Other games update:
Philies beat the Brewers 4-2. Cubs move to 3.5 of Milwaukee and stay 2.5 behind Philly
Orioles up 2-1 on Arizona. Orioles win would increase the Cubs lead over Arizona to 3 games.
Padres up 3-0 on San Francisco. Padres win would increase the Cubs lead over the Giants to 3 games.
Marlins swept the Nationals with a 6-4 win, keeping them 3 games behind the Cubs
Reds of course lost and are 3 games behind the Cubs.
So if the scores hold the Cubs would have a 3 game lead over 4 different teams, with the 5 teams playing for 2 playoff spots.
Of those 4 other teams, the Cubs have lost the tiebreaker to 2 of them (Cincinnati and Miami), lead the tiebreaker 2-1 over the Giants (must take 2 of 3 to clinch it this week) and haven't played the Diamondbacks yet (must go 4-3 in the 7 games to win the tiebreaker)
