Path to the Postseason: Sept. 14, 2012
Just when it seemed the Wild Card races couldn't get any wilder, Thursday's games offered a bit of clarity in both leagues, as the teams at the top put a bit of separation between themselves and their closest pursuers.

Thursday's action began with the Orioles sweeping the Rays with a dramatic 3-2 victory in 14 innings. Manny Machado's walk-off single -- just out of the reach of a sprawling Matt Joyce, whose Rays now sit four games back -- gave the Orioles a fleeting half-game lead over the Yankees for first place in the AL East, and secured their first season at .500 or better since 1997.

"There's a bigger goal in mind, and that wasn't the goal from Day 1 this spring," Orioles manager Buck Showalter said. "It's like watching other teams for years and saying, 'We want to do what they're doing. We'd like to get a chair at the dance.'"

Later in the afternoon in Anaheim, Jered Weaver pitched a gem after missing his last start because of right biceps tendinitis. The Angels' 6-0 victory moved them to 3 1/2 games out of the Wild Card and 4 1/2 behind Oakland, which currently holds the top Wild Card slot.

"Every game's important, man," Weaver said. "We're trying to go out there and win every game and see what happens."

The night games saw the National League take center stage, after the Yankees had wrapped up their 2-0 victory over the rival Red Sox. Phil Hughes tossed 7 1/3 shutout frames, as New York kept pace with Baltimore atop the AL East.

The red-hot Phillies had a four-run lead slip away in Houston and, as a result, their seven-game winning streak was snapped and their Wild Card deficit stretched to four games.

That's because in the lone late game, the Cardinals held on for a crucial 2-1 victory over Los Angeles. St. Louis -- now two games up on Los Angeles -- cemented itself as the team to catch for the National League's final playoff spot.

In Chicago, the Tigers-White Sox clash was washed away by rain and rescheduled for Monday. The South Siders hold a one-game edge heading into the weekend.

Magic numbers
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.

Tiebreaker scenarios
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.
