The Angels trail Texas by five games with only eight left to play for both teams, putting the Rangers' magic number at four. Boston's Wild Card lead has receded to 3 1/2 games over the Angels, who were a game behind the Rays in a three-way race heading into Tuesday night's doubleheader nightcap in New York.
Toronto will be in St. Petersburg engaging the Rays this weekend while the Red Sox, trying to pull themselves out of a September swoon, visit the Bronx to battle the Yankees.
Boston finishes the season with three games at Baltimore while Tampa Bay will entertain the Yankees in its final series.
The Angels have gone 19-11 since Mark Trumbo's walk-off homer against Texas' Mike Adams on April 18. They finish at home, where they are 44-31, with three against the A's and three against the Rangers.
Even if Texas clinches the division and the Angels are still in the Wild Card hunt by the time they meet on Monday night, the Rangers figure to be motivated. They're running neck-and-neck with Detroit for home-field advantage in the best-of-five AL Division Series, the Yankees having virtually wrapped up one of the spots.
