She began her career in professional boxing at the age of twenty-six, when she and Andrea Buchanan drew (tied) after five rounds on November 1, 1989, at Bristol, Tennessee.
Riccio Major obtained her first victory, a five-round decision win over Stacey Prestage, on her second bout, held on November 17, 1990, in Fort Myers, Florida.
For her third bout, held on February 25, 1991, also at Bristol, she met young rising star Christy Martin, who dealt Riccio her first loss, beating her by a five-round decision.
On January 17, 1997, Riccio-Major earned her first, and only, professional boxing knockout win, when she defeated Patricia Simms in the first round, at Waukegan, Illinois.
She suffered, however, a three fight losing streak after those three wins, being defeated by "Downtown Leona Brown" on points, by Trevino in a rematch which saw both women go down, by Tko in five rounds, when referee, the late Mitch Halpern stepped in for no apparent reason.
