Also on tap is a rubber match for the Strikeforce lightweight championship as Gilbert Melendez defends his title against longtime rival Josh Thomson.

A potential light heavyweight title eliminator is also featured as Rafael “Feijao” Cavalcante looks to avenge his 2010 loss against emerging contender Mike Kyle.

It all goes down from the HP Pavilion Saturday on Showtime and here’s a closer look at what we can expect:

Main Card (on Showtime):

-Josh Barnett (31-5) vs. Daniel Cormier (9-0)

After kicking off in February 2011, the Strikeforce Heavyweight Grand Prix tournament finally culminates Saturday as unlikely finalists Barnett and Cormier vie for the top prize.

Barnett, 34, is unbeaten since his run in the Pride Fighting Championships, riding an eight-fight winning streak that includes victories over Jeff Monson, Pedro Rizzo and Gilbert Yvel.

To make it to the finals, Barnett used his bread and butter to submit strikers Brett Rogers and Sergei Kharitonov with arm-triangle chokes.

Since a knockout loss to Rizzo at UFC 30, the first setback of his career, Barnett has lost to only two men widely recognized among the greatest heavyweights of all time during their primes, Mirko “Cro Cop” Filipovic and Antonio Rodrigo Nogueira. Meanwhile, Barnett has enjoyed victories over Randy Couture, Semmy Schilt, Aleksander Emelianenko and Mark Hunt.

There were other outstanding bouts on the card as well.  It was an intriguing night as each bout was a life drama unto itself. Young careers blossomed while some older careers met their end. Boxing is a young man’s game with very few exceptions. Aging is never kind to a boxer who still wants to live his dream.

Former Canadian cruiserweight champion Frank White, in what may have been his last pro fight, was on the receiving end of a hellacious beating, administered to him by a much younger, stronger and better skilled fighter named Denton Daley. The majority of professional boxers in the world are similar in style and record to Frank White. What makes White standard apart from the rest of those fighters plying their trade is his sportsmanship and his never say die attitude.

Koji (1-1 Legend, 6-3-2 overall) has won four of his last five fights including a dramatic “Submission of the Night” victory over Damien Brown at Legend 7. Always entertaining fan favorite and Australian knockout artist Rob Hill (2-2 Legend, 11-5-1 overall) will aim to derail Ando’s title hopes. Hill is coming off his own “Submission of the Night” performance against Yusuke Kasuya at Legend 8 and will be looking for another statement victory en route to a title shot.

“The road to the title goes through Ando,” said Hill. “I’m pumped up and ready to take him out to get a shot at the belt. I’ve got a flair for the dramatic, and I know I’ll win big.”
