Well to Riggs' credit, he got caught by a great punch when he threw a pretty good one of his own...he punched Diego right in the eye and if he didn't get KO'd Sanchez was in trouble.
Actually...you know what - Riggs should have kept his knee on the mat (not that it would have necessarily would have stopped Diego). If Diego hadn't landed that knee, he would have lost via that shot in the eye. I heard him say he couldn't see out of it at all, and he grabbed it immediatley after KO'ing Riggs.
Credit To Señor Sanchez though, he got that all-important W
on his record, and at the end of the day, that's really all that matters baby.
