Interesting take that with 9 to go, Sox might still not be eliminated from the WC chase. If starting pitching can make a next 30 game rebound as seen from Bello and Houck , and KC ever loses a game with Mariners treading water , this could happen.
But Criswell will need to rebound, Crawford needs to get into the 6th inning with some effectiveness and the BP , other than Martin/Jansen needs to find themselves.
I think it will come down to one team or another hitting a 9-10 Win streak or 9-10 game losing streak. If you look back at almost every opportunity Boston has had over the past 3 months to jump ahead, they have muddled around 2-3 wins/2-3 losses. Never a run of over 5 wins. Draw your own conclusions.
