Boxer Terence Crawford dominated Saul "Canelo" Alvarez in a fight in Las Vegas and became the first in the modern era to unify titles in three different weight classes.
In front of 70 spectators, most of them Alvarez supporters, Crawford offered a boxing masterpiece, despite coming up two divisions higher.
The 37-year-old boxing star showed off his arsenal of strikes, defense, power and timing, leaving the 35-year-old Alvarez powerless and silencing the initially noisy crowd.
Crawford won on points, but the judges' scores surprised most boxing fans. The American's victory was considered more convincing than the official score, 116:112, 115:113 and 115:113.
"I'm not here by accident," said Crawford, who won the WBA Super, WBC, WBO and IBF super middleweight titles.
Crawford knelt down after being declared the winner. He was very emotional. He has 42 wins, 31 of them by stoppage. He has not experienced draws or losses. The American has left the possibility of retirement open.
"I don't know, I'll sit down with the team and talk about it," Crawford added.
On Mexican Independence Day weekend, Alvarez had the burden of boxing for the status, pride and hopes of a country. But he faced a legend of a generation. Alvarez suffered his third loss in 68 fights in his career.
"It feels good to share the ring with the greatest boxers like him. If we do it again, it would be great," Alvarez said. "My legacy is already built. I like to take risks because I love boxing," said Mexican Alvarez, who has 39 of his 63 wins by stoppage.
Alvarez boxed for the 21st time in Las Vegas, the city that made him a stronghold for two decades. But this time he was up against the best.
Legends like Mike Tyson and Evander Holyfield were close to the ring. The fight is considered one of the greatest of recent years.
Crawford was the undisputed champion in both the super lightweight and welterweight divisions. He also held world championship titles in two other professional boxing divisions.
