6. Anderson Silva vs. Chael Sonnen – UFC 148
In the 2010 ‘Fight Of The Year’, reigning middleweight champion Anderson ‘The Spider’ Silva went to war with the colorfully worded Chael ‘The Bad Guy’ Sonnen in the main event of UFC 148 for the 185-pound title.
Sonnen earned the opportunity to step into the Octagon with Silva earning a unanimous decision victory over Nate Marquardt at UFC 109.
The former All-American wrestler had gotten under Silva’s skin with his brash trash-talk, and was determined to leave California as the new undisputed middleweight champion.
To many’s surprise Sonnen came into the bout dominating Silva with his superior wrestling ability, and bludgeoning him with some extensive ground-and-pound strikes.
Sonnen seemed to be only one round away from becoming the new 185-pound champion, as he once again had Silva in trouble on the mat with just minutes to go. Silva, however, would pull off a miraculous triangle choke that would force Sonnen to tap out and cost him his chance at becoming UFC champion for the first time in his MMA career.
