UFC women’s bantamweight champion Ronda Rousey defends her crown for the fifth time against No. 1 contender Cat Zingano at UFC 184 in Los Angeles. The unbeaten Rousey has ripped through all contenders at 135 pounds, needing just a combined 82 seconds to defeat her opponents in the two most recent title defenses. Colorado’s Zingano is also undefeated as a pro, and after back-to-back knockouts she has plenty of momentum on her side.
