Jairzinho Rozenstruik made life miserable for Shamil Gaziev.

Backed by a steady jab and solid takedown defense, “Bigi Boy” gradually weakened his opponent’s resolve en route to a technical knockout victory after four rounds in the UFC Fight Night 238 headliner at the UFC Apex in Las Vegas on Saturday. After beginning his professional tenure with 12 consecutive triumphs, Gaziev exited the ranks of the undefeated in discouraging fashion, while the 35-year-old Rozenstruik kicked off his 2024 campaign in style.
