At Shootboxing 2011 Act 1, Sengoku veteran Shigeki Osawa met the Japanese promotion's top domestic super featherweight, Hiroaki Suzuki.
Although Osawa wasn't able to win, it's interesting to see the success he was able to find in employing his grappling skill - particularly in light of the run that Toby Imada had in the promotion's 2010 S-Cup finals last year.
