BOSTON — Giancarlo Stanton called the Yankees’ win over the Red Sox on Friday night “a great first punch to the series.”
Stanton delivered the second blow Saturday, with a mammoth go-ahead grand slam in the eighth inning that sent the Yankees to a 5-3 victory at Fenway Park.
The win was the Yankees’ fifth straight and moved them into a tie with Boston for the top AL wild-card spot.
The Yankees trailed 2-0 through five after the offense sputtered for much of the game against right-hander Nick Pivetta. But the Yankees scratched out a run in the sixth before Stanton turned the game around in the eighth.
After Boston right-hander Tanner Houck pitched around a pair of leadoff walks in the seventh and didn’t allow a run, he struck out Rougned Odor and Gio Urshela to start the eighth.
Brett Gardner walked and stole second with Aaron Judge at the plate.
Judge walked and Houck — who walked four in just 1²/₃ innings — was replaced by left-hander Darwinson Hernandez to face the lefty-swinging Anthony Rizzo, whom the Yankees stuck with rather than going to righty-hitting Luke Voit.
Hernandez hit Rizzo with a 3-1 pitch to load the bases for Stanton.
Stanton responded with a towering homer over the Green Monster in left that measured at an estimated 452 feet, silencing much of the sold out crowd of 36,103.
Luis Severino, in his second appearance out of the bullpen since his return from Tommy John surgery, pitched two scoreless innings, the seventh and eighth.
In the ninth, Aroldis Chapman gave up a one-out solo homer to Dalbec to cut the Yankees’ lead to two. Chapman then drilled Kevin Plawecki with a pitch and struck out Jose Iglesias before Kiké Hernandez grounded out to third to end it.
Yankees starter Nestor Cortes Jr. retired the first seven batters he faced before former Met Kevin Plawecki blasted a home run off the light tower above the Green Monster in left to give the Red Sox a 1-0 lead in the third.
The Yankees got just a leadoff single from Stanton in the second off Pivetta, who retired 13 in a row after Stanton’s hit before an Urshela liner just got by Xander Bogaerts at shortstop and into left field with one out in the sixth.
Pivetta had a 7.32 ERA in his previous five starts, but allowed just one run in 5¹/₃ innings Saturday.
Odor, in his first plate appearance in nearly two weeks and first start since Sept. 8, hit a fly ball to deep right that was caught by Hunter Renfroe before it reached the seats in the second.
Judge made an even better play on a Dalbec shot to prevent at least an extra-base hit — and perhaps a two-run homer — with a terrific running catch in the fifth.
Plawecki followed Dalbec with a single to center to end Cortes’ outing after just 4 ¹/₃ innings. Michael King came on to face Jose Iglesias and gave up a dribbler to third that went for an infield hit to load the bases.
With Hernandez at the plate, King’s wild pitch scored Kyle Schwarber from third to make it 2-0, Red Sox.
It also forced the Yankees to bring the infield in, but King got Hernandez swinging for the second out and whiffed Renfroe to prevent further damage.
The Yankees threatened in the sixth, as Gardner followed Urshela’s single with a double to right. That sent Urshela to third and knocked Pivetta out of the game.
Judge came up against another former Met, Hansel Robles. His first pitch went to the backstop, sending Urshela home for the Yankees’ first run, and moving Gardner to third.
But Judge grounded to third and Gardner, trying to score though the infield was in, was out at the plate thanks to a strong throw from Rafael Devers.
Rizzo ended the threat with a popout, leaving the Yankees down by a run.
Stanton and Joey Gallo led off the seventh by each walking on four pitches against Houck.
The right-hander finally threw a strike to Gleyber Torres and then got him to hit into a double play, with Stanton moving to third on the play.
Sanchez then struck out on three pitches, stranding Stanton.
