NEW YORK — Paulie Malignaggi won a unanimous decision against Zab Judah in a welterweight bout Saturday between two Brooklyn-born fighters billed the “Battle of Brooklyn.” The judges scored it 116-111, 117-110 and 117-110 in favor of Malignaggi (33-5) in a fight that had many in the crowd at Brooklyn's Barclays Center booing the lack of action. The 33-year-old Malignaggi landed 230 of his 607 punches thrown, including 122 of 376 jabs. He spent most of the fight with blood on the left side of his face. “It definitely allows me to continue boxing,” Malignaggi said. “With a loss, I don't know if I wanted to continue.” It was the third loss in four fights for the 36-year-old Judah (42-9), who is a five-time champion in the light welterweight and welterweight divisions. Judah landed 121 of 498 punches, including 67 of 386 jabs. “I was very motivated for this fight,” Judah said. “I came to fight and so did Paulie. He did a good job of staying outside. It just wasn't there.” All three fights on the undercard also went the distance. Shawn Porter (23-0-1) remained unbeaten and took the IBF welterweight title by outpointing Devon Alexander (25-2), 115-113, 116-112 and 116-112. Erlslandy Lara (19-1-2) retained his WBA Interim Super Welterweight championship with a unanimous decision over Austin Trout (26-2), who dropped his second straight fight since retaining the light welterweight title by defeating Miguel Cotto last December at Madison Square Garden. Sakio Bika (32-5-3) retained his WBC Super Middleweight championship by taking a split decision against Anthony Dirrell. Rigondeaux outpoints Agbeko In Atlantic City, Cuban dynamo Guillermo Rigondeaux retained his World Boxing Association super bantamweight title with a unanimous decision over Joseph Agbeko Saturday. Rigondeaux scored a dominating win over the challenger as all three judges at the Boardwalk Hall scored the fight 120-108 in his favor. “Every time I fight I try to improve but he was a tough rival,” said Rigondeaux, who is now 13-0 with eight knockouts. Former two-time champ Agbeko (29-5) has lost three of his last four fights. It marked Rigondeaux's first fight since his dominating victory earlier this year over Nonito Donaire. Asked after the fight if he would welcome a rematch with Donaire, Rigondeaux said he looks forward to it. Sturm regains world title In Berlin, Germany's Felix Sturm has become a world champion for the fourth time after winning back the IBF middleweight belt by dethroning England's Darren Barker with a second-round technical knock-out. Having lost the belt in September 2012 to Australia's Daniel Geale, who subsequently lost on a split decision to Barker in August, the 34-year-old Sturm regained his crown by putting the Englishman down twice in the second round. Barker beat the count twice, but with Sturm poised to finish him off, the Englishman's coach Tony Sims threw in the towel at 2:09 mins of the second round as Barker lost in the first defense of his world title. — Agencies
