ONE Championship came away with two events over the weekend, as Christian Lee won the welterweight title at one of them.

Lee, the reigning lightweight champion, downed Kiamrian Abbasov for the belt in the main event of ONE on Prime Video 4. The event took place from the Singapore Indoor Stadium.

Prior to the bout, Abbasov failed to pass weight and hydration, which caused him to lose the welterweight belt on the scale. Only Lee was eligible to win the World Title, and he did so with an impressive display of striking and grappling.

Abbasov started the first round with a huge offensive onslaught, hurting and rocking Lee with a barrage of strikes that had the 24-year-old reeling. After surviving, the Singaporean-American came roaring back in round two, swarming Abbasov with a flurry of combinations. Lee also snuck in a couple of solid takedowns to do some damage on the ground.

After a relatively nonchalant third round from both men, action picked up again in the fourth, as Lee unloaded a flurry of power shots. He then stung Abbasov with a series of right elbows as the Kyrgyz warrior tried to defend himself.

With Abbasov on his back, Lee teed off with more ground-and-pound that forced referee Herb Dean to call a halt to the contest. In addition to the ONE Welterweight World Title, Lee also won a US$50,000 bonus.

In the main event of ONE 163, Thai veteran Petchtanong Petchfergus put together one of the best performances of his career, upsetting divisional king Hiroki Akimoto via split decision to capture the ONE bantamweight kickboxing title.
