TORONTO - Nick Diaz secured a welterweight title shot after battering B.J. Penn en route to a unanimous decision victory in the main event of UFC 137 in Las Vegas Saturday.

But his successful octagon return was quickly overshadowed by Penn announcing his retirement from MMA.

“Hats off to Nick Diaz; he’s the man,” a bloodied and bruised Penn said to Joe Rogan. “Joe, this is the last time you’re going to see me in here.

“I got a daughter at home and another on the way. I don’t want to go home to them like like this.”

Following his victory, Diaz immediately called out Georges St. Pierre.

“I don’t think Georges is hurt; I think he’s scared to fight,” Diaz yelled. “Where you at, Georges?

“B.J. is the man. I always loved watching him fight.”

Cheick Kongo derailed the surging Matt Mitrione, earning a dull unanimous decision in the co-main event.

Mitrione continually applied pressure in the first round, backing Kongo against the fence. But just when you thought he was going to let his hands go, he would step away, allowing Kongo to restart.

The second stanza saw Mitrione land a few power shots, but Kongo responded with leg kicks and jabs. The final frame was all Kongo, who slammed Mitrione to the mat and unloaded with vicious ground-and-pound.

Following his third consecutive knockout loss, Mirko (Cro Cop) Filipovic retired from MMA.

Prior to the bout, Filipovic said he wanted to show the “old Cro Cop” one last time, but succumbed to the ground-and-pound of Roy Nelson in what was otherwise a competitive bout.

“I said before this fight, this was going to be my farewell fight,” Filipovic said. “Unfortunately I didn’t get the victory. Roy was the better fighter tonight.

“I was treated like a king (in the UFC) by management and the fans. I’m sorry I blew it up. What can I say?”

Nelson said it was an honour to compete against Filipovic

“Everybody give it up for Cro Cop; he’s given enough as a fighter in MMA,” Nelson said. “It was awesome to compete against a legend I want to thank Lorenzo Fertitta and Dana White for the opportunity, and Joe Rogan for calling me fat.”

“I called you fat because you are fat,” Rogan responded.

Nelson then called out the winner of the upcoming heavyweight title fight between Cain Velasquez and Junior dos Santos.

“I’m going to pull a Chael Sonnen and call someone out. Who’s fighting in a couple weeks — Junior and Cain. I want the championship. I’m getting too old for this s***.”

Former WEC bantamweight title challenger Scott Jorgensen won a close, technical battle with Jeff Curran.

Jorgensen looked hesitant in the striking exchanges, focusing more on counter shots in order to avoid getting taken down by the submission specialist. However, Curran surprised him, landing some good shots, forcing Jorgensen to take it to the mat.

Curran threatened with numerous submission attempts and delivered numerous strikes off his back, but was unable to catch Jorgensen.

Following 15 competitive minutes, the judges awarded Jorgensen the unanimous decision

“I feel good,” Jorgensen said. “Sorry to everybody out there; you didn’t get to see the typical ‘Young Gun’ style.

“This is the first fight where I’ve ever had an actual jiu jistu coach. The sky is the limit from here.”

Japanese featherweight sensation Hatsu Hioki won a razor-thin split-decision over George Roop in his UFC debut.

Fans will likely debate the scoring in the first round.

Though Roop displayed superior striking in the opening minutes, Hioki managed to trip him to the mat and secure side-control. Hioki did little from the position, but controlled the action long enough to sway two judges.

Hioki then clearly won the second round, but was dominated in the third.

“He’s tough,” Hioki said to a chorus of boos. “He was stronger than I expected.

“Even though we are in a tough situation, Japanese MMA is not dead. We need to change.”

Donald Cerrone made quick work of Dennis Siver, submitting the German kickboxer with a rear-naked choke in the first round of the final preliminary bout.

Cerrone hurt Siver early with a head kick, but couldn’t go for the finish after getting tied up against the fence. When they separated, Cerrone dropped him with a straight right before securing back control to set up the submission.
