Forgive Josh Thomson if he is a little grumpy today.

Following a third five-round fight with consensus elite lightweight Gilbert Melendez Saturday night, Thomson was on the wrong end of a split decision defeat, as “El Nino” kept his Strikeforce title in the co-main event of Strikeforce: Barnett vs. Cormier.

Thomson had defeated Melendez in 2008, but Melendez rebounded with a win over “The Punk” in ’09. Both of those bouts went the full five rounds, as did Saturday’s contest in San Jose. Many in the crowd also sided with Thomson, as there were plenty of boos when the scores were read.

“I (fought) like the first round was a 10-10 round. I should have went out and got it,” said Thomson, at the post-fight press conference. “It’s my fault I left it in the judges hands. The third was a close round, too. I thought I won that one, and then the fourth and fifth. But, you know, whatever.”

Strikeforce CEO Scott Coker and Melendez added during the press conference that there would be no fourth match between the two in the near future, leaving Thomson to ponder what happened for the time being.
