The contingency plans are set. Major League Baseball has set up start times for potential Wild Card tiebreakers in both leagues as the regular season comes to an end. Either or both of those games would be played Thursday, the day before the American League playoffs start.

If the Red Sox and Rays finish in a tie for the American League Wild Card, a play-in game would be set for Thursday at 4:07 p.m. ET at Tropicana Field. The Rays went 12-6 against Boston in the regular-season series to earn home-field advantage for the tiebreaker.

If Atlanta and St. Louis finish the season in a tie for the National League Wild Card, a tiebreaker would be set for Thursday night at 8:07 ET at Busch Stadium. This game would be scheduled for that time even if the AL doesn't have a play-in game.

The AL Division Series will begin Friday, and start times are set for 5:07 p.m. ET and 8:37 p.m., respectively. The first game will feature Boston or Tampa Bay at Texas or Detroit, and the second game will be the Rangers or Tigers on the road against the Yankees.
