Marcos Maidana overpowered Adrien Broner to win the WBA welterweight title in San Antonio on Saturday night.
The Argentinian knocked Broner down twice before winning by unanimous decision 115-110, 116-109 and 117-109.
Broner, who suffered his first loss in 28 bouts, ran out of the ring after the scores were announced.
Broner is nicknamed The Problem, but Maidana, who improved his record to 35-3, had the answer: power that the three-time world champion had never faced before.
"I had to show a lot of heart to win this fight," Maidana said. "I did what I had to do to win. Broner is a very good puncher," Maidana said. "He's a very good boxer, very good puncher. Yes, I felt his blows."
