Santos wins the hard way:
Round 1: The pair clinch in the corner early on until Yamada catches a low knee from Santos. Almost as soon as he's recovered, Yamada returns the favor with a kick to the Brazilian's groin. They finally get going and Yamada catches a Santos low kick and rushes him into the ropes... where he knees him in the groin. Santos collapses to the mat. That one looked bad. Referee Kenichi Serizawa issues Yamada a red card, deducting 10% of his purse and one point from him in this round. Santos connects with a head kick which sends Yamada shooting again. They clinch and Yamada knees him low yet again. Yamada is issued a second red card. One more and he's disqualified. They resume once more and Santos stuns Yamada with a straight, then cracks him with a knee as he's sitting on the mat. Serizawa stands them up. Yamada rushes Santos into the corner one more time and does the inevitable - knees him squarely in the balls. Yamada loses the fight and 30% of his purse.
