I feel the champ is scared, he got lucky with his victory with AJ, as he was underrated and he took his chance, all through their fight, you could see the surprise on AJ face, he didn't believe what he got. Now that AJ is all pumped up, Ruiz knows what's coming and as such, he knows he stands no chance of retaining the title. The whole world awaits a rematch, and knowing AJ, he's gonna fight Ruiz anywhere.
