HOUSTON (AP) — Yordan Alvarez hit a towering, go-ahead homer and the Houston Astros clinched their second World Series title in six seasons and got Dusty Baker his first crown as a manager, beating the Philadelphia Phillies 4-1 in Game 6 on Saturday night.

Alvarez blasted a three-run drive in the sixth inning immediately after Phillies starter Zack Wheeler was pulled with a 1-0 lead. As Alvarez’s 450-foot drive disappeared, Astros starter Framber Valdez jumped and wildly screamed in the dugout as fans in the crowd of 42,948 went into a frenzy waving their orange rally towels.

“When I was rounding second base, I felt the whole stadium moving,” Alvarez said through a translator.

Baker finally got his first title in his 25th season as a manager, the past three since being hired by the Astros to help the team regain credibility after the sign-stealing scandal that cost manger A.J. Hinch and general manager Jeff Luhnow their jobs, and made Houston the most reviled team in baseball.

The 73-year-old Baker, who had been to the World Series twice before as a skipper, is the oldest championship manager in any of the four major North American sports. It came 20 years after a near-miss, when he came within five outs of winning the championship while guiding the San Francisco Giants.

Baker also led the Chicago Cubs, Cincinnati Reds and Washington Nationals to the postseason before coming to Houston in 2020.

“What’s next? I said if I win one, I want to win two,” Baker said afterward.

Houston’s coaching and training staffs circled around Baker after Nick Castellanos flied out to end it, jumping up and down, and chanting “Dusty! Dusty! Dusty!” in the dugout before they joined the players on the field.

Astros rookie shortstop Jeremy Peña was the World Series MVP after getting another key hit, a single to set up Alvarez’s drive.

The 25-year-old star born in the Dominican Republic also won a Gold Glove award and AL Championship Series MVP — Peña is the first hitter to win those three awards in a career, and he did it all in his first season, per OptaSTATS.

Alvarez’s homer cleared the batter’s eye in straightaway center, the backdrop that extends 40 feet above the field. It was the first time the Cuban slugger connected since the first two games this postseason.

“This time what I did, I just tried to stay a little bit calm, select a good pitch to swing at,” he said. “And that’s what I did.”

Christian Vázquez added an RBI single later in the inning to make it 4-1.

Valdez earned his second win of this Series. He had been in the dugout only a few minutes after throwing his 93rd and final pitch while striking out nine over six innings.

But the lefty walked off the mound with the wild-card Phillies up 1-0 on Kyle Schwarber’s solo homer leading off the sixth.

Schwarber, who hit his third home run in the past four games, rounded the bases waving his raised empty hand in the same motion as the fans with their towels.

“Obviously, they threw a punch, and we did what we’ve done all year: We came right back and threw a haymaker,” said Houston ace Justin Verlander, the likely AL Cy Young winner who in his ninth career World Series start finally got his first victory in Game 5.

But by the time Schwarber batted in the eighth inning, the NL’s home run leader was reduced to bunting, trying for a hit to stir a dormant Phillies offense. His bunt went foul with two strikes, resulting in a strikeout.

In the sixth, Houston got two runners on base against Wheeler for the first time in the game, when Martín Maldonado was hit by a pitch, Jose Altuve grounded into a forceout and Peña singled.

Phillies manager Rob Thomson went to left-handed reliver José Alvarado to face the lefty slugger for the fourth time in the series. Alvarez had popped out twice and been hit by a pitch the first three times.

Wheeler finished with 70 pitches, allowing two runs on three hits over 5 1/3 innings. He struck out five and walked one.

“I thought Wheels still had really good stuff. It wasn’t about that. It was just I thought the matchup was better with Alvarado on Alvarez at that time,” Thomson said.

And Alvarado had allowed only three homers to left-handed hitters in his six big league seasons, until his 2-1 pitch, when Alvarez crushed the 99 mph sinker.

Alvarez hadn’t homered since Game 2 of the AL Division Series against Seattle, when his two-run shot in the sixth inning put them up to stay. That came after his game-ending, three-run shot in Game 1 for an 8-7 win.

“It’s kind of a dirty inning and I thought, I mean, going into the series it was always kind of Alvarado on Alvarez,” Thomson said. “It was the sixth inning and I felt like the normal back end of the bullpen guys could get through it.”

Houston won an American League-best 106 games and reached its fourth World Series during a span in which it made it to the AL Championship Series six seasons in a row. The Astros made their only other World Series appearance in 2005, while still in the National League, and were swept in four games by the Chicago White Sox.

This was their third ALCS and second consecutive World Series since former Astros pitcher Mike Fiers revealed after the 2019 season, when he had been gone from Houston for two years since being part of their 2017 championship, that the team had used a camera in center field to steal signs and signal hitters on which pitches to expect by banging on a garbage can.

Philadelphia was 22-29 when Joe Girardi was fired in early June and replaced by bench coach Thomson, the 59-year-old baseball lifer getting his first chance as a big league manager. He was on the Yankees’ big league staff for 10 seasons with Girardi, and was part of their last World Series and title in 2009 — which, coincidentally, they won by beating the Phillies.

The Phillies finished the regular season 65-46 under Thomson, their 87 wins good for the sixth and final spot in the NL playoffs, on way to their first World Series since 2009.
