Ring rust and old age were supposed to be two of the factors that Floyd Mayweather would face when he stepped into the ring with Robert Guerrero.
Neither of those factors were on display as Mayweather (44-0) pounded out a unanimous decision over Guerrero (31-2-1).
Mayweather dominated the fight with his sharp, accurate punching. Guerrero was very aggressive throughout, coming after Mayweather and looking for his openings, but he could not find them.
Mayweather may not have been in the ring for a full year, but he found his timing after the second round and put on one of his sharpest performances in recent memory.
Here's a look at Mayweather's grades for his performance against Guerrero.
