Chris Sale takes the mound for the White Sox on Saturday, with Matt Moore going for the Rays. Justin Verlander takes the baseball for the Tigers at Target Field, meaning both games are almost must-wins for the division contenders with their respective aces pitching.
But with just one game separating the two and a handful of games left on the 2012 regular-season ledger, all of these contests become must-wins.
"We're encouraged, we're pumped up," said White Sox starter Gavin Floyd, who got the win on Friday. "We're ready to go and will try to win tomorrow and see what happens."
"It's mentally exhausting. It's like we're playing in the playoffs right now and it's been like this for quite a bit," said White Sox right fielder Alex Rios, who delivered the game-winning homer in the fourth inning on Friday. "But you know what, it might be good because we're getting used to it. If we make it, and I think we're going to make it, it's going to help us because our minds are going to be in that mindset. It's going to be good."

This is how the teams would match up: Postseason Bracket »
To calculate a team's magic number, take the number of games it has remaining and add one. Then subtract the difference in the number of losses between that team and its closest pursuer.
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.
