There were three more important results in the SMW division last night than this one IMO, and while it was, I suppose a fairly big domestic fight, it was not so big if you look at the division worldwide, which is currently not so well represented by American fighters at the moment.

Calzaghe beat Bika to remain the #1 SMW in the World.
Kessler unified WBC and WBA titles with a vicious 3rd round KO of fading German Markus Beyer.
WBO mandatory challenger Rudy MArkussen lost in a shock 7th round KO to journeyman Russian Sergey Tatevosyan

That's why not too many are speaking about Manfredo/Spina, which was unlikely to provide a shock, and went to the book.
