Manny Pacquiao retained his WBA world welterweight title with a convincing unanimous points win over Adrian Broner in Las Vegas.
The Filipino, in his 70th fight and his first as a 40-year-old, rocked the former four-weight world champion with a stunning left in the ninth round.
He dominated his American opponent, who is 11 years his junior, connecting with more than twice as many punches.
Judges scored the bout 117-111, 116-112, 116-112 in Pacquiao's favour.
Afterwards, Pacquiao said he would be open to a rematch with unbeaten American Floyd Mayweather, who defeated him in 2015.
"Tell him to come back to the ring and we will fight," said Pacquiao, who is a senator in his homeland and fighting in the United States for the first time in two years.
"I am willing to fight with Floyd Mayweather if he is willing to come back to box."
Former five-weight world champion Mayweather, who was in the crowd, gave no reaction when asked if the rematch could happen.
The 41-year-old beat Japanese kickboxer Tenshin Nasukawa in an exhibition boxing bout in December but has previously said he is "still retired".
