Mitch Williams on MLB Tonight talks about how he knew that David Robertson wasn't going to be able to close because of his interview after the Rivera injury because of how he said "He will do his best, but he is no Rivera". Then takes a jab at how 'sabermetric people' say anyone can close, but this is proof that no, they can't.
Mitch Williams probably considers himself a closer. Mitch Williams blew his 2nd save chance, his 4th save chance, his 5th save chance, 7th save chance and his 8th save chance of his career.
I guess he wasn't able to close either.
