Pacquiao eyes comeback upset in Barrios showdown

Thirty years after clambering through the ropes for his first professional fight as a skinny 16-year-old, Manny Pacquiao returns to the ring once more on Saturday for the latest round of his protracted battle with Father Time.

The 46-year-old Filipino icon takes on World Boxing Council welterweight champion Mario Barrios at the MGM Grand Garden Arena in Las Vegas chasing another milestone to crown his glittering 30-year professional career.

Pacquiao stunned the boxing world in May when he announced that he planned to end his four-year exile from the sport to challenge Barrios, taking advantage of a WBC rule that allows former champions to request an immediate title fight when coming out of retirement.

Pacquiao, who is reportedly set to receive between $5-10 million for Saturday's fight, says his comeback is motivated by his passion for the sport and the adrenaline rush of headlining a Sin City fight night.

"I'm returning because I miss my boxing,” Pacquiao said during a recent publicity tour.
