Pacquiao dazzles fans with hand speed on third day of training camp

Eight-division champion Manny Pacquiao wowed his adoring fans with his dreaded hand speed after a morning run at Griffith Park in Los Angeles, United States.

The 42-year-old Pacquiao is slated to challenge WBC and IBF world welterweight champion Errol Spence Jr. on August 21 at the T-Mobile Arena in Las Vegas.

Pacquiao spent the early days of his training camp in General Santos under the supervision of Buboy Fernadez, who flew with him to LA this weekend.

Oddsmakers see the Filipino boxing icon as a huge underdog against Spence and Pacquiao himself says that his next bout could be the toughest fight of his career.

"Errol Spence is a very difficult fight for me; perhaps the most difficult of my career, but I have been an underdog my whole life. I am used to that. It is why I work so hard," he said.
