LOS ANGELES — If the Houston Astros had plenty on their minds — and the weight of history on their backs — it hardly seemed like a burden when they arrived at Dodger Stadium on Wednesday.

A franchise that hadn’t won a championship since joining the major leagues in 1962 faced the daunting task of playing Game 7 of the World Series in front of a boisterous crowd supporting the Dodgers.

But the Astros appeared oddly at ease. Manager A. J. Hinch kept his pregame news conference light, shortstop Carlos Correa and second baseman Jose Altuve lounged on the grass as they awaited batting practice, and the scene inside the clubhouse was reassuring: Music played, game plans were reviewed and no one was staring into his locker.

“I was thinking, well, let’s see how everyone looks,” said Carlos Beltran, one of the veteran leaders. “If I feel like we’re tight, we might need to say something.”
