LAS VEGAS » Anderson Silva won a unanimous decision in his comeback fight 13 months after breaking his left leg, dominating Nick Diaz at UFC 183 on Saturday night.

Silva (34-6) landed most of the big blows against the taunting Diaz, controlling a strange fight in the same MGM Grand Garden octagon where he shattered his lower leg with a kick to middleweight champion Chris Weidman’s knee in December 2013.

After months of rehabilitation, the 39-year-old Silva didn’t yet resemble the dominant champion who held the 185-pound belt for seven years. Yet he never faced much trouble from Diaz (27-10-1), who couldn’t back up his goading with consistent offense.

In a fight that resembled performance art at times, Diaz taunted Silva with increasingly elaborate gestures from the opening minute, daring him to fight.
