• Following his Korean giant Hong Man Choi’s victory over Jose Canseco in the opening round of the Dream Super Hulk Tournament, US basketball star (and MMA fan) Shaquille O’Neal expressed interest in facing off against the 7-2 Choi, after his basketball career had ended. Prior to his bout Tuesday against Ikuhisa Minowa at Dream 11, MMAFanhouse asked Choi if he was open to that match up, to which he responded, “Yes, if there is a chance.” It would be no surprise if FEG promoted this fight for one of it’s Dream events, once Shaq does leave the NBA.

8,867 fans attended the Showtime-televised event at the Scottrade Center in St. Louis, Missouri.

Following the win, which improved Shields’ record to 23-4-1, the former EliteXC welterweight champion called for a middleweight title bout against Strikeforce champ Cung Le. Le, however, is not expected to defend his title for the indefinite future while pursuing a movie career and Shields may be forced to face another opponent for an interim title before Le returns. Lawler, a former EliteXC middleweight champion, falls to 18-5 following the defeat.

Heavyweight contender Brett Rogers needed just 22-seconds to knockout Andrei Arlovski with a flurry of punches in the Strikeforce: Lawler vs. Shields co-headliner. Rogers, who improved to 10-0 with the win, will next meet Strikeforce heavyweight champion Alistair Overeem on a future Strikeforce card, while Arlovski’s future is less certain after falling to 15-7 with his second-straight knockout loss.

In other main card action, Nick Diaz overwhelmed Scott Smith with punches over two full rounds before forcing Smith to tap to a rear naked choke in the third and Joe Riggs and Mike Whitehead picked up unanimous decision victories over Phil Baroni and Kevin Randleman respectively.

Kevin Randleman

PRESS RELEASE — Two-time NCAA Division I National Wrestling Champion and former UFC Heavyweight Champion Kevin “The Monster” Randleman (17-12) will make his long-awaited return to mixed martial arts (MMA) action when he squares off with fellow grappling expert Mike Whitehead (23-7) during the live SHOWTIME® telecast of Strikeforce: “Lawler vs. Shields” from the Scottrade Center in St. Louis, Mo. on Saturday, June 6.

Making his first appearance in over a year and his debut with Strikeforce, the 37-year-old Randleman of Columbus, Ohio will attempt to reclaim the glory he achieved almost a decade ago when he was crowned UFC heavyweight champion after scoring a knockout on Pete Williams at UFC 23 on November 19, 1999.

A tremendous athlete with explosive power, Randleman captured back-to-back NCAA national wrestling titles in 1992 and 1993 while competing for Ohio State University. His stellar collegiate career gained him entry into the school’s Hall Of Fame in 2004.

On October 22, 1996, Randleman made his professional MMA debut in Brazil where he stopped Luiz Carlos Macial in the first round of action. After amassing a 6-2 record, he entered the octagon for the first time at UFC 19 on March 5, 1999 and pulled off a stunning upset of MMA and kickboxing legend Maurice Smith.

After retaining his UFC title with a unanimous decision over Pedro “The Rock” Rizzo on June 9, 2000, Randleman was stopped by Randy “The Natural” Couture two months later.

In 2002, Randleman joined the ranks of Japan’s elite Pride Fighting Championship and enjoyed initial success by overcoming his first three opponents.

Randleman’s career came to a screeching halt three and a half years ago when he contracted a severe fungal lung infection that required surgery. The illness return shortly thereafter, thus delaying his return further.

Like Randleman, the 27 year old Whitehead has shined on the mats, achieving NJCAA All-American honors in 2001 while wrestling for North Idaho Junior College and, later, two-time All-American honors while competing for Southern Oregon University.

In his last start on October 29, 2008, Whitehead submitted Leo Pla in the first round of their matchup in Kansas City, Missouri. The victory returned Whitehead’s name to the win column one month after he gave up a unanimous judges’ decision to Renato “Babalu” Sobral. The loss to Sobral ended Whitehead’s 13 fight win streak that dated back to March 2006.

A native of Oregon, Whitehead has taken residence in Las Vegas, Nevada, the fight capital of the world to train amongst the sport’s best competitors. He recently parted ways with the Xtreme Couture camp and found a new home at the all-new training ground of superstar and former world champion Wanderlei “The Axe Murderer” Silva.

