Houston Astros reach the World Series for the 4th time in 6 years by sweeping the New York Yankees in the ALCS

NEW YORK — Yordan Alvarez and Alex Bregman delivered big hits and the Houston Astros advanced to the World Series again, finishing a four-game sweep of the New York Yankees in the American League Championship Series with a 6-5 victory Sunday night aided by another defensive gaffe from the Yankees.

Taking advantage of a costly error by second baseman Gleyber Torres to produce the go-ahead rally in the seventh inning, the Astros won their second consecutive pennant and fourth in six years.

Rookie shortstop Jeremy Peña hit a three-run homer off ailing Yankees starter Nestor Cortes to help the AL West champions overcome an early 3-0 deficit.

The Astros will open the World Series at home Friday night against Bryce Harper and the wild-card Philadelphia Phillies, who beat the San Diego Padres earlier in the day to close out the best-of-seven National League Championship Series in five games.

It was the first time since 1992 both pennants were decided on the same day.

After losing to the Atlanta Braves in last year’s World Series, the Astros earned the fifth pennant in franchise history and another chance at their second World Series championship.

The team’s 2017 title was tainted by a cheating scandal.

With the playoffs expanded to 12 teams this year, the Phillies became the first third-place team in baseball history to reach the World Series.

The Phillies went 87-75 during the regular season, while Bregman and the Astros finished 106-56 under manager Dusty Baker, seven games better than any other AL team.

“Hey, these are the greatest guys I’ve ever been around,” the 73-year-old Baker said in a postgame celebration.

Back in the leadoff spot, Harrison Bader had three hits and scored three times for the Yankees. He connected off winning pitcher Hector Neris for his fifth home run of these playoffs, giving the Yankees a 5-4 lead in the sixth.

They couldn’t hold it when they absolutely had to.

Peña hit what should have been an inning-ending double-play ball to Torres in the seventh. But his flip to second base went wide of shortstop Isiah Kiner-Falefa as the crowd of 46,545 groaned, and the Astros had two on.

Alvarez singled home the tying run on the next delivery from losing pitcher Jonathan Loáisiga, and Bregman put Houston ahead with an RBI single off Clay Holmes.

It was the sixth error of this postseason for the Yankees, who also gave the Astros a pivotal gift in Game 3. Chas McCormick hit an early two-run homer off New York ace Gerrit Cole after Bader, a Gold Glove outfielder, dropped a two-out fly when he nearly collided with Aaron Judge in right-center.

Bryan Abreu, Rafael Montero and Ryan Pressly shut the door with perfect relief. Pressly retired Judge on a comebacker for his third save of the series, sending the Astros rushing out of the dugout for ecstatic hugs and handshakes on the infield.

Moments later, a throng of orange-clad Houston fans chanted “sweep! sweep!” behind the team’s third-base dugout in a mostly empty Yankee Stadium.

Handed an early 3-0 lead, Cortes walked No. 9 batter Martín Maldonado to start the third and fell behind 2-1 on slumping Jose Altuve.

Something wasn’t right. Yankees manager Aaron Boone and head athletic trainer Tim Lentych went to the mound for a quick check on Cortes, who initially remained in the game.

But he walked Altuve, marking the first time the All-Star lefty issued consecutive free passes this season. And eight pitches after the mound visit, Peña launched a 3-1 slider into the left-field seats to tie it.

That was it for an ailing Cortes, who exited with a left groin injury that he apparently aggravated. He was sidelined from Aug. 22 through Sept. 7 with a strained left groin.

Alvarez doubled off Wandy Peralta and went to third when Peralta got nailed by Kyle Tucker’s line drive that went for an infield single with one out. Yuli Gurriel bounced an RBI single through an open right side to put Houston ahead 4-3, but Peralta prevented further damage.

Needing a win to extend their season, the Yankees got off to a fast start in the first after an 84-minute delay due to a threat of rain. Giancarlo Stanton laced an RBI single off starter Lance McCullers Jr., and Torres blooped a run-scoring single into center.

That ended New York’s scoreless streak at 14 innings. Houston had gone 19 innings without permitting an earned run.

Anthony Rizzo’s two-out RBI double made it 3-0 in the second, but Stanton struck out with runners at second and third. Rizzo also delivered a two-out RBI single that tied it 4-4 in the fourth.

McCullers, who closed out the Yankees with 24 straight curveballs in Game 7 of the 2017 ALCS, lasted five innings. He gave up four runs — three earned — and eight hits.
