Diaz immediately clinched an picked Alvin up with out bending down and took the fight to the ground. There he was working to land some punches and elbows inside Robinson's guard. Robinson covered up pretty well until Diaz gave him a chance to try for a guillotine choke while trying to stand up. When they stood up Diaz slammed Alvin down into his halfguard. Alvin held onto the guillotine for a bit and let go. Diaz then passed Alvin's guard to sidemount where he tried to transition into mount where Alvin reversed him. Diaz switched to a umoplata which Robinson turned out of and ended up on bottom again. He reversed it into Diaz's guard. This is where Diaz's long legs started giving Alvin problems. Diaz quickly locked in a tight triangle on a much shorter Robinson for a quick tap.

This was another decent test for Diaz which he passed with flying colors. I think if he fights Manny Gamburyan again, who he's more than willing to fight again to settle the dispute of who really won their first fight. I'll be picking Diaz in that fight, the size advantage will be too much and Diaz knows how to use it well.

Alvin Robinson is a decent hard working guy at 155, he should avoid fighting much taller guys in the division if he can help it.
