COOPERSTOWN, N.Y. — Nearly every city and town in America has a Main Street. But there is no Main Street in America quite like this town’s Main Street on Hall of Fame Weekend.

You never know who you are going to run into as you make your way up to the Baseball Hall of Fame.

Step out of Sal’s Pizzeria, you see Hall of Famer and former Yankees closer Goose Gossage, who was never afraid to throw the high hard one, or speak his mind, going back to his days of closing games for The Boss.

Gossage wants to make one thing clear regarding Mariano Rivera, who will be inducted next year into the Hall of Fame.

“I love Mariano,’’ Goose told The Post on Friday. “I will be here for his induction. I wouldn’t miss it.’’

During spring training, Gossage said it was insulting to be compared to Rivera and Aroldis Chapman because they are one-inning closers. Gossage comes from the era when closers were asked to be their own setup men, too, sometimes going three innings to finish a game.

“I just take offense to the fact they named the American League and National League relief awards after these guys, it’s not right, it’s a shun to us,’’ Gossage said of the Mariano Rivera AL Reliever of the Year Award and Trevor Hoffman NL award, doubling down on his spring comments.

Hoffman will be inducted into the Hall on Sunday along with Chipper Jones, Vladimir Guerrero, Jim Thome, Alan Trammel and Jack Morris.

“Mariano is the greatest one-inning pitcher of all time,’’ Gossage said. “It’s apples and oranges. When I was trying to get into the Hall of Fame [reporters] would call me and I’d say these guys are so dominant in their one-inning roles they forgot what we used to do.’’

That is true.

“Trevor, like Mariano, is a great guy too and do they belong? Absolutely,’’ Gossage said.

“This is not a knock against Mariano, it’s a knock about how he was used,’’ Gossage added, pointing to three-run leads and one-inning saves. “If everybody in that bullpen can’t save a three-run lead in one inning they shouldn’t be in that bullpen.’’

A little farther up the road in a store called Safe At Home, Pete Rose, who probably will never get into the Hall of Fame, offered up thoughts on the race in the AL East between the Red Sox and Yankees.

He has known the Boone family a long time.

“I played with Bob Boone for five years, I knew Ray, his dad,’’ Rose said. He joked that Yankees manager Aaron Boone, “does a hell of a [hitting imitation of] Pete Rose.’’

Rose, 77, then launched into his batting stance.

“Every team that puts the ball in play a lot goes to the World Series, Houston won the World Series, they put the ball in play a lot,’’ said the Hit King. “Boston puts the ball in play a lot, that’s why I like Boston right now better than the Yankees.They’ve got potential batting champions and they have potential home run champions. The Yankees have potential home run champions and a great bullpen.’’

As for the state of the game today, Rose said: “I think there are a lot of good players out there. Secondly, I don’t think there are a lot of really good teams. There are more bad teams than good. Every hit is a home run, you get tired of watching the highlights. And the number of ballparks it’s a joke to pitch in: Philadelphia, Baltimore, Houston, Colorado and Arizona. And the baseball is juiced.’’

And a little farther down the street stood former Mets slugger Darryl Strawberry.

Straw had some thoughts on the current Mets.

“I really want them to do well, for the fans. Get it together and going in the right direction. I’d like to see them develop the farm system a little bit more and that’s what Omar [Minaya] can do,’’ Strawberry told The Post. “That’s where you get your players. Omar did a phenomenal job when he was there developing the farm system.’’

As for Jacob deGrom, Strawberry was adamant: “I’d keep him. He’s the heart and soul of the rotation.’’
