The Tampa Bay Rays and Texas Rangers are pushing this regular season to game No. 163.
On a Sunday, Tampa Bay and Texas both won and wound up even, forcing a tiebreaker for the second AL wild-card spot.
The Rays will play at Texas on Monday night, with the winner visiting Cleveland on Wednesday night in another all-or-nothing matchup.
Rangers rookie Martin Perez starts against reigning AL Cy Young winner David Price. Texas gets a boost, too All-Star slugger Nelson Cruz will be active after his 50-game penalty from Major League Baseball in the Biogenesis drug scandal.
It will be baseball's first tiebreaker officially, this is a regular-season game and the stats count since Minnesota beat Detroit 6-5 in 12 innings for the 2009 AL Central title.
What was supposed to be the final day of the regular season began with the possibility of a three-way tie for a pair of AL wild-card spots. Instead, Cleveland clinched its first postseason berth since 2007, winning 5-1 at Minnesota to finish at 92-70 and one game ahead of Texas and Tampa Bay as the top wild card.
