Have you looked at their schedule?
1 more game @ Chicago WS [10-21]
3 games @ cleveland [14-16]
3 games vs San Diego [17-15]
3 games vs Chicago Cubs [15-15]
3 games @ La Dodgers [19-13]
3 games @ LA Angels [17-14]
3 games vs San Francisco [13-17]
3 games vs Toronto [18-13]
3 games @ Houston [16-15]
They could realistic lose every one of these series, going like 7-18 for the rest of this month.
If they're the best team in the division they have to win the games they should win and they haven't been doing that for the past couple weeks.
