Pacquiao throws bombs at heavy bag on Day 2 of training camp at Wild Card Gym

Eight-division champion Manny Pacquiao is already showing glimpses of his vintage form as early as day two of his training camp at the famed Wild Card Boxing Gym in Los Angeles, USA.

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

Pacman spent the early days of his training camp under the watchful eye of his longtime friend and trainer Buboy Fernandez in General Santos.

Team Pacquiao left the Philippines this past weekend and on his first day of training jogged at the Pan Pacific Park before heading to the gym.

Pacquiao, who conceded that Spence could be the toughest fight of his career, however impressed his Hall of Fame trainer Freddie Roach in his first visit to the Wild Card in two years.

"If this is how Manny hits with jet lag, I may need to get new gloves with thicker padding for our next sessions," said Roach after their day one of their training camp.

"He was incredibly sharp for his first day. He hit hard with good power."
