RIZIN Trigger 2 results, videos: Kleber Koike survives early scare, taps Ulka Sasaki in main event

Kleber Koike envisioned himself submitting Ulka Sasaki in the main event of RIZIN Trigger 2 on Wednesday, and he eventually did it, but it was no easy task.

The former KSW featherweight champion improved to 4-0 under the RIZIN banner with his fourth submission finish, tapping Sasaki with a rear-naked choke in the second stanza after surviving a knockdown in the opening round.

Unbeaten since signing with the promotion, Koike is now hoping to earn a crack at the 145-pound gold against Juntaro Ushiku and join teammate Roberto Satoshi as RIZIN champions.

In the co-main, Kazuma Kuramoto, a former Shooto title challenger, scored a brutal knockout over Kenji Cato. He stopped with his knees on the ground in round 1.

The fastest finish of the night came in a featherweight showdown between Sora Yamamoto and Suguru Nii, with Yamamoto stopping his opponent in less than 40 seconds. Yamamoto dropped Nii by dropping his right hand, while Suguru Nii woke up in the backwards. He then continued with punches to knees and elbows until the referee declared it over.
