Juan Manuel Márquez Méndez

Juan Manuel Márquez Méndez (born August 23, 1973) is a Mexican former professional boxer who competed from 1993 to 2014. He held multiple world championships in four weight classes, from featherweight to light welterweight, including the lineal championship at lightweight.

In a career that spanned over twenty years, Márquez was known for being a fast and highly technical boxer who was exceptionally skilled at combinations and counterpunches, yet also willing to engage in slugfests with opponents. He was also credited for his toughness, and never lost a fight by stoppage. His most notable bouts include his four-fight saga with Manny Pacquiao and his fight against fellow Mexican Marco Antonio Barrera.
