After surviving two tours of duty with the Army in Iraq, Sammy Vasquez finds action inside the boxing ring relatively under control. Vasquez says he suffers from PTSD, but he has become a top contender for the world welterweight title with a record of 20-0 and 14 KOs. The next bout for the 29-year-old Pennsylvania native is Saturday at Staples Center on card to be televised on Fox. His opponent is Aron Martinez (20-4-1, 4 KOs). Thanks to City of Angels Boxing Gym, we had a chance to hear Vasquez tell his story about transitioning from soldier to boxer.
