Marco Antonio Barrera retained his WBC super featherweight title in Las Vegas with a unanimous decision over American challenger Rocky Juarez.
Barrera finds Juarez with a left in Vegas
Judges awarded Barrera the victory by 117-111, 115-113 and 115-113 in a rematch of a May bout in LA that ended in a controversial Barrera triumph.
"I moved very fast, I used my jab. I knew if I had to take him to the school I would do it," said the Mexican.
Barrera improved his record to 63-4 while Juarez fell to 25-3.
In May, the first fight was initially announced to the crowd as a draw.
But minutes later Barrera was awarded a 12-round majority decision when two judges scored it for him by 115-114 and 115-113. The other saw Juarez as a 115-114 winner.
"I learned never fight to the level to the challenger," Barrera said. "I'm the champion. I need to use my experience."
Barrera controlled the tempo in Las Vegas with a conservative style, swelling Juarez's right eye in the fifth round.
"He caught me with a good uppercut and closed my eye," Juarez said.
"He fought a good fight. He kept a good jab. He kept retreating. I wasn't able to get a very good shot at him. When I got inside he wouldn't trade with me.
"He just smothered me and waited for the referee to break him up."
Juarez was off-balance much of the night in the tactical duel, Barrera guarding and moving well but neither man throwing combinations.
Filipino fighter Manny Pacquiao is the rival Barrera wants next. Pacquaio became the first man to stop Barrera in 2003.
