WEST SACRAMENTO, Calif. — Looking back on it, the most remarkable feat accomplished here Sunday afternoon may have been that A’s lefty Jacob Lopez somehow retired the first six Yankees of the game.

From there, the next 12 Yankees reached in order — pushing 10 runs across — before they made another out, and their stupefying rally did not stop there.

By the time the 43-minute beatdown of a third inning was over, the Yankees had sent 18 men to the plate, with 15 of them reaching and 13 of them scoring — one shy of a franchise record that has stood since 1920.

They racked up 11 hits — incredibly, none of them leaving the park — and four walks, seeing 75 pitches from three pitchers. Anthony Volpe, Ben Rice and Cody Bellinger each had two hits in the inning, with Rice driving in four runs.

In the process, the Yankees turned a three-run deficit into a 10-run lead, sucking the life out of the A’s pitching staff one painstaking at-bat at a time on the way to a 13-8 win.

Amazingly, in the eight innings outside of the ridiculous third, the Yankees only had a single base runner: a leadoff walk in the sixth inning that was erased by a double play.

In other words, the A’s faced the minimum for eight innings but faced a parade in the third.

Will Warren, who had to jog to the bullpen during the second pitching change of the third inning to warm up because it had been so long since he last threw a pitch, did not allow the A’s (28-31) to return serve.

The right-hander took the gaudy run support and cruised across six innings, allowing only three unearned runs as the Yankees (36-23) wrapped up a 5-1 road trip in style.

The 12 straight Yankees to reach base to start the third inning matched a franchise record from 1949.

Phil Rizzuto led off that rally with a walk before the likes of Joe DiMaggio and Yogi Berra piled on.

On Sunday, it was Volpe who got it going with a bloop single off Lopez after the Yankees had not even hit the ball out of the infield through the first two innings and trailed 3-0.

Former A’s utilityman Max Schuemann and Austin Wells followed with walks to load the bases for Paul Goldschmidt, who roped an RBI single to make it a 3-1 game.

Rice came up next and smoked a two-run double down the line to tie the game before Aaron Judge blooped a single into center field for the 4-3 lead.

The station-to-station action was only just beginning, as Bellinger singled to reload the bases, at which point the A’s put Lopez out of his misery and brought in Michael Kelly, who was not much better.

Kelly immediately walked José Caballero on four pitches to force in another run — the same way the Yankees scored three runs in a ninth-inning comeback that fell just short in Saturday night’s loss.

Grisham then fisted a two-run single to center field, and after he and Caballero pulled off a double steal, Volpe poked his second single of the inning up the middle to make it 8-3.

Schuemann added to his nice homecoming with a two-run double, pushing the lead to 10-3 before Goldschmidt struck out looking for the first out of the inning — on a pitch out of the zone that he chose not to challenge.

Rice, who fell a triple short of the cycle here Friday night, kept the rally going by drilling a triple to right field, scoring two more runs.

After Judge struck out, Bellinger capped off the scoring with a single that made it 13-3. Caballero followed with a single of his own.

The A’s then made their second pitching change of the frame, and Jack Perkins finally ended the offensive onslaught by getting Grisham to fly out — evoking a Bronx cheer from the crowd that may have needed the seventh inning stretch by the middle of the third.

The Yankees came close to making history, becoming the first team since the Red Sox in 2009 to have 12 straight batters reach safely to start an inning.

The MLB record since 1920, owned by the Tigers, is 14 straight.

The A’s made things semi-interesting in the seventh inning when Tim Hill got some work in and gave up four runs on a pair of homers.
