But in defeating “The Prodigy” via unanimous decision in the UFC 137 main event Saturday night, Diaz’ first UFC bout since 2006 sent shockwaves through not only the Mandalay Bay Events Center, but through the MMA world, as he apparently retired Penn and put himself squarely in line for a shot at Georges St-Pierre’s welterweight title.
