Not sure how the disaster there is going to effect their preperation. But, assuming they have maintained some routine and are mentally focused on these fights, I think their is great value here.
Kawajiri is arguably Japan's strongest wrestler. Melendez has the hand speed and but Kawajiri has the power advantage imo. I think this fight is close to even and Kawajiri should be a slight favorite if this fight was in Japan. To win 1u for me.
Beerbohm prides himeself on his scrabbling ability and wins most fights with his grappling. Grappling with Aoki for 3 rounds isnt going to turn out well imo. Aoki also has a reach advantage and can probably outstrike Beerbohm smiliar to the Ribeiro fight.
