Steve Day is less awkward here and gets in a few decent suplex throws, including a German, but again, he's clueless on the mat. Yamazaki doesn't do anything too fancy. Early on, he gets a cool legscissors takedown into the leglock and by the end of it, he's pissed and standing on Day in the ropes and firing off leg kicks until Day crumbles. After Day delivers the German, Yamazaki's able to slowly work his ay into an armbar for the submission. Meh. 

This was the most evenly matched bout of the night.  Cool spot where Day had Yamazaki in a Half Crab and Yamazaki hit Day with a heel kick to the head that just dropped him.  Good grappling throughout, Yamazaki tore Day up with kicks on the feet.  Yamazaki locked in an armbar that Day tapped to immediately despite him probably being able to reach the ropes if he was able to tough it out.
