Cristian Mijares may have ended the great career of former two-division world champion Rafael Marquez tonight, stopping his countryman in nine rounds in Mexico City.

Mijares (47-6-2, 22 KO) kept his winning streak alive, extending the run to 11 straight after three consecutive losses in 2008-09 put his own career somewhat in jeopardy. Marquez (41-8, 37 KO) kept the fight close on the scorecards, as the WBC's open scoring revealed after the fourth and eighth rounds, but Jake Donovan of BoxingScene.com says that "at no point did it appear that (Marquez) would permanently turn the tide in his favor."

Marquez, now 37, has been part of a brother tandem with Juan Manuel Marquez that I consider personally greater than the Klitschkos, and that's not meant as any shot at the Klitschko brothers, but rather that the Marquez boys have had to face greater, more skilled opponents over their careers, resulting in more losses for them, but far better fights, too. The time to go, though, may be here. It's not that he can't fight anymore, but his body seems to be telling him to hang up the gloves. He's had to postpone and cancel fights too often, and he's just not the same physically that he used to be. Better now than too late.

In the televised co-feature, Edgar Sosa escaped an upset bid from Myung Ho Lee, winning a majority decision on scores of 96-94, 96-94, and 95-95. Sosa is now 47-7 (28 KO), while Lee falls to 15-3 (5 KO).
