Double G FC 2 was not a good night for the hometown heroes.

The show went down on Saturday night at the JangChung Arena in Seoul and all the Korean fighters at the top of the bill were either knocked out, thoroughly dominated or disqualified.

Yet, the biggest surprise was the dismantling of Yang Dongi in the headliner by Cally Gibrainn de Oliveira. The South Korean slugger started fast but his cardio eventually failed him and that is when the Brazilian took over to find his chin.

Both competitors met in the middle to begin the first round and Oliveira initiated with a big swing and a miss. Yang countered and then rushed forward for a powerful double leg takedown.

Panic mode

Yang immediately got control and slid into north-south position and dropped down hammers to the cranium. The Brazilian was able to absorb some damage to get back to his feet but Yang was still hanging on his back.

While Yang had his hands locked around the waist, Oliveira locked on a kimura grip and they dropped to the mat. He powered through and had the submission in deep which put Yang in panic mode.

The Korean brawler flipped over and they scrambled to their feet. At this point, Yang looked visibly fatigued and was gasping for air.

They commenced to swinging wildly at each other. Oliveira connected with four consecutive right hands and the last one planted Yang on his backside.

Toe to toe

Although Yang ate some more strikes on the ground, he got back upright and stood toe to toe with his foe. However, this would not prove to be a smart decision on his part.

While Yang was throwing the kitchen sink, Oliveira only needed his right fist. With a little over a minute left in the first, Oliveira dropped Yang again with the same punch.

Once more, Yang got back up and brawled some more. After a few exchanges the UFC veteran lunged forward and was caught with a counter that instantly immobilized him, forcing the referee to immediately end the contest.

The former Heat heavyweight champion gets back on track after losing his title earlier this month to Satoshi Ishii in Japan. He moves his record to 4-1 and notches a huge performance over a seasoned Korean veteran.

Yang (14-4), on the other hand, loses for the first time since 2012 which was the end of his first stint in the UFC. He has said after every fight that he would drop back down to middleweight, so perhaps this experiment of being a heavyweight is finally over.

Disappointing debut

In the co-main event another UFC veteran, Jeon Chan-Mi, made her promotional debut against Shizuka Sugiyama. The Korean was returning after an 18 month competitive absence and jumping up a weight class, which in hindsight was looks like a bad idea.

Jeon missed weight the day before by 1kg and was deducted three points per round throughout the fight. This did not matter due to Sugiyama dominating every round with strong grappling as well as effective clinch work to walk away with the clear unanimous decision.

Sugiyama (17-6-1) erases the memory of the 11 second knockout loss in her last outing at Rizin: ‘Heisei’s Last Yarennoka’. Meanwhile Jeon (5-3) drops her third straight decision defeat and goes back to the drawing board.

Painful ending

In the oddest moment of the night, Ahn Sang-Il was disqualified for multiple low blows inflicted on Jason Radcliffe in the first round.

The first two infractions happened along the fence in the clinch with knees. Ahn who is known to be a striker opted to clinch and use knees which landed on the cup more than three times.

The final shot came when Ahn (5-7-1) was on his back and upkicked Radcliffe (14-7) below the belt. The London native immediately dropped to the ground in agony and shortly thereafter the referee called an end to the contest.

Double G FC 3 is slated to happen later this summer and Lim Hyun-Gyu versus Kim Jae-Young will likely be the headliner. The winner will move on to challenge for the inaugural middleweight title.
