We could see a lot of waiver deals as teams thinking their in it on July 31st, find out they are not by the end of August.
Also, as of right now, 9 of the 15 AL teams ate 8.5 or more games behind the last WC slot. They'd have to pass 2 of these teams: NYY, SEA or OAK. I can see the TBR or LAA passing Oakland but not the other two. My guess is 9 AL teams already see themselves as out of it.
The NL is different. Only 4 teams are 10 or more games out of the WC slot. The other 11 are all within 5.5 games of the last slot. That may change by July 31st, but maybe not. There could be some more out by the end of August.
