(AP)--The St. Louis Cardinals are tied with Atlanta for the NL wild-card lead, getting a clutch two-run triple from Ryan Theriot in the seventh inning of a 13-6 victory over the Houston Astros on Tuesday night.
The sliding Braves lost 7-1 to Philadelphia, sending the race for the NL's final playoff spot to the final day of the regular season.
If the teams are tied after Wednesday's game, St. Louis will host a one-game playoff on Thursday night.
The Cardinals trailed 5-0 early and appeared to be headed for a second straight loss to the Astros.
But St. Louis scored five times in the fourth and erased a 6-5 deficit with a four-run seventh.
Lance Berkman hit a two-out single and scored on Allen Craig's tying double.
Yadier Molina walked before Theriot's triple made it 8-6.
