Professional career
In 2000, Gainer defeated Freddie Norwood to win the WBA featherweight title and after four defenses lost to Juan Manuel Márquez, who became super champion, via technical decision in 2003. Since his defeat to Marquez, Gainer lost in a challenge to WBA titleholder Chris John via unanimous decision. Gainer is also a colleague and good friend of fellow Pensacola, Florida native Roy Jones Jr., and often fought on his under-cards.

His last was a split decision win over Carlos Navarro on the undercard of the Roy Jones-Anthony Hanshaw bout at the Mississippi Coast Coliseum, in Biloxi, Mississippi.
