WSOF 13 results: Moraes submits Bollinger, Dugulubgov stops Caldwell in co-main event

World Series of Fighting (WSOF) returned to action on Saturday night (Sept. 13, 2014) at Sands Resort Casino in Bethlehem, Penn., and once again was shown live on the NBC Sports Network.

The WSOF 13 card was originally supposed to feature a bantamweight title fight with Marlon Moraes defending his title against Josh Hill. Unfortunately, Hill had to withdraw due to injury so the promotion found a replacement on short notice in Cody Bollinger. The fight would be set at a catchweight of 147 pounds due to the lack of time to prepare and Bollinger's history of weight issues, making it a non-title fight.

In the main event, Moraes proved to be too much for Bollinger to handle and easily outclassed the former Ultimate Fighter (TUF) contestant in all facets of the fight. After knocking down Bollinger with a left hand, Moraes controlled him on the ground and locked up a rear naked choke at the 1:35 mark of round two for the victory.

Bollinger had nothing for Moraes at any point during the contest. Moraes speed was the difference on the feet, as the Brazilian was able to land whenever he wanted to during most of the exchanges and knock Bollinger down in both of the first two rounds. Once Moraes got the fight to the ground, he was dominant there, as well.

After connecting with a left hand in the second, Moraes controlled Bollinger's head while looking to land a big shot on the ground. Bollinger began to give up his back, but held Moraes in half guard for a few moments. The champion started to lock in the finishing submission from there and once it was tight, he began to pass Bollinger's guard. He would finish the choke on his opponents back, but without having to get his hooks in, forcing the tap soon after.

"I beat Bollinger and he was 147," Moraes told Joey Varner after the fight. I actually fight 135 and I made 140. Who's the best 135'er in the world? That's me, man. I can beat anybody in the world. I'm the best at 135."

In the co-main event, Ozzy Dugulubgov brutally knocked out Keon Caldwell in the third round of their lightweight contest. It was arguably the best knockout from all of the cards over the weekend.

Dugulubgov mixed in some nice takedowns with his striking in the first two rounds and at one point was threatening with an achilles lock and then a heel hook, but Caldwell would avoid both. After a few exchanges in the third frame, Dugulubgov ducked under a right hand by Caldwell and came up with about as picturesque a right cross as you could ever hope or dream for. His fist connected perfectly flush with Caldwell's jaw, knocking him out cold for the first time in his career. Dugulubgov knew Caldwell was out and turned away as referee Bill Bookwalter waved the fight off at the 1:38 mark of the third round.

With the win, the Renzo Gracie lightweight improves to 6-2 overall. Caldwell drops to 9-3 and has lost two straight in the WSOF.
