Showtime website is now up and running for the Strikeforce April 11 event which will feature Shamrock vs Diaz in the main event, along with Scott Smith vs Benji Radach.  Other participants include Josh Thompson and Gilbert Melendez.

The event will take place at 10 PM ET/PT on Showtime and will consist of 5 total bouts.

Event Summary:

SAT APR 11 10PM ET/PT

Three-time world champion and mixed martial arts legend Frank Shamrock will make his dramatic return to the cage when he squares off in the main event with fellow knockout artist and resident bad-ass Nick Diaz in the main event of Strikeforce's first MMA event of the year, airing live on SHOWTIME from California's HP Pavilion in San Jose.

The matchup, which will be contested at a catch weight of 179 lbs, is a prime opportunity for the hard-punching, mouthy Diaz to avenge a devastating 21-second knockout that his trainer, Brazilian Jiu-Jitsu master Cesar Gracie, suffered at the hands of Shamrock in the main event of Strikeforce's historic MMA event in March 2006.

The telecast will feature up to five live fights including middleweight (185-pound limit) sluggers Scott "Hands of Steel" Smith and Benji "Razor" Radach, who will battle each other in a featured contest.
