UFC 238 video: Calvin Kattar floors Ricardo Lamas in first round

“The Boston Finisher” is back to living up to his nickname at UFC 238.

Calvin Kattar picked up the biggest win of his UFC career on Saturday, punching out one-time featherweight title challenger Ricardo Lamas in the first round to kick off the UFC 238 ESPN preliminaries:

After landing a clean 1-2 combination, Kattar (20-3) followed with a flurry of ground-and-pound to force the stoppage at the 4:06 mark of round one. It was the second straight first-round TKO for Kattar, who went without a finish from 2011-2017. Kattar’s last three wins have all come before the final buzzer.

Lamas (19-8), who was fighting in front of a hometown Chicago crowd, fell to just 1-3 in his last four outings after suffering his fifth career KO loss.
