Jesus Santos Aguilar opened UFC 290 by setting the bar high, and Shannon Ross very low.
The flyweight delivered a brutal one-punch knockout 17 seconds into his preliminary bout, the second fastest knockout in UFC flyweight history.
There really is no way to dress up the fight. Ross kicked half-heartedly to the body, then Aguilar responded with a left-leaf, then connected on a hard right that chilled his Aussie opponent. Aguilar did his best to let Ross know before running off to celebrate.
The win improves Aguilar’s record to 9-2 and puts him in contention for the knockout of the year. He was coming off a submission loss to Tatsuro Taira in February and most certainly bounced back on Saturday.
