CHICAGO -- Anthony Rizzo squeezes the final throw from Starlin Castro, and in the name of Gabby Hartnett, Mark Grace, Leo Durocher and the black cat, Steve Bartman and the Billy Goat, and Ron Santo, it is over. Once and for all, the 107-year wait is over. The Chicago Cubs are the champions of the baseball world in 2015 and a city is live-streaming hysteria, in a good way. There are hugs all around. Catcher Miguel Montero leaps into the arms of closer Hector Rondon, and Rizzo, who stuffs the historic baseball into his back pocket on his short sprint to the mound, grabs both guys with a bear-cub hug, and then a tidal wave of teammates crashes into them. Montero is at the bottom, hearing all the screams and whoops (he's not adding to them, because he's out of breath). Manager Joe Maddon turns to shake the hand of pitching coach Chris Bosio, in a measured been-there, done-that moment, but that isn't nearly enough for Bosio and the other coaches, who all but tackle Maddon in the corner of the home dugout. An army of Chicago police, some of them mounted on horses, are charging down the foul lines and in front of the ivied walls to keep order. The flag with the retired number No. 14 of Ernie Banks snaps in the wind above them. This is a moment built over decades, over disappointments, over disasters and over a long season. The Cubs had played the first game of the 2015 season amid the skeleton of an active construction site, and that first night demonstrated the promise of what finally was possible: Lester's six efficient innings in his Chicago debut and the big late-inning hit by Jorge Soler, a rising star overshadowed in March by the moonshot homers of Kris Bryant. Earlier this spring, Maddon compared Soler's ability to square up a ball, in or out of the strike zone, to Vladimir Guerrero's, and on that first night, Soler demonstrated that by dumping a line drive into short center field, chasing home the lead run. That night, it felt like an opening statement, bolstered not long after by the arrival of Bryant, on April 17, on a sunny Friday at Wrigley. The ovation that greeted him was so loud that James Shields, the starter for the opposing San Diego Padres, stepped off the mound deferentially to give Bryant a moment to acknowledge the fans. In Bryant's third plate appearance, he wasn't so deferential, launching -- that's the only verb that properly describes the trajectory of Bryant's homers -- the ball high over the construction site, over the men in yellow hats, over Waveland Avenue. There may have actually been 30,000 in the old ballpark at that moment, but in 50 years, 3 million might claim to have been there. The quick start gave way to the difficulty of May, the early-season injuries, the mistakes and misplays that made the 2015 Cubs seem more like the century of their predecessors. But a series against the Pirates early in August was a turning point. After Bryant was hit by a pitch, and there was seeming retaliation by Cubs reliever Pedro Strop, the benches emptied, and Maddon screamed at Pirates manager Clint Hurdle. The Cubs -- with Rizzo and Castro mashing, with Soler building a season worthy of MVP consideration -- began chewing up opponents, climbing in the standings. When the playoff spot was clinched on the last weekend of the regular season, Theo Epstein, the Cubs' president of baseball operations, hovered outside of the vortex of celebration in the home clubhouse, but spotted Bryant and grabbed him by the arm. "You were made for this," Epstein told the young slugger. "This doesn't happen without you." Lester's dominance in the wild-card game inspired the Cubs for the next rounds of the playoffs, for that incredible ninth-inning comeback in the league championship series, finished off when pinch-runner Javier Baez raced home from first on the flair down the right-field line. The Cubs hit the finish line in the World Series as Castro fields the two-hopper, pauses a moment before whirling the last throw to Rizzo. And it's over; the long wait is over. No matter what Soler and Bryant and Rizzo do in the rest of their careers, they are Chicago legends, joining Butkus, Ditka and Belushi. Maddon's money is no longer any good in this town, and Epstein, having conquered the K2 and Everest of baseball championship droughts, in Boston and Chicago, can get to work on his Cooperstown speech. Lester grabs a bottle from the bin in the home clubhouse and turns it upside down over Maddon's head, and with the river of champagne running over his face, Maddon can't see any more, the figures around him losing their definition … Alas, it's only just a dream -- for now. But these visions are more vivid than they have been for many years; they're within reach, within the realm of possibility. The Cubs open their season against the St. Louis Cardinals on Sunday night at 8 ET, with Lester throwing the first pitch for the Cubs while opposing Cardinals ace Adam Wainwright.
