Born August 23, 1973 in Mexico City, Mexico.
Marquez turned pro in 1993 and captured the NABO, NABF and USBA featherweight titles before stopping Manuel Medina (TKO 7) for the vacant IBF featherweight title and Derrick Gainer (TW 7) for the WBA featherweight “super” belt in 2003. Before being stripped of both belts in 2005, he drew with Manny Pacquiao and scored 12-round wins over Orlando Salido and Victor Polor in title defenses. Following a controversial loss to Chris John (L 12) for the WBA belt, he rebounded to win the interim WBO title in 2006. Marquez moved up in weight to win the WBC super featherweight strap with a win over Marco Antonio Barrera (W 12) in 2007. He lost his belt to Pacquiao in a rematch (L 12) the next year. A win over Joel Casamayor (TKO 11) preceded a 9th round TKO over Juan Diaz to win the WBO lightweight and WBA “super” world lightweight belts in 2009 to become a three-division champion. After defending against Diaz (W 12) and Michael Katsidis (TKO 9), he unsuccessfully challenged Pacquiao (L 12) in their third bout for the WBO 147-pound belt. He defeated Serhiy Fedchenko (W 12) for the WBO light welterweight title to become a four-division champion. In 2012, he knocked out Pacquiao in the 6th round of their fourth meeting.
Following a loss to Timothy Bradley (L 12) and a win over Mike Alvarado (W 12), the gifted boxer / puncher retired in 2014 with a record of 56-7-1 (40 KOs).
