Diaz out-points Penn
Penn took the opening round of the fight as he started fast, as he usually does. Penn used his grappling to better Diaz, but Diaz responded by winning the next two rounds with dominant boxing. He busted up and bruised Penn for the final 10 minutes to clearly earn a unanimous decision on the scorecards of all three judges.
According to oddsmakers, Diaz was a slight underdog in the bout with a money line of -105. That means a $105 wager on Diaz will pay out an additional $100.

Kongo had a money line of +110 to win, meaning a $100 wager on Kongo will pay out an additional $110.
