Dean Lister has one predominant skill and that's his submission game.
If you don't go the ground with him. "The Boogeyman" can't win the fight. Yushin Okami peppered Lister with straight lefts on the feet and only went to the ground against Lister with him smashed against the cage. An area that would keep Okami safe from submissions.
Okami did take the chance of going to ground towards the middle of the cage with 3:50 left in the third. He did a good job of controlling Lister on the ground with punches and hammerfists. He unloaded a few big shots with 1:20 left in the fight. It was a lackluster close to the preliminary card. Okami wins on all three cards 30-27.
