The outcomes of these next three games would determine home-field advantage for a play-in game should the Cardinals and Dodgers end up tied for the second Wild Card. The Dodgers trailed the Cardinals by two games for that playoff berth entering Friday's game.
A tiebreaker game would be played on Oct. 4, the day after the regular season, at the home park of whichever team won more games in the head-to-head series. Through Thursday, the Dodgers and Cardinals had split their eight head-to-head games. Los Angeles won the first four, including a three-game sweep of the Cardinals at Dodger Stadium back in May. St. Louis has taken four straight since then.
The Cardinals have already lost season series against the Pirates (7-8) and the Phillies (2-5) should either of those clubs finish in a tie with St. Louis for the second Wild Card. A tie with the Brewers would result in a home play-in game for St. Louis, which won nine of the 15 head-to-head games against Milwaukee this season.
