Question on Griffin vs. Sonnen

How did it go?

Sonnen winning, albeit not in dominating fashion, Griffin catchs Sonnen.

I believe that Sonnen claimed to be winning by GnP, but in a photo afterwards Forrest looked pretty fresh after winning.

everyone who was there that I talked to said Griffen wasn't taking much damage before the sub, although Sonnen was probably winning on points just for getting the takedowns and maintaining position

Thank you for the replies.

the fight was 23 minutes?
