Floyd Mayweather's Greatest Hits

Mayweather drew boos at catcalls with his perhaps unsportsmanlike (but definitely legal) knockout of the 24-year-old Ortiz to win the WBC welterweight title. After Ortiz was warned for head-butting Mayweather, they touched gloves, and Ortiz looked for referee Joe Cortez to signal a restart (Cortez said he did, but Ortiz said he didn't hear it) while Mayweather pounced on his unsuspecting opponent with a left-right combination in the fourth round.
