In the NL, the Braves (89-71) are trying to hold off the Cardinals (88-72).
Tie for the AL Wild Card? The Rays would host the tiebreaker game, by virtue of their 12-6 regular-season edge over the Red Sox.Tie for the NL Wild Card? St. Louis would be the host for the 163rd game, given its 5-1 regular-season edge over the Braves. Either, or both, would be played on Thursday, the day after the conclusion of the regular season. As for home-field advantage in the Division Series, regardless of whether the Red Sox or Rays win the Wild Card, the Yankees will face either the Tigers or Rangers -- whoever has the lesser record at season's end. The Rangers' record remains one game better, but should they finish knotted up, the Tigers hold the tiebreaker on the Rangers by virtue of their 6-3 season advantage. Detroit would face the Wild Card, and the Yanks would face Texas.
The Brewers hold a one-game edge over Arizona for the No. 2 seed in the NL. Should those two teams finish tied, the D-backs would get the higher seed by virtue of their 4-3 season-series victory. That would mean facing the Braves if they win the Wild Card, or the Brewers if the Cardinals overtake Atlanta for the final spot.
