CHICAGO -- The Rays defeated the White Sox, 6-2, on Sunday afternoon to keep their playoff hopes alive even though they were eliminated from the American League East race.
The division-leading Yankees defeated the Blue Jays on Sunday to eliminate the Rays.
But the Rays remained three games back of the Athletics, who beat the Mariners, 5-2, for the second spot in the AL Wild Card race. With three games left, Tampa Bay, which has an elimination number of one, will need help to get into the postseason.
Tampa Bay is also tied with the Angels, who split their day-night doubleheader with the Rangers.
The Rays have won 10 of their past 11 games.
"It's always about maintaining a slight mathematical chance," Rays manager Joe Maddon said. "We were in the same boat last year. ... We just have to go home and play our game. I still believe we can do this. But regardless, you have to appreciate our guys. That's 10 out of 11 at this time of year, under these circumstances where we can't have a hiccup."

A tiebreaker game will be played to determine a division winner, even if the tied clubs are assured of participating in the postseason. If a division championship tiebreaker is necessary, the head-to-head record between the clubs will determine home-field advantage. If the head-to-head record is tied, then the division record will be the next tiebreaker.
If two clubs are tied for the two Wild Card berths, home-field advantage will be determined by the head-to-head record between the clubs. If the head-to-head record is tied, then the division record will be the next tiebreaker.
