Per Buster Olney’s Twitter this morning:
Elias (Sports Bureau): largest September deficit any team has overcome was 8 1/2 games,by the ’64 Cardinals. The Rays were nine games behind Boston Sept. 2.
There you have it. With 10 games left on the schedule, if the Red Sox manage to blow this 2-game Wild Card lead to Tampa Bay, it will be the worst choke in regular season history.
