At the scheduled end of the regular season, the NL Central and NL West divisions each had two teams tied for the division lead; Cubs and Brewers in the Central, and Dodgers and Rockies in the West. This resulted in two tiebreaker games being played on October 1 to determine division winners, with the losers of the tiebreaker games—the Rockies and Cubs—relegated to this Wild Card Game.[2]
This was the first Wild Card Game to require tiebreakers to determine both teams,[3] and the first NL Wild Card Game to require any tiebreaker game, as the only other Wild Card Game to require a tiebreaker was the 2013 AL Wild Card Game. The Cubs and Rockies became the first teams in MLB history to lose tiebreaker games at the end of the regular season yet still enter postseason play,[3] as they played in the first divisional tie-breaker games needed since MLB's addition of a second Wild Card team in 2012.
The Cubs entered the Wild Card Game with a record of 95–68, while the Rockies entered at 91–72. The Cubs and Rockies tied the six-game regular season series 3–3, with each team winning two of the three games in its opponent's ballpark.[4] This was the first postseason meeting between the two teams.
