As mentioned, the Rays, Twins and Astros have their divisions locked up in the AL, and in the NL the Mets and Brewers have done likewise. Here are the only races left, and they're really not much of races:
In the AL, the Royals blew a 9-1 lead in the middle of the 7th to lose 10-9 to Cleveland, a critical loss for them which knocked them 3 back with only 6 games left. It looks like the only suspense might be whether the Blue Jays or Angels host the wild card game. In the NL, all 3 of LA, San Diego and Arizona are in the playoffs with the division up for grabs.
