine hits and a walk.
Seattle left-hander Rob Rasmussen (2-1) earned the win in relief and right-hander Danny Farquhar shut the door for his first save of the season.
Henry Owens was up and down in his Fenway debut, as the rookie Red Sox left-hander surrendered seven runs on 10 hits and one walk while striking out 10 in six innings.
Left-hander Craig Breslow (0-3) took the loss for Boston (52-65)
Red Sox shortstop Xander Bogaerts and right fielder Rusney Castillo each hit solo home runs over the Green Monster in the third and fourth, respectively.
After a pair of sacrifice flies in the fourth and fifth, Boston pulled within two on Bogaerts' RBI-groundout in the seventh and a wild pitch that allowed third baseman Brock Holt to score.
Bogaerts delivered another RBI-groundout with runners on the corners and one away in the ninth to make it 8-7.
After loading the bases with two outs in the ninth, Red Sox third baseman Travis Shaw tied the game with a bloop single to left.
Designated hitter David Ortiz, who reached on an intentional walk and advanced to second on Castillo's infield single, tried to score but was thrown out at the plate to force extras.
