CINCINNATI -- In what management felt was a game crucial enough to start the ailing Clayton Kershaw, the Dodgers held on Sunday to beat the Reds, 5-3, and keep pace with St. Louis and Milwaukee for the second National League Wild Card berth.

St. Louis still leads the Dodgers by three games and Milwaukee by 2 1/2 games. The Dodgers have nine games to play, beginning Tuesday night with a three-game series in San Diego. The Dodgers are off Monday.

For the Padres series, the Dodgers expect to have Hanley Ramirez in the starting lineup. Ramirez left Sunday night's game in the seventh inning after fouling a pitch off his left shin, but X-rays were negative.

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.
