LOS ANGELES (AP) -Abner Mares attacked relentlessly on the way to a unanimous decision over Anselmo Moreno on Saturday night, defending his WBC super bantamweight title and handing Moreno his first defeat in a decade.
Leo Santa Cruz also defended his IBF bantamweight title, stopping Victor Zaleta in the ninth round of a brutal fight on a thoroughly entertaining card at Staples Center.
Earlier, Welsh light heavyweight Nathan Cleverly defended his WBO title with an eighth-round stoppage of Shawn Hawk.
Mares (25-0-1) rarely stopped moving forward in a fascinating brawl with Moreno (33-2-1), the elusive Panamanian star. In the fifth round, Mares scored the first career knockdown of Moreno, who had won 27 straight fights since October 2002.
"I could tell he felt my power and my aggression," Mares said. "He did take advantage of me when I waited too long, but he's a super champion and he gave me hell. I couldn't let him get comfortable with his style, because he's very good. I made it my fight tonight."
Mares stalked Moreno from the opening bell, playing the bull to Moreno's matador in every corner of the ring. Moreno weathered the early rounds with his usual defensive flair and athleticism, but Mares is a nonstop puncher who usually corners his man - and he did it in the fifth round, staggering Moreno with a three-punch combination and then stepping back while Moreno fell to the canvas.
"I was a little shocked when he went down," Mares said. "I felt the punch, but didn't think it was that powerful."
Machismo took over the fight in the eighth round, with both boxers taking turns standing still and daring the other to throw his best shot. Mares' pursuit never stopped, however, sprinting after Moreno in the 12th round, with Moreno backpedaling at the same pace.
Judges Marty Denkin and David Sutherland scored the bout 116-110 for Mares, while James Jen Kin gave every round to Mares in a 120-106 whitewash.
"The fight should have been closer," said Moreno, who still holds a 118-pound title belt. "I'm unhappy that the one judge didn't give me at least one round, but Abner fought a great fight. He's a great champion. He was very strong, and I got caught by his shots. I was careless when I went down, but it was a great fight for the people. I'm happy for that."
Mares, who would love to fight Nonito Donaire next if their promoters can settle a deal, also showed his familiar lapses in punch discipline, hitting Moreno with a very low blow and a kidney punch. Mares didn't lose a point, but Moreno was docked in the 11th round for dangerously pulling down Mares' head in a clinch.
