NEW YORK -- Manager Joe Girardi admitted he would check in on the Orioles' score after the Yankees won Sunday, but after winning four of five and their final off-day of the season on Monday, the Yankees skipper also wants time to relax.

"I'm sure I'll check scores today, but that won't be the only score," he said of Baltimore's late game in Oakland, which the O's won, 9-5, as New York remained one game ahead of the O's in the American League East. "I'll check National League scores. I'll check what everybody's doing. I'll check the football scores, and I'm going to check the NASCAR race."

The Yankees extended their lead on Tampa Bay to five games after taking two of three at Yankee Stadium, ensuring they are in a good position for at least the second AL Wild Card spot. Oakland leads the Wild Card race, and the Yankees will welcome them to New York next weekend for three games -- their only remaining series against a playoff contender.

"I feel like it's one-day playoffs every day for us," said catcher Russell Martin.

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 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.
