Alvarez homer lifts Astros over Mariners again for 2-0 lead in ALDS

With every big swing, Yordan Alvarez is owning this October.

A ferocious comeback for the powerful slugger who struggled in Houston's loss to the Atlanta Braves in last year's World Series.

Alvarez and his mighty bat did it yet again, launching a go-ahead, two-run homer in the sixth inning off Seattle ace Luis Castillo that lifted the Astros over the Mariners 4-2 on Thursday for a 2-0 lead in the AL Division Series.

This performance comes after he batted just .100 (2 for 20) with no homers and six strikeouts as Houston lost the World Series in six games.

With all of baseball talking about his hitting, the 25-year-old was asked how he'd describe himself at the plate.

"I would say intelligent," he said in Spanish through a translator. "Whenever I go up to the plate I try to visualize what the different kind of results that I could get up there when I'm hitting. If everything goes according to plan we'll get a positive result."

He's already had plenty of those this postseason.

Castillo, acquired from the Reds near the trade deadline and coming off 7 1/3 innings of shutout ball against Toronto in the wild-card round, gave up an early home run to Kyle Tucker but little else as he took a 2-1 lead into the sixth.

But with two outs, Jeremy Pena singled on a blooper that fell in between second baseman Adam Frazier and centre fielder Julio Rodriguez. Castillo bent down and slapped his legs in disappointment as he watched the ball drop in shallow centre.

"We just have to communicate a little better," Frazier said.

'He's one of the greatest hitters we have right now'

That brought up Alvarez, who hit a 98 mph pitch tailing away to the opposite field, into the short porch in left to put the Astros on top 3-2.

"He threw a ball three or four inches off the plate and he hits a home run to the opposite field," manager Scott Servais said. "He's that kind of talent."

Added Rodriguez: "He's one of the greatest hitters we have right now."

"My family being here, I think that it does give me a lot of peace of mind having them here," he said. "Yeah, definitely I do think that it's helped my performance."

Alvarez is the first player in postseason history to hit multiple go-ahead homers in the sixth inning or later with his team trailing.

There were two outs and a runner on first in the eighth when Seattle had surely seen enough of Alvarez leaving the yard. The Mariners intentionally walked him and Alex Bregman made them pay, adding some insurance when he singled to make it 4-2.

"That was some Barry Bonds-type stuff there," said Baker, who managed Bonds in San Francisco. "That's the ultimate respect."

Houston starter Framber Valdez had a solid start, allowing four hits and two runs in 5 2/3 innings. He had a different look than he did in his last postseason appearance after he and fellow pitcher Luis Garcia both got hair extensions this season.

Hector Neris got the win after getting the last out of the sixth inning to escape a bases-loaded jam. Bryan Abreu got the first two outs of the seventh before Rafael Montero came in and threw 1 1/3 scoreless innings.

Ryan Pressly walked the leadoff batter in the ninth before J.P. Crawford lined into a double play. Rodriguez doubled after that, but Pressly struck out Ty France for the save. The Astros won despite issuing seven walks overall.

Seattle to host 1st home playoff game in 21 years

The Mariners will head back to Seattle for Game 3 Saturday in a huge hole in the best-of-five series as they host their first playoff game in 21 years.

Alvarez has carried the Astros early in this division series, shouldering such a load that Houston catcher Martin Maldonado asked Alvarez after Game 1 if his back was sore because "you carry us as a team." The slugger who's been criticized for poor defence in the past has been making big plays in left field, too.

Alvarez grabbed a sharp liner hit by Eugenio Suarez to end the seventh. In the opener, he fielded a single by Suarez in the fourth and threw a perfect strike to Maldonado, who tagged out France at the plate.

Castillo yielded five hits and three runs with seven strikeouts in seven innings.

Crawford doubled with two outs in the third. But second baseman Jose Altuve made a leaping throw after fielding a sharp grounder hit by Rodriguez that just beat him to first base to end the inning.

Suarez walked with one out in the fourth and Mitch Haniger doubled. Carlos Santana then hit a one-hopper that Valdez fielded cleanly toward the third base side, but his throw home was offline for an error that allowed Suarez to tie it at 1-all.

Santana was out on the play after getting caught in a rundown. Haniger scored when Dylan Moore singled to put the Mariners up 2-1.

Valdez walked Haniger on a full count with two outs in the sixth, Santana doubled and Moore drew a walk to load the bases and chase Valdez. Neris took over and retired Cal Raleigh on a groundout to escape the jam.
