Thanks to a Cardinals victory, the Dodgers need to win out and hope St. Louis loses both its last two games to the Reds. One more loss or St. Louis win means the Dodgers' chances of sneaking into the postseason are officially over.
If the unlikely scenario plays out in the Dodgers' favor, Los Angeles would host a tiebreaker at home Thursday. However, that remains a big if at this point.
In the meantime, the Dodgers have shown they aren't going to just roll over without putting pressure on the Cardinals.
"We're still in this," catcher A.J. Ellis said. "[The Cardinals] are playing a strong team that is still fighting for home-field advantage in the playoffs and a bitter rival at that. It's definitely not over. The Reds have a lot to play for and so do the Cardinals. We are out here watching and hoping to take advantage of it."

A tiebreaker game will be played to determine a division winner, even if the tied clubs are assured of participating in the postseason. If a division championship tiebreaker is necessary, the head-to-head record between the clubs will determine home-field advantage. If the head-to-head record is tied, then the division record will be the next tiebreaker.
If two clubs are tied for the two Wild Card berths, home-field advantage will be determined by the head-to-head record between the clubs. If the head-to-head record is tied, then the division record will be the next tiebreaker.
