2. Ricardo Lopez
RECORD: 51-0-1 (38 KOs)
COMPLEX SAYS: Lopez held titles in both the strawweight and light flyweight divisions. El Finito also defended his WBC Strawweight title a record 21 times from 1990 to 1999. He's only the third champion in boxing history to retire undefeated. Did we mention that homie fought his entire career between 105 and 108 pounds? Get your weight up, son! Nah, FOH.
