Los Angeles now hosts Atlanta in the best-of-five NL Division Series beginning Thursday.
Walker Buehler will be the Dodgers starting pitcher.
The soft-spoken 24-year-old from Lexington, Kentucky, has been so steady of late that manager Dave Roberts had no qualms about giving Buehler the ball for the crucial game that helped decide the Dodgers' postseason fate.
Colorado had another impressive individual performance earlier in the week when German Marquez began a start against Philadelphia with eight straight strikeouts, tying a record.
Yasiel Puig will start in place of the heavy-hitting Matt Kemp, while Kike Hernadez will get the start at second place and bat eighth over the veteran Brian Dozier, who hit a big two-run homer yesterday.
Anthony Rizzo scored three runs and went 4-for-4 with two doubles, two singles, one RBI and one walk to lead the Cubs' offense.
Dodgers closer Kenley Jansen surrendered home runs to Nolan Arenado and Trevor Story in the ninth before he retired the next three hitters to secure the win. Monday's losers will be back on the field Tuesday, forced to face off in the single-game elimination NL Wild-Card Game. It was a near tie between the Chicago Cubs, Milwaukee Brewers, Colorado Rockies, Los Angeles Dodgers and St. Louis Cardinals. Every team in both the NL and AL has a better record than the Dodgers except for Cleveland who finished with the same overall record but more victories within the division. That was the first hit allowed by six Oakland relievers and the first hit by the Angels since the third inning.
The last team to win a tiebreaker game and go on to win the World Series is the 1978 Yankees.
Joc Pederson doubled to deep right-center leading off the fifth. The Dodgers had never won more than two consecutive division titles before the current run. But the Rockies won nine times in 10 games to force a game 163, part of the first season in major league history with a pair of tiebreakers.
In the other one-game playoff held the same day, the Brewers beat the Cubs 3-1 for their first NL Central title since 2011.
But bad calls are nothing new to the NFL, part and parcel with the league's decisions on everything from domestic violence to the health of its own players to fumbled responses the exercising of first amendment rights, so missing a critical call at a pivotal moment in a regular season game kind of pales in comparison.
MILWAUKEE (AP) - Triple Crown contender Christian Yelich and Milwaukee advanced to an NL Central tiebreaker against Chicago with its seventh straight win.
