If the standings hold true, the Phillies would host the Rockies in a rematch of the 2007 NLDS, when the Rockies swept the Phillies in the best-of-five series on their way to the World Series.
The Phillies, who are 4-2 against the Rockies this season, have the second-best record in the league behind the Dodgers. The Cardinals are two games behind the Phillies in the loss column. If the Phillies finish first or second in the league, they would have home-field advantage and play the Rockies in the first round because the Dodgers and Rockies, who both play in the NL West, cannot face each other in the first round.
Because the Dodgers and Rockies cannot meet in the NLDS, if the Phillies finish third behind the Dodgers and Cardinals, they would play the Dodgers in the NLDS. The Cardinals would play the Rockies. The Phillies are 3-4 against the Dodgers this season.
Regardless of what happens in the season's final days, they cannot play the Cardinals in the first round. The only could meet them in the NL Championship Series. The Phillies are 4-1 against the Cardinals this season.
