It can often sound like a cliche when players talk about how they feed off a crowd’s energy. But in the case of the Red Sox and Fenway Park, it seems like the fans are creating a real home-field advantage this postseason.

Behind another electric sellout crowd Monday, the Red Sox grabbed hold of the game early with Kyle Schwarber’s second-inning grand slam en route to their 12-3 victory over the Astros as they took a 2-1 lead in the American League Championship Series. The crowd was loud and deafening at times — especially after Schwarber’s grand slam.

“That gave me a headache, and I loved it,” Schwarber said. “I loved every second of it. Like I said, this is what you live for, right? This is it. You know, obviously, we still have steps to where we want to be, but to have the atmosphere like that, we feed off that, and that’s only going to help us be better, and it’s going to help us to where we want to be, but we still got to take it a game at a time.”

The Red Sox are 4-0 at home in this postseason, all in front of electric crowds, each one seemingly louder than the last one.

Schwarber is in a unique position. He played with the Cubs to begin his career — winning a World Series in 2016 — and the crowds at historic Wrigley Field were always great, too. He was traded to the Red Sox at this year’s trade deadline, and he’s certainly embraced Boston. He was even wearing a Waltham Hawks T-shirt after Monday’s win, an appreciation to the “Kyle from Waltham” joke created by the popular Section 10 podcast.

Schwarber is cherishing every moment at Fenway because he knows how unique it is.

“It just brings a smile to your face when you just think about it, right?” Schwarber said. “Just the atmosphere. It’s something that you want. You don’t realize how lucky you are as a player to have a fanbase like this. I was lucky. I had a great fan base in Chicago for how many years I was there, and then to be able to walk into another great fan base, you can’t take that for granted.

“You cannot take that for granted because you go to — go and play games in other places and to have — no offense, but just to not have the seats full, right, it’s a different game. Walking into a place where the fans, they care about you, win or lose. They’re going to be there, and they’re going to let you know, right? Don’t take that for granted because it’s very special to have.”
