# Mauricio Aceves

Mauricio Aceves (born 18 December 1960) is a Mexican former professional boxer in the Light welterweight division. He was the first ever WBO Lightweight Champion.

## Professional career

Mauricio has fought many undefeated boxers, including Shane Mosley, Dingaan Thobela, Todd Foster, Dennis Holbæk Pedersen, Billy Schwer and Rene Arredondo.

### WBO Lightweight Championship

Aceves won the WBO Lightweight Championship by upsetting the veteran Amancio Castro in Santa Ana, California.
