OAKLAND -- The Yankees punched their ticket into the postseason during a successful West Coast trip, including a wet and wild celebration that toasted their return to the playoffs following a one-year absence. They¡¯re jetting home with another party on deck.

Aaron Judge hit his Major League-leading 55th home run, Jasson Domínguez cracked a two-run shot and Gleyber Torres also went deep as the Yankees bid a pleasant farewell to the Oakland Coliseum, completing a series sweep of the Athletics with a 7-4 victory on Sunday afternoon.

With the victory, the Yankees increased their American League East lead to six games over the Orioles, who will be at Yankee Stadium for a three-game series beginning Tuesday. Any Yankees victory over Baltimore during that set would clinch the division for New York.

¡°It¡¯s going to be rocking,¡± Judge said. ¡°It¡¯s been rocking all summer long, and I don¡¯t expect that to change, especially with what we have coming down to the wire here.¡±

The Yanks also have a 2 1/2-game lead over the Guardians for the AL¡¯s No. 1 seed, which guarantees home-field advantage throughout the AL playoffs.

¡°We¡¯re focused,¡± manager Aaron Boone said. ¡°I think everyone in that room knows what¡¯s at stake and what the mission is, where we¡¯re at in the calendar and the opportunity in front of us. I think guys are just ready to do what we¡¯ve got to do to win ballgames and give ourselves a chance come October.¡±

Luis Gil started for the Yankees, permitting four runs and five hits over 5 1/3 innings to earn his 15th victory, including his third straight decision.

¡°The focus is to keep the team in the fight,¡± Gil said through an interpreter. ¡°We¡¯re trying to win as many games as possible. To give my team a shot to win the game, I think that¡¯s the important thing there.¡±

The Athletics jumped out to an early lead, but Dom¨ªnguez tied the game with a second-inning homer off starter Joey Estes, the top prospect¡¯s second big league blast of the season.

¡°That¡¯s what you¡¯re trying to do, to contribute to the team in one way or another,¡± Dom¨ªnguez said. ¡°It means a lot to be able to help the team in any way.¡±

Judge slugged a solo shot in the third inning, his second in as many games, extending his Major League lead over the Dodgers¡¯ Shohei Ohtani (53). Judge also doubled and walked twice; his 55 homers are the fifth-most in a single season by a Yankee, ahead of Babe Ruth (1920, ¡¯28), Mickey Mantle (1961) and Alex Rodriguez (2007).

¡°Double nickels,¡± Boone said. ¡°I gave him the game ball and I¡¯m like, ¡®Oh, geez, he was on base four times today.¡¯¡±

Athletics manager Mark Kotsay said that he considers Judge¡¯s prowess close to Barry Bonds in terms of his power and on-base ability.

¡°He impacts the game not just with the ability to drive the ball out of the ballpark, but he gets on base and is a pretty good baserunner,¡± Kotsay said. ¡°We saw that late in the game. Defensively, he goes and gets it. He¡¯s one of the best players in the game right now. He¡¯s got my vote for MVP this year.¡±

The Yanks¡¯ final series in Oakland was bittersweet for Judge, who grew up about 80 miles away in Linden and said he attended games at the Coliseum with his future wife, Samantha.

¡°It¡¯s definitely sad. I had a lot of great memories here as a player,¡± Judge said. ¡°I came here a couple of times as a kid, so I¡¯ll reminisce on that a little bit. There¡¯s a lot of history in this building, going back to the ¡¯70s, what they were able to do here three years in a row [winning the World Series from 1972-74). A lot of special players played here, and getting a chance to be on that same field is definitely something I won¡¯t forget.¡±

Torres¡¯ 15th homer of the year highlighted a two-run fifth. Giancarlo Stanton and Austin Wells added run-scoring doubles before Luke Weaver nailed down a five-out save, his fourth since stepping into the closer¡¯s role.

¡°We¡¯re just pressuring them from every spot, with tough at-bats,¡± Boone said. ¡°It¡¯s really good to see when we¡¯re putting pressure on them and mixing in the long ball. That¡¯s a recipe for some crooked numbers.¡±

The Yankees won five of six games on their final road trip of the regular season, which included a playoff-clinching celebration following their Sept. 18 victory at Seattle. They¡¯ve got their sights set on much more.

¡°We weren¡¯t even close to the playoffs last year, but this year, every game matters,¡± Dom¨ªnguez said. ¡°Everything that you do matters.¡±
