The White Sox now sit three games ahead of Detroit, a position that allows them to focus solely on themselves -- no scoreboard watching necessary -- going forward.
"Be sure you worry about yourself and not worry about anything else," manager Robin Ventura said. "There's nothing you can do about [the Tigers]."
The Phillies pulled to within 3 1/2 games in the NL Wild Card, thanks to a gem from Cliff Lee, who outdueled the Mets' Cy Young candidate, R.A. Dickey.
"We've got three or four teams ahead of us that we've got to catch and pass," Lee said after he allowed one run and struck out 10 in eight innings. "It's definitely not where we want to be, but we've still got a chance. Considering how we played the first half, we're pretty lucky to be where we are right now, to be honest with you."
In other games of note, the Braves beat the Marlins to further tighten their grip on the top NL Wild Card spot, and the Rays dropped to five back in the AL Wild Card race with their 5-2 loss to Boston.
Tampa Bay's deficit reached five when the Orioles thumped the Mariners, 10-4, in Seattle. Nate McLouth and Matt Wieters each homered to pull them within half a game of the Yankees in the AL East.
Strangely, it was the Pirates and Cubs finishing the night up in Chicago, thanks to a rain delay that lasted three hours and 37 minutes. Kevin Correia threw seven two-hit frames to pull the Bucs to within 2 1/2 games of St. Louis in the Wild Card race.

Blue Jays (Romero, 8-14) at Yankees (Pettitte, 3-3), 7:05 p.m. Preview >
Andy Pettitte makes his return in the Bronx as the Yankees look to expand their lead in the AL East. A healthy Pettitte would be a vital piece in a rotation that needs depth.

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 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 division record will be the next tiebreaker.
