PHILADELPHIA -- As they head toward the finish line, the Phillies' chances for a sixth consecutive postseason berth are very slim.
After their 8-2 loss to the Braves on Saturday, they trail the St. Louis Cardinals by four games for the National League's second Wild Card. The Milwaukee Brewers remain 1 1/2 games ahead of the Phillies, and the Los Angeles Dodgers lead them by a game.
If Philadelphia was to win each of its final 10 games, St. Louis would need to go only 6-4 to tie. The Phillies play the Braves one more time, the Nationals six times and the Marlins three times.

This is how the teams would match up: Postseason Bracket »
To calculate a team's magic number, take the number of games it has remaining and add one. Then subtract the difference in the number of losses between that team and its closest pursuer.
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.
