Leader Watch: NL Wild Card race tightens up

Two months ago, as play wrapped up on the evening of June 20, the three best teams by record in the National League could be found out west. The Rockies led the NL West by half a game over the Dodgers with a 47-26 record. The D-backs sat just 1 1/2 games back of the Dodgers, and the general assumption was that the NL Wild Card Game would be staged between whichever two of those clubs didn’t win the division.
