ONE: "Ascent to Power" is booked for the Singapore Indoor Stadium on May 6, 2016 and at the top of the card are two title fights. Vitaly Bigdash defends his Middleweight strap against Alexei Butorin in the headliner while the co-main event sees Angela Lee and Mei Yamaguchi go head to head for the inaugural women's Atomweight belt.
Bigdash (8-0) hails from Russia and beat previous champion Igor Svirid by second round stoppage due to strikes on his promotional debut last October. He's got four submission wins and four TKO wins on his record but has never been to a decision.
