At this point in the Wild Card races, the teams on the outside looking in have gone into full-out survival mode.
And that's exactly what the Brewers, Dodgers and Angels all did on Sunday -- survive.
On a day when St. Louis and Oakland both won, the Brewers, Dodgers and Angels kept pace with crucial victories of their own.
The A's, who knocked off the Yankees, 5-4, in the Bronx to avoid what could have been a devastating sweep, lead the Angels by 2 1/2 games for the second Wild Card in the American League.
"It was a big game," Oakland manager Bob Melvin said of his club's win. "Each and every game will be big, but probably at this point in time of the year, that was our biggest win."
But the Angels responded to Oakland's early victory with an impressive performance of their own later in the afternoon. Jered Weaver tossed 6 1/3 innings of one-run ball to earn a career-high 19th win, as the Angels beat the White Sox, 4-1.
"Obviously there's a little bit of scoreboard watching as we dwindle down here, and [it's disappointing] that we don't get to play Oakland here at the end," Weaver said. "That'd be pretty exciting. But we have to do what we have to do, and that's win ballgames. We can't worry about what other teams are doing. We just have to go out there and keep winning. This is a good start."
Even though the White Sox lost, they still managed to extend their lead in the AL Central. That's because the Tigers dropped both games of their Sunday doubleheader against the Twins, including a 10-inning defeat in the nightcap as Minnesota's Jamey Carroll drove in the go-ahead run with an RBI single.
In the National League, St. Louis knocked off the Cubs, 6-3, to win the series against its arch-rivals. But the Cards didn't gain any ground as the Brewers (2 1/2 games back) beat Washington, 6-2, and the Dodgers (three back) beat Cincinnati, 5-3.
For the Dodgers, lefty Clayton Kershaw pitched for the first time since he saw a hip specialist in New York last week. He went five innings, allowing a run on five hits and five walks.

• 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.
