He was finding Vitali with ease... But if you go from a shot - whether it's concussive damage of the shot, or just the fact that your legs aren't strong enough to keeo balance... It doesn't matter, it's 10-8. He lost that round, the fact that he quit is moot.

He was picking klit off, but I'm not convinced that this wasn't because Vitali had little respect for Solis' resistance.
