Two updates.
First, let's look at the 7 games against the Cubs and the resulting magic numbers. Each team has 18 other games, so let's see what the Cubs would need to do to win the Central if the Brewers went 9-9.
Brewers win:
0: magic number is 18, Cubs would need to go 10-8 if Brewers went 9-9.
1: 16, 12-6
2: 14, 14-4
3: (3 wins guarantees the Brewers win the tiebreaker) 11, 17-1
4: 9, no scenario for Cubs if Brewers go 9-9; if Brewers go 8-10, Cubs need 18-0
5: 7, Brewers need to go 6-12 and Cubs go 18-0
6: 5, not worth talking about
7: 3, ditto
So, really, just don't get swept. 3 or more wins puts it away pretty safely. Still need to watch the Dodgers and Braves, though,..
Second, here's an update on where the Brewers stand on their magic number vs. other teams:
ATL: 23
LAD: 22
PHI: 18 (currently tied with CHC for top WC)
SD: 13
AZ: 12 (Note: AZ is currently the #3 wild card with a half game lead over SD, but MKE has tiebreaker on AZ, and not on SD)
MIA: 9
STL: 7
PIT: 7
CIN: 5
WAS: 4
NYM: 1
SF & COL: clinched
