This is a purely a judgement call. If wrestler A has lost control and wrestler B is face to face this would be an escape. Many escapes are missed because of "waiting to see what develops." The more prepared you are the easier this call is. As I have mentioned before, control, or loss of control, is sometimes felt rather than seen. The more an official works matches, studies the rules and casebook, and attends clinics the easier the judgement becomes.
