Four of the UFC’s past five main events have seen the underdog emerge victorious.

That trend continued in Saturday’s UFC 173 pay-per-view event, where longtime 135-pound titleholder Renan Barao (32-2 MMA, MMA, 7-1 UFC) lost his bantamweight championship to T.J. Dillashaw (10-2 MMA, 6-2 UFC) in a shocking defeat.

Las Vegas’ MGM Grand Garden Arena was the scene of Dillashaw’s triumph as the 28-year-old outclassed his Brazilian counterpart in one of the greatest striking performances ever in a UFC championship fight.

Dillashaw’s title-winning effort capped off a night of tremendous victories. For the numbers behind some of those performances, here are 45 post-fight facts about UFC 173.
