Ending more than a century of flops, futility and frustration, the Chicago Cubs won their first title since 1908, outlasting the Cleveland Indians 8-7 in 10 innings of a Game 7 thriller early Thursday.
They even had to endure an extra-inning rain delay to end the drought.
All-Star closer Aroldis Chapman blew a 6-3 lead with two outs in the eighth when Rajai Davis hit a tying, two-run homer.
But the Cubs, after tormenting their fans one more time, came right back after a 17-minute rain delay before the top of the 10th.
Series MVP Ben Zobrist hit an RBI double and Miguel Montero singled home a run to make it 8-6. Davis delivered an RBI single with two outs in the bottom half, but Mike Montgomery closed it out at 12:47 a.m., and the celebration was on.
World Series favorites since spring training, Chicago led the majors with 103 wins this season.
Zobrist got a Series-high 10 hits, a year after he helped the Royals win the championship. Zobrist was among the players brought to the Cubs by Theo Epstein, the baseball guru who added another crown to his collection. He also assembled the Red Sox team that broke Boston's 86-year drought by winning in 2004.
Dexter Fowler homered on Corey Kluber's fourth pitch of the game, 23-year-old Javier Baez and the 39-year-old Ross - set to now retire - also went deep for the Cubs, who led 5-1 in the fifth inning and 6-3 in the eighth.
Chapman wound up with the win, and Montgomery got one out for his first save in the majors.
Bryan Shaw, who gave up a leadoff single to Kyle Schwarber in the 10th, took the loss in just the fourth Game 7 that went to extra innings.
Albert Almora Jr., pinch-running for Schwarber, alertly took second on Bryant's long fly to center. Rizzo was intentionally walked, and Zobrist slapped an opposite-field double past a diving third baseman Jose Ramirez. Montero singled to make it a two-run lead.
Then in the bottom half, Carl Edwards Jr. struck out Mike Napoli, Ramirez grounded out, Brandon Guyer walked and Davis hit an RBI single. Montgomery took over, and helped set off a wild celebration on Chicago's North Side.
