Though it had been reported that Justin Fortune, original co-trainer of Manny Pacquiao (second assist to Freddie Roach), was going to join Pacquiao's team once again, in fact, Sport Science Lab's Gavin MacMillan is Team Pacquiao’s newest member. With a fighter client list that includes UFC welterweight champ Georges St. Pierre, WBO junior welterweight champion Ruslan Provodnikov, Zou Shiming, Miguel Cotto and now, Pacquiao, MacMillan is becoming (if he isn't already) the go-to guy at the Wild Card Gym.

“I've been asked by Freddie to help as much as I can,” MacMillan told Maxboxing.com earlier this week before departing for the Philippines to join Roach and Pacquiao. “It is going to be a new experience for me. We only have a month but we are talking about, without a doubt, one of the best fighters that's ever existed. And so I think that he knows a lot about what his body needs. We just want to give him the right information to achieve what he needs in the ring and make sure that there are no injuries in camp at all. I am looking forward to seeing how he works up close and personal. I've been a longtime fan of his. He's somebody that is exciting to watch.”

MacMillan hopes to address the long-term problem Pacquiao has with his calves. The multi-division champion often complained about cramping up. “I think with Manny, it’s just making sure that his legs feel good. In the past, he has dealt with calf cramps and things like that, to be honest, are really simple to solve,” said MacMillan. “So it's just matter of making sure you have the right minerals in you and making sure that stretching is done properly. I've had a lot of success fixing that, so I am not worried about it.”

MacMillan is a clean sport advocate and with Provodnikov, St. Pierre and Pacquiao, he has three athletes all currently being tested by the Voluntary Anti-Doping Association (VADA). In Provodnikov's case, his testing just ended with the Mike Alvarado fight but likely, his next fight will include testing. It's a rare distinction in the sport.
