In the history of UFC trilogies, the fighter who emerged victorious in the second bout has found success in the rubber match roughly two-thirds of the time.
Cain Velasquez (13-1 MMA, 11-1 UFC) continued the trend in Saturday's UFC 166 pay-per-view headliner with a performance against Junior dos Santos (16-3 MMA, 10-2 UFC) that nearly mirrored his UFC 155 victory over "Cigano."
Similar to the previous meeting, Velasquez dominated the fight from bell-to-bell with his relentless offensive attack. However, this time he stopped his Brazilian foe by knockout to retain the heavyweight title and to win the epic trilogy.
Velasquez's second consecutive title defense ties him with Randy Couture, Tim Sylvia and Brock Lesnar for the most ever in the weight class, and just one more defense of the belt will make the 31-year-old the most decorated heavyweight champion in company history.
