Mayfield stops Serrano to retain title

Karim Mayfield staggered Raymond Serrano at the fourth-round bell, and then landed a solid right hand less than a minute into the fifth that stopped the challenger in the NABO junior welterweight title fight Friday night.

Mayfield and Serrano both swung at the bell of the fourth round, but Mayfield’s punch landed, wobbling Serrano (18-1).

Mayfield (16-0-2 10 KOs) came out with a flurry in the fifth, and referee Eddie Claudio stopped it with Serrano wobbling 47 seconds in.

Mayfield, listed shorter by an inch and crouching to make himself shorter, effectively ducked under many of Serrano’s punches in the first three rounds. Mayfield sent Serrano down in the third with a right counter and two more punches.
