Mariners vs Red Sox Live Stream: Start Time, TV Channel & Key Matchups Tonight

BOSTON—The Boston Red Sox edged the Seattle Mariners 3-2 on Monday night at Fenway Park, riding early power and a strong outing from rookie left-hander Payton Tolle to tighten their grip on the American League Wild Card race. Red Sox catcher Nick Gasper opened the scoring in the bottom of the first with a 387-foot solo shot to right-center, his 14th homer of the season. One inning later, Jarren Duran drilled a two-run blast that plated Eric Sogard and gave Boston a 3-1 cushion the club would never relinquish. Seattle’s offense came from Randy Arozarena, who doubled home a run in the first and cut the deficit with a 402-foot solo homer in the third. But George Kirby (9-11) couldn’t match Tolle’s efficiency, allowing three runs on four hits over four frames before manager Dan Wilson turned to the bullpen. Tolle (9-6) scattered four hits, struck out six and walked none in six strong innings, lowering his ERA to 3.01. Setup man Greg Wisdom escaped a seventh-inning jam, and closer Kenley Jansen nailed down his 28th save with a perfect ninth, fanning Julio Rodríguez on a 99-mph fastball to end it. Key numbers • Boston improved to 74-63 and sits 8½ games behind the Yankees in the AL East but holds the third Wild Card spot by 1½ games. • Seattle dropped its fourth straight, falling to 64-74 and five games back in the AL West. • The Red Sox are now 3-1 against the Mariners this season and can clinch the season series Tuesday night. Notable moments • Defensive gem: Boston third baseman Rafael Devers ranged deep into foul ground to snag Cal Raleigh’s popup with two on and two out in the seventh, preserving the one-run lead. • Streak watch: Rodríguez’s RBI double extended his on-base streak to 23 games, the longest active run in the majors. What’s next Game 2 of the six-game set is Tuesday at 6:45 p.m. ET. Boston sends right-hander Shane Baz (6-3, 3.48) to the mound against Seattle southpaw Robbie Ray (4-7, 4.59).
