30-27 Gomi. Sanchez did nothing of note throughout the fight. A few jabs, a few front kicks, the Jon Jones side kick to the knee, and a hideous flying knee. A performance that was more show than fight.
Gomi on the other hand ate that belly up in the first and second rounds, established a jab that actually did something, and had some effective kicks. Aside from the first round the Grappling was controlled by Gomi, even then Diego's takedowns had nothing following them.
Edit: wow, what a terrible decision. Diego by split? He did nothing. Not with his takedowns, not with his striking, not with his anything. I guess being pushed back to the fence and running away while gimmick kicking is what wins rounds now.
