Chael Sonnen is building a grappling promotion that is putting on a series of exciting bouts; bridging the worlds between competitive grappling and mixed martial arts. Submission Underground 3 did the same as competitors such as Chad Mendes and Antonio Carlos Junior faced off against some of the best grapplers in the game today. What resulted was a number of matches with exhilarating finishes.

The main event featured Dillion Danis facing off against AJ Agazarm in a grudge match to say the least. Neither fighter was able to submit the other, but they were both aggressive from the very start. Danis would suffer an eye poke that caused his eye to close, but that didn’t stop him from attacking Agazarm. In overtime, Danis had the fastest escape time which gave him the victory.

Agazarm downplayed the victory, blaming Danis for weighing in at 197 pounds, but Danis focused on a bigger name in Jon Jones. Jones competed at Submission Underground 2 and has shown an interest in competing in the promotion again.

Carlos Junior had perhaps the flashiest moment of the night when he hit a flying triangle on Garry Tonon. Tonon fought the position for an extended period of time but was forced to tap after being unable to find an escape. Carlos Junior became one of the few men to submit Tonon and rebounds from a recent defeat to Tonon’s teammate, Gordon Ryan.

Ryan was also in action on Sunday as he defeated Joe Baize with an armbar. Baize was aggressive during the match, attempting multiple leg attacks that Ryan was able to defend. Ryan would eventually find his way to Baize’s back where he would begin to attack with a reverse triangle and settle into an armbar that earned him the finish.

UFC featherweight Chad Mendes upset Jeff Glover as he earned his victory via rear naked choke in overtime. Glover was able to get Mendes to engage on the ground early, but was unable to find a successful attack before the end of regulation. That is where things got a little weird. Glover needed just 35 seconds to submit Mendes via a RNC of his own. Glover started celebrating but forgot the rule set allowed for Mendes to get an opportunity to submit Glover. If he could submit him in less than 35 seconds he would win. Mendes locked in the choke and got the tap faster than Glover and secured himself the victory.

UFC competitors walked into Submission Underground 3 as the underdogs but walked out with a 2-0 showing against some of the top grapplers in the sport today. The Submission Underground 3 replay is available for viewing on FloGrappling.com.
