In the unlikely event the Rangers were to lose all their remaining games and the Astros won out, they would play a one-game tiebreaker -- Game 163 -- to decide the winner of the division. The Rangers dominated the season series between these in-state rivals, 15-4, and would host a potential tiebreaker game.
While also unlikely, if the Rangers were to lose all their remaining games and the Mariners won out, they would finish tied for the division. With a 12-7 record against Seattle this season, Texas would host a potential tiebreaker game. The Astros and Mariners play each other Sept. 26-28, so they couldn't both tie the Rangers.
Up next for Texas is a three-game series in Oakland. The Rangers then return to Arlington for their final six-game homestand against the Brewers and Rays.