In 2005, Whitehead was cast on the second season of Spike TV’s smash-hit reality series The Ultimate Fighter. He has since conquered fellow octagon veterans Krzyysztof Soszynski and Vernon “Tiger” White as well as former UFC champion and HBO documentary subject Mark Kerr, whom Whitehead stopped with strikes in the first round of their meeting in Portland, Oregon on November 2, 2006.

Fresh off their respective thrilling Strikeforce wins on April 11, Brazilian Jiu-Jitsu black belt and boxing stylist Nick Diaz (19-7) and knockout artist Scott “Hands of Steel” Smith (17-5) will face off with each other special 180-pound showdown

FRANK SHAMROCK

• “Someone asked me the other day how my comeback was going so I guess I’ve come back. I love fighting. I love this art. I want to thank Nick Diaz for the opportunity and just warn him that when I punch his head and he lands in the second row he’ll need someone to catch him.
• “I’m not going to show a lot of things I have in the past. This time I’m just showing up to smash some people and make a few dollars.”

NICK DIAZ

• “Training has been going great and I am very happy with it. I am clear-headed and ready to fight.
• “I feel I am the perfect candidate for this fight. Shamrock thinks he can beat guys with styles like me.
• “I don’t care about the weight. I feel more energetic. My strength is great. I hit harder. I like this fight because I will be able to control what goes on when we’re on the ground.
• “Frank can talk all he wants, but I’m going to beat him up. Let’s see how much he fights back.’’

JOSH THOMSON

• “There is much more pressure on me this fight. There was no pressure when I fought him the last time; I was just the challenger.
• “But now that I am Strikeforce champion, I have to work ever harder and be more prepared for anything and everything.
• “I don’t feel I got the respect I should have after beating Gilbert. But that doesn’t bother me. As long as I know I am giving the fans what they want – and the fans know what they will get when I fight – then I am fine.
• “Our second fight will really showcase our new skills, things people haven’t seen in the past. It will be more action-packed and fast-paced.
• “Gilbert is someone I admire and I’m actually dreading this fight. I know it’s going to go for five rounds and will be full of action. There will be a lot of blood, sweat and tears shed to get ready for this fight but it’s going to be fun come April 11.’’

GILBERT MELENDEZ

• “It is definitely a great thing for me to have a chance to redeem myself for my only loss and to do it on SHOWTIME is a dream come true. This fight will give both of us a lot of exposure.
• “All I will say about our first fight is that Josh trained harder and was the better man that night.
• “Losing is never a good thing, but you live and learn from experiences and that fight has made me train even harder. I did the best I could in our first fight, but I feel I am a better fighter now and will do better on April 11.
• “This time, I am going to take it to him, dictate the pace and make him fight me. This time, I am going to fight my fight.’’

SCOTT SMITH

• “I am very excited about this show and excited to be able to ride this new wave. This is going to be a great fight, one of the best of the night.
• “I totally respect Benji. This will not be easy. I’ve changed a few things in my fighting.
• “I’m trying not to get hit too much. People like to see fun fights and our fight will definitely be a fun fight to watch.’’

BENJI RADACH

• “He has been in a lot of wars but by no means do I think they have taken a toll on Scott. He is always in top shape and always comes to battle.
• “My advantage is, I think I am faster and maybe a little better wrestler. My quickness is going to be key.
• “But the bottom line is to be better and win the fight no matter where it goes.’’

CRIS “CYBORG” SANTOS

• “It’s really exciting what SHOWTIME has done for women’s MMA and I am proud that they want me back on their next show. I am not looking past my opponent, but the fighter I want is Gina Carano.
• “People have been talking about us fighting so I think it is only a matter of time. I think we both want the fight and I know it is a fight the fans would love to see.
• “I can’t wait for April 11 and I can’t wait to fight Gina Carano.’’

ROBBIE LAWLER

• “Everybody knows I am always ready and willing to fight anybody, anytime, any place so I am just looking forward to getting out there and fighting.
• “I might be bigger, but it sure doesn’t look it when we stand side by side. This will be my first fight since July but I’m always in the gym and I stay in shape. So I’ll be 100 percent.’’

JAKE SHIELDS

• “I am super excited about this fight and this opportunity. I’ve always wanted to fight the top level guys. That’s not to say the guys I’ve fought recently weren’t good fighters because they were.
• “But Lawler is a high-profile fighter, a top-five middleweight. So this is a real challenge for me and a fight that has me highly motivated.
• “I am very happy to be fighting on SHOWTIME again. This is definitely going to be a great fight and I am super happy to be part of this. Strikeforce is going to be doing a lot of good things in the future.’’
