But at the end, it was a dull 12-round-affair as neither Floyd Mayweather nor Manny Pacquiao came close to the knockout.
Mayweather came with a game plan and he succeeded, coming out of his biggest test, still undefeated,
It was however a game of cat and mouse, as Mayweather systematically and tactically dodged and countered while Pacquiao charged and missed often.
Many on social media compared Mayweather tactics to that of Chelsea manager Jose Mourinho who also tactically frustrates opponent with a defensive approach and pouncing on a counterattack.
Just as Mourinho is about to win Chelsea another English Premier League title, Mayweather will be remember as the man who won the 'Richest Fight in Boxing History' as at this time.
For 12 rounds of the game, Mayweather proved himself once again the grand master of the noble art of self defence.
He concentrated on getting his points and guarding himself from Pacquiao who was looking for a knockout blow on Mayweather.
Three judges in the end decided on the score and Mayweather with leading 118-110 and 116-112 twice, was declared winner of the night.
"I thought I won the fight. I hit him more times than he hit me. I hurt him more than he hurt me," Pacquiao protested.
It was mixed feelings for the 16,507 crowd in the MGM Grand Garden Arena, as some won bets while others lost.
