Lucas Matthysse stopped Mike Dallas Jr in the first round to retain his WBC interim super-lightweight title in Las Vegas on Saturday night. The Argentinian launched a devastating straight right hand to end the fight after only 2 minutes 36 seconds. Neither fighter had done much damage when Matthysse slipped a punch and landed a short right that sent Dallas face-first into the canvas at the Hard Rock Hotel.

"I was so relaxed. I was waiting for my opportunity to land a shot," Matthysse said. "I was waiting for him to throw his left, then he ducked and I connected with the right."

Matthysse improved his professional record to 33-2, including his 31st knockout. The result probably put Matthysse in position for a shot at WBC and WBA super-lightweight titles held by Danny Garcia or Marcos Maidana.

"I want Danny Garcia and all the top fighters at 140 pounds," Matthysse said. "I hope he doesn't avoid me."

The undefeated Garcia will face former champion Zab Judah on February 9. One of Matthysse’s two losses was when he was beaten on a split decision by Judah.

"Zab Judah has a great chance to win. This is boxing and anything can happen," Matthysse said.
