Serghei Spivac quickly submits Marcin Tybura in UFC main event
Andreas Hale: Serghei Spivac made short work of Marcin Tybura and secured a first-round submission Saturday in the main event of UFC Fight Night at the UFC Apex.
The fight was a rematch of their 2020 meeting when Tybura won a unanimous decision. This time, the tables were turned in dramatic fashion.
As the superior grappler, Spivac (24-6-1 MMA, 7-4-1 UFC) wasted little time closing the distance and dragging Tybura (25-9 MMA, 12-8 UFC) to the canvas. However, he gave up his position as Tybura transitioned into his guard. Little did Tybura know, Spivac had him right where he wanted as he swiftly snatched an arm and locked in an armbar that elicited the tap out at the 1:44 mark.
