Perez counted out at 1:53

Juan "The Hispanic Causin' Panic" Lazcano (34-3-1, 26 KOs) made good in his first start after failing to win the WBC lightweight title against Jose Luis Castillo last September, stopping Culiacan, Mexico's Marco Angel Perez (21-8, 14 KOs), in the first round of a scheduled 10-round bout Friday at the Don Haskins Center in El Paso, Texas.

Perez came out aggressively, landing a few shots that seemed to wobble Lazcano in the opening seconds of the bout. But moments later, as Lazcano held Perez's right arm, the local hero delivered a wicked right-hand uppercut on the inside that sent Perez crashing down to the canvas.

Perez was not able to rise, and he was counted out at 1:53 of the first stanza.

This is the second consecutive first-round loss for Perez, who was also brutally knocked out by former IBF lightweight champion Julio Diaz with an uppercut in the first round of their fight in June.

"Chente" stops Matias in one
In the co-feature, 2004 U.S. Olympian Vicente "Chente" Escobedo kept his perfect record (6-0, 6 KOs) intact by stopping Juan Manuel Matias (8-3, 3 KOs) at the end of the first round.

After tasting the first solid right hand from Escobedo, Matias went strictly into counterpunching mode as the hard-punching lightweight pressed forward, landing the better shots to win the first round easily.

Escobedo, having established a jarring jab, let his shots flow once more as Matias remained on the defensive, trying to keep his aggressive foe off with shots of his own, something that did not work as "Chente" landed a clean left hook to Matias' jaw that sent him down on the seat of his pants with just seconds to go in the round.

Matias failed to answer referee Wilfredo Esperon satisfactorily after making it to his feet, and the bout was halted at 2:58 of the first round.

Escobedo's next outing will take place on the Sept. 17 Marco Antonio Barrera vs. Robbie Peden undercard.

Escalante scores four knockdowns
On the undercard, super bantamweight Antonio Escalante (8-1-0, 6 KOs) from nearby Juarez, Mexico, dropped Terrance "Anger Management" Roy (8-14, 1 KO) four times en route to a second-round TKO.

Roy was down from a three-punch Escalante combo at the two-minute mark in the first round, and Escalante scored two more knockdowns before the round ended.

Escalante did not let up, concentrating on ripping body shots that doubled up Roy, sending him to the canvas a fourth time to prompt the immediate stoppage at 1:43 of the second round.

Soto decisions Torres
Super lightweight Orlando Soto (7-11-1, 2 KOs) defeated Saul Torres (6-2-0, 4 KOs) via a six-round split decision.

After a sluggish start, Soto slowed the speedy Torres with a heavy, methodical attack that featured deceptive speed in beating Torres to the punch through six rounds of action in which Soto gained the upper hand as the rounds went by.

Scores were 58-56 (twice) for Soto and 58-57 for Torres, giving the split decision win to Soto, who is the younger brother of former WBC Featherweight champion Cesar "La Cobrita" Soto.
