San Antonio, TX (SportsNetwork.com) - Hard-hitting Argentine Marcos Maidana floored Adrien Broner twice and took the WBA welterweight title with a 12- round unanimous decision at the Alamodome Saturday night.
The scores were 117-109, 116-109 and 115-110 as Maidana took the title Broner held since his win over Paulie Malignaggi in June.
Maidana (35-3, 31 KOs) sent Broner (27-1, 22 KOs) to the canvas for the first time in his career only 20 seconds into round two with a devastating left hook.
Despite being backed against the ropes and into corners consistently in the second, Broner spoke to referee Laurence Cole throughout the round.
Midway through round eight, Broner was victimized by another left hook, but Maidana gave the point right back when he was penalized for delivering a headbutt to the chin of his opponent. Broner went to the floor in obvious pain and the bout was stopped for a moment with 64 seconds left in the round.
Maidana acknowledged being hurt by a punch that came at the final bell of round 11, but finished the fight in dominating fashion and landed more than 100 more power punches than his opponent.
Fans threw debris at Broner as his camp raced to the tunnel before there could be a postfight interview. Broner was assisted to his dressing room, while Maidana was crowned champion and flashed the belt in delivering the first loss of Broner's career.
On the undercard, Beibut Shumenov kept his WBA super light heavyweight title with a third-round technical knockout of Tamas Kovacs.
Shumenov (14-1, 9 KOs) pounded Kovacs in the third round and delivered a right to the face while his opponent was in the corner. Referee Rafael Ramos stopped the fight with five seconds left in the round.
Kovacs (23-1, 14 KOs), a native of Slovakia, was fighting in the U.S. for the first time. It was a rude awakening for "Tomi Kid" as he was dropped in the first round with a left hook.
Leo Santa Cruz successfully defended his WBC super bantamweight title with a 12-round unanimous decision over Cesar Seda. Santa Cruz (26-0-1, 15 KOs) floored Seda (25-2, 17 KOs) in round five and went on to win by scores of 117-110, 116-111 and 115-112.
