Mayweather vs. Guerrero results live: Round 1

USA TODAY Sports

A breakdown of the action from the first round of Floyd Mayweather vs. Robert Guerrero on Showtime pay-per-view.

Floyd Mayweather and Robert Guerrero got their Showtime pay-per-view bout underway following the usual big fight pageantry of national anthems and dramatic ring walks. During the referee's instructions Ruben Guerrero and Floyd Mayweather Sr. began jawing at each other while their sons engaged in a very intense staredown.

Mayweather came out and stood flat, landing right hands and ducking under Guerrero's punches. Mayweather landed a good amount of straight right hands but Guerrero clinched and really tried to rough Floyd up in the clinch, drawing early warnings from the referee.

Guerrero bulled forward and landed a decent shot but Mayweather went back to landing the jab and trying to moves out of range, popping off with more straight right hands. Guerrero appears content to try to counter the right hand of Mayweather and has almost found success, something that might be very big as the fight wears on.

Round: 10-9 Mayweather
