Floyd “Money” Mayweather remained unbeaten Saturday night when he was able to KO Victor Ortiz courtesy of a right hand late in the fourth round.

The shot came right after the two hugged in the middle of the ring after Ortiz delivered a head butt during the round. Mayweather was clearly irritated and as they separated Ortiz delivered the punch that sent Ortiz to the mat. Ortiz was then counted out as he struggled to get up.

In wild end to a fight that was dominated mostly by Mayweather who won his 42nd straight pro fight.
