“Unstoppable” Angela Lee overcame a spirited performance from Japanese MMA veteran Mei Yamaguchi to clinch the inaugural ONE women’s atomweight world title in Singapore last night.

Lee and Yamaguchi traded heavy blows and showcased high-level, tactical grappling skills all throughout the fight.

Yamaguchi started out strong, but Lee came on late and scored points for multiple near-finishes. Throughout five gruelling rounds, Lee dug deep in the second half of the bout, doing just enough to earn the unanimous decision victory.

In the evening’s co-main event, Roger Gracie dispatched previously-unbeaten opponent Michal Pasternak of Poland with ease, securing a deep arm-triangle choke to end the bout and claim the inaugural light heavyweight title. After a brief striking exchange, Gracie took Pasternak to the ground from the clinch. Pasternak tried his best to escape but within moments the choke was on and Pasternak was put to sleep.

In a highly-anticipated featherweight contest, former ONE Championship belt holders Narantungalag Jadambaa of Mongolia and Kotetsu Boku of Japan went to battle to the delight of the raucous crowd. Jadambaa showcased his complete arsenal of techniques by continuously staggering Boku with powerful strikes, while controlling his Japanese opponent with high-level wrestling. The fight-ending sequence came when Jadambaa was able to take Boku down to the mat, executing a crafty Von Flue choke to put Boku to sleep.

In what was a very good night for the Lee family, younger brother Christian continued his rise through the ranks with his fourth straight stoppage victory, turning in a sensational performance against the Philippines’ Cary Bullos to win by submission.

Lee started off with his familiar unorthodox stance, peppering Bullos with sidekicks. When Bullos tried to close the gap, Lee took advantage by latching onto the Filipino’s neck. Within moments, Lee was able to drag Bullos to the ground, sinking in the D’Arce choke to force the tap.

In a clash of colossal middleweights, Tatsuya Mizuno of Japan, stopped Egyptian Wushu champion Mohamed Ali in the second round of a scheduled three-round bout.

Hometown favorite Amir Khan turned in a dominant performance, defeating Taiwan’s John “The Blade” Chang by technical knockout in the first round of a lightweight bout.

Likewise, Singapore’s Benedict Ang put in a workman-like effort, pummeling his opponent, Jimmy Yabo of the Philippines, from the mounted crucifix position to force a verbal submission.
