Is Calvin Kattar Irish?

UFC featherweight Calvin Kattar is not Irish. Nicknamed 'The Boston Finisher', Kattar hails from Methuen, Massachusetts.

It is popularly known that people of Irish ancestry make up the largest ethnic group in Massachusetts. However, Kattar is of American descent with no links in Ireland. He was born on 26 March 1988 to James Kattar and Sandra Kattar.

Kattar made his professional MMA debut in June 2007 and joined the UFC ranks 10 years later. ‘The Boston Finisher’ was called upon by the UFC when Doo-Ho-Choi was forced to pull out of his fight against Andre Fili in July 2017. Kattar impressed in his UFC debut and went on to amass a 7-4 record under the promotional banner. His overall MMA record currently stands at 23-6.

Kattar most recently headlined the UFC on ESPN 37 card in June, where he dropped a split decision against Josh Emmett in a close fight.
