They pop back up and Sakurai tags Diaz with an overhand right, prompting Diaz to push him against the fence. Shoulder shrugs and knees up the middle from Diaz in the clinch. They disengage and Diaz throws some of his trademark peppering jabs. Mach powers through a double-leg and into Diaz' full guard. Diaz trying to tuna-net-walk and isolate the right arm of Sakurai.
