Jake Shields made quick work of Brian Foster last night in their welterweight match at World Series of Fighting 17, and now one of the most feared submission artists in MMA awaits.

But Shields, the American Jiu-Jitsu expert who ran his record to 31-7-1 with one no-contest, sounded anything but concerned after the main event in Edmonton, Alberta, Canada.

The prospect of fighting WSOF Welterweight Champion Rousimar Palhares, who has won his last three bouts by brutal twisting leg-locks? No problem.

“Palhares is holding my belt for me,” Shields said in a post-fight interview. “I’m going to go out there and whoop his ass!”

The Cesar Gracie disciple took Foster to the mat after a brief standup exchange early in the first round, and proceeded to showcase his superior jiu-jitsu skills. After a quick guard pass, an attempt at an arm triangle, Shields moved to the back where he secured a rear naked choke.

Shields’ arm may have been around Foster’s chin, but the pressure was enough. With Shields locked on his back with a body triangle, Foster tapped at 2:51 of the first stanza.

After the bout, it was announced, as expected, that Shields will next fight Palhares for the promotion’s title at welterweight.

The loss snapped a four-fight winning streak for Foster, whose MMA record drops to 22-7.  All but one of his losses have come by way of submission.

Shields has now won both of his WSOF bouts by first round submission.
