Ryota Murata (N/a) Vs Sanosuke Sasaki (11-2, 5)
In 2012 Ryota Murata made a statement by winning an Olympic gold medal, the following year he turned professional. His professional journey began with his pro test bout which saw him fighting against former Japanese Middleweight champion Sanosuke Sasaki. Although Murata wasn't yet a licensed professional it was clear that he was a level above the Japanese domestic fighters and by the end of this "bout" it was clear that Sasaki was relieved he only had a few to go with Murata.
Notably this was held on the same show as Naoya Inoue's bout with Yuki Sano.
