PHOENIX -- Should the regular season end in a tie for the National League West, the Dodgers would host the D-backs for a one-game playoff on Monday, Sept. 29.

Major League Baseball did its annual coin flip to determine the site of a possible tiebreaking game, and Los Angeles won the toss. Los Angeles would host Arizona for a 163rd game at Dodger Stadium to determine the NL West champion.

Last season, the Padres and Rockies played a 163rd game at Coors Field in Denver -- a one-game playoff for a Wild Card berth -- with the Rockies victorious in a 9-8, 13-inning game that was the start of an eventual World Series run for Colorado.

The D-backs currently trail the Dodgers by 3 1/2 games in the NL West standings with 17 games left in the season for Arizona, and 16 for Los Angeles.
