BOSTON -- It took until the 15th inning, but the Red Sox finally scored the winning run to defeat the Mariners 5-4 at Fenway Park. Stephen Drew's two-out, bases-loaded single kicked up chalk on the right-field line to score Dustin Pedroia with the winning run.
Lucas Luetge (0-2) took the loss, going 2 2/3 innings, giving up one run on two hits and four walks with a strikeout.
Drake Britton (1-0) earned the win, going two scoreless innings, giving up three hits with two strikeouts.
Boston's John Lackey started and went seven innings, giving up three runs on eight hits and a walk with six strikeouts. Seattle's Hisashi Iwakuma went 5 2/3 innings, giving up two runs -- neither earned -- earned, on seven hits and two walks with four strikeouts.
The Red Sox took a 4-3 lead in the bottom of the seventh on Pedroia's two-run homer off Seattle lefty Oliver Perez.
But, Seattle tied it in the top of the eighth on Kyle Seager's solo home run off Boston reliever Junichi Tazawa.
The Mariners had taken a 1-0 lead in the fourth inning when Brad Miller led off with a single off Lackey. Miller stole second base and scored on Seager's one-out double.
But the Red Sox went ahead in the fifth, thanks to two consecutive Mariners errors.
Brock Holt led off the inning with a double off Iwakuma. Jacoby Ellsbury reached when center fielder Dustin Ackley misplayed his fly ball and Holt raced to third. Holt scored on second baseman Nick Franklin's error. Pedroia's fielder's choice scored Ellsbury.
NOTES: Mariners' left fielder Raul Ibanez entered Wednesday's game batting .135, going 5-for-37, in 10 games since the All-Star break. He had not recorded an RBI in that stretch. ... Franklin's first-inning double in Tuesday's loss to the Red Sox was his 23rd extra-base hit in 53 games. The only other Mariners with more extra-base hits in the first 53 games of their careers were Alvin Davis with 27 in 1984 and Jose Cruz Jr. with 25 in 1997. ... 1B/OF Michael Morse, who was activated after a five-week stint on the disabled list with a strained right quad earlier this week, was back in the lineup for a second consecutive day batting sixth and playing first base. He has mostly played the outfield this season, but acting manager Robby Thompson said playing Morse at first base will give his legs a break. ... Right-hander Jake Peavy, whom the Red Sox acquired in a three-team trade Tuesday night was expected to arrive in Boston on Wednesday, but his arrival was delayed until Thursday. Manager John Farrell said Peavy will start one of the games on the team's homestand, which ends Sunday. ... Infielder Brock Holt was recalled from Triple-A Pawtucket on Wednesday, taking the roster spot of INF Jose Iglesias, who was traded to Detroit on Tuesday night. This is Holt's second stint with the Red Sox this season.
