Miguel Marriaga racked up his fifth straight knockout after stopping Alejandro Delgado after nine rounds in their featherweight bout Saturday evening in Mexico City. 

The action flowed back and forth early on, with Delgado making the visiting Colombian knockout artist work every step of the way in the first couple of rounds. Things changed dramatically in the third, when Marriaga floored the struggling journeyman with a left hook.

From there, a beating was delivered though Delgado remained determined to make a fight of it in front of his countrymen in attendance. Marriaga had too much to offer however, grinding him down until forcing the opposing corner to stop the fight upon the conclusion of the ninth round.

The nine rounds marked the deepest Marriaga has ever been forced to go in a prize fight. Still, the rising prospect came up aces with his most impressive performance to date, advancing to 12-0 (11KO). 

Delgado drops his fourth straight as he dips to 15-8 (7KO).

Patrick Texeira (17-0, 15KO) picked up his fifth straight 1st round knockout, drilling Alfredo Chavez just 13 seconds into their televised swing bout. A left hook seconds barely five seconds into the contest floored Chavez, who never made it up from the canvas as the referee stopped his mandatory count midway through to wave off the fight.

In the televised opener, Ulises Lara scored a major upset in stopping Jorge Amadaor in the fourth round of their scheduled six-round flyweight bout. Lara (10-12-2, 6KO) scored two knockdowns in the fourth, flooring Almador with left hooks and then battering his countryman until the referee intervened.

Lara had lost five straight heading into the fight, with his last win coming in March '11. Amador suffers his second straight loss as he falls to 6-5 (1KO).

All three bouts aired live on Cadenas Tres and also streamed live on www.wbcboxing.tv.
