It may make a difference or not but either way, condolences to the Mariano Rivera and his family, he lost two relatives, they died cleaning his pool.

We never want to hear things like that.
If Rivera does'nt play this series or misses some games, Yanks have no chance, but family comes first. I think he will play though.
