"I kind of wore out as the fight went on," admitted Aina. "Nick stands up in front of you and doesn't give you a break. I definitely think I won the first two rounds, hands down, but that's why you can't leave things in the hands of the judges. That fight definitely tested my character and helped bring my game to the next level."

Since the loss to Diaz, Aina has reeled off two straight wins, his last being a first round submission of Ismael Gonzales on August 9, 2008.

Couture made her debut with Strikeforce on November 21, 2008 against Lina Kvokov. Couture, who recently added K-1 superstar Ray Sefo to her team of world-class trainers, quickly overwhelmed Kvokov with punch flurries and knee strikes in the first round of their matchup at San Jose's HP Pavilion. After Kvokov turned her back due to her inability to defend herself any longer, the referee ordered a stoppage at the 1:44 mark of the opening round, giving Couture a victory by way of TKO.
