Gregor Gillespie will always be a wrestler at heart, but his hands were lethal in his victory over Andrew Holbrook at UFC 210 on Saturday in Buffalo.

The unbeaten lightweight picked up the first knockout of his UFC career, stopping Andrew Holbrook with punches in just 21 seconds.

“That’s my first knockout, I can’t be happier,” Gillespie said in his post-fight interview. “We’ve been working a ton on my striking, and boy did it show off tonight.”

Gillespie (9-0, 2-0 UFC) never attempted a takedown, letting his combinations go from the start. He landed a left-right combination that staggered Holbrook, but didn’t get the knockdown. His next punch — a left hook to the chin — landed hard and sent Holbrook to the canvas.

“That’s [trainer] Keith Trimble right there, I’ve got to give him credit,” Gillespie said. “We worked on that step overhead inside hook a lot, and there it is, you can see it.”

Gillespie followed Holbrook to the ground, working around his guard and landing massive left and right punches before a series of hammerfists put Holbrook out cold.

Massapequa’s Gillespie fights out of Bellmore Kickboxing Academy, but being raised outside of Rochester and attending college in Edinboro, Pennsylvania, he was competing in front of a hometown crowd.

“I love this place, this is my home. Rochester, Buffalo, Edinboro, this whole snow belt, I love this place,” Gillespie said. “I’m so glad everyone could make it out here to see this fight happen.”
