This fight, which took place on April 5th 2014 was Kamegai's most recent bout and saw him defending his OPBF Welterweight title for the first time. It was viewed as a mismatch from the second it was announced and proved to be very every bit of a mismatch with Kamegai having nothing to fear from the South Korean, who tried to fight back but was simply out gunned and eventually stopped.
It wasn't the most impressive of performance by Kamegai, there was nothing especially great about it, but he dealt with an over-matched title challenger like a champion is supposed to and stopped him with a solid body shot that simply destroyed what was left of Yang's fighting spirit.
If you've seen much of Kamegai ahead of his fight this weekend this is worth a watch just to get some eyes on him but is far from Kamegai at his best.
