Robert Guerrero began to make Floyd Mayweather work quite a bit in round nine of their bout but still was likely down by a considerable margin on the official scorecards.
Floyd landed some good left hands after he got off the ropes and out of a Guerrero smothering clinch attack that saw very little by way of actual punches that landed.
Mayweather started to work to the body, but did land almost a little bit below the belt.
Showtime showed their punch stat numbers that showed that Mayweather's power punches were landing at over 60%, an unreal number for championship level boxing, almost entirely based on his ability to work off the lead right hand.
Mayweather continued working the same jab, lead right, occasional left hook strategy to take yet another round.
Round: 10-9 Mayweather
Fight: 100-90 Mayweather
