By The Numbers: Denice Zamboanga vs. Julie Mezabarba

Margin for error looks to be menacingly thin for Denice Zamboanga and the rest of the One Championship women’s atomweights.

The Filipino standout will seek to improve upon her 4-2 record within the company when she meets Julie Mezabarba in a featured ONE on Prime Video 9 attraction this Friday at Singapore Indoor Stadium in Kallang, Singapore. Zamboanga has lost two of her past three fights. She last appeared at ONE on Prime Video 5, where she eked out a split decision over Heqin Lin across three rounds on Dec. 2. Mezabarba, meanwhile, finds herself on a two-fight losing streak. She last competed on June 3, when she wound up on the wrong side of a split verdict against Jennifer Olsim at ONE 158.
