Watch: Molly McCann's jaw-dropping last-second armbar to win UFC Vegas 85!

Molly McCann made a successful strawweight debut at UFC Vegas 85, securing her first career submission victory in dramatic fashion.

The British fighter achieved the win in the dying seconds of the opening round, executing an armbar that forced Diana Belbita to tap out at 4:59. McCann had dominated much of the early action, showcasing her ground skills and relentless pursuit of a finish.

After delivering punishing ground strikes, McCann swiftly transitioned to the armbar, causing Belbita to submit as the round came to a close. This victory not only marks McCann's first submission win but also her first win in the strawweight division, breaking a two-fight losing streak. Her previous defeats had come via submission techniques targeting the arm. With this win, McCann's UFC record stands at 7-5.

For Belbita, it was her second consecutive loss and her third defeat in her last four fights. This defeat also marks her second loss to McCann, who previously defeated her via unanimous decision in a flyweight bout at UFC Boston in October 2019.
