CHICAGO – Sunday dawned subdued over Wrigleyville.

It rolled over into Monday in a state of semi-controlled chaos.

The Cubs are still alive, beating the Indians 3-2 at Wrigley Field in Game 5, the best-played game of the World Series by both teams.

After two full days of fans flocking to Wrigley shortly after sun-up to start taking selfies in front of the iconic marquee — “Wrigley Field Home of the Cubs, World Series …” -- and clogging the streets and queuing up outside of every pub and grill in the neighborhood before noon, the Sunday crowd arrived late and mellow.

Maybe they spent the morning in church, praying for a miracle.

Maybe their prayers worked.

Or maybe the Cubs didn’t need a miracle so much as they needed to play good baseball. Which they did.

For the first time since Game 6 in 1945, they won a World Series game at Wrigley Field, and they’re headed back to Cleveland with a chance to win the elusive championship .

The citizens of Cubs World arrived Sunday, carrying the baggage of fatalism that history has packed for them for more than a century. A middle-aged fellow stood on Addison, across the street from the ballpark, playing his guitar and singing the victory anthem, “Go, Cubs, Go!” But it was almost melancholy, and hardly anyone sang along.

Within a matter of hours, everything changed.

The crowd roared to life in the first inning, as starter Jon Lester mowed down the first three Indians with strikeouts. The fans grew quiet after a Jose Ramirez home run put the Indians up, then exploded back to life when Kris Bryant homered to tie it in the fourth. And when Anthony Rizzo, Ben Zobrist, Addison Russell, Javy Baez and Ross punched in two more runs for the lead …

As manager Joe Maddon might say, it got crazy, man.

By the time it was over, the Wrigley Chorale was belting out “Go, Cubs, Go!” at O’Hare runway levels, and hope had been resurrected.

And after exiting the field, the players came back out to acknowledge the crowd.

“It was nice to give these fans something to cheer for and hear them sing ‘Go, Cubs, Go!’” Ross said.

Triumph might be possible. For real.

Of course, victory didn’t come easy, and the tension that was utterly missing from the first four games decided to make up for lost time.

After Bryant homered to tie the game in the fourth, Rizzo doubled off the wall in right field. Zobrist then kept the line moving with a single to put runners on second and third, Russell drove in Rizzo with a swinging bunt for a base hit, Baez broke his slump by bunting to load the bases, and then came Ross’s turn.

In what turned out to be his final at-bat in Wrigley Field, Ross hit a long fly to center field, driving in Zobrist with what proved to be the decisive run.

Then came the real heart-stopping stuff as both managers went early to their closers.

Remember the days when those ace, game-ending relievers used to throw two and three innings? They’re back.

Indians skipper brought in his save man, Cody Allen, even though his team was down a run. And Cubs manager Joe Maddon did the same, going to Aroldis Chapman with one out in the seventh.

Chapman gave up one single and hit a batter, but he struck out four en route to an eight-out save.

“It’s World Series time,” Ross said. “Everybody’s gotta do the best they can. Their guys are throwing multiple innings, and it’s nice to see Chappy match them.

“Chappy was huge. KB was huge. Ben Zobrist had phenomenal at-bats all night. And how about Javy’s bunt?”

Yes, how about all of that?

In 24 hours, this place went from “No, Cubs, No” to “Go, Cubs, Go!”

Nine wins down, two to go in the march to rewrite history. And suddenly, anything is possible again.
