5 times Brock Lesnar was considered an underdog heading into a match

#2 Brock Lesnar vs The Undertaker – WrestleMania XXX

Brock stares Death in the face

This one has to be one of the biggest shocks to ever happen in the sport of professional wrestling. At WrestleMania XXX the unthinkable happened - Brock beat The Streak. Until this match actually ended it had the feel of any other Undertaker WrestleMania match to that point. Logic stated that Brock would come within an inch of victory only for Taker to overcome the odds and beat The Beast.

Brock obviously walked into this match as the underdog. The Undertaker had a 20-0 streak walking into the match and most fans were sure that the Undertaker would retire undefeated at WrestleMania. Brock ended the streak clean to the shock of everyone watching (including Paul Heyman) and established himself as the most dominant force in sports-entertainment.
