Brydan lost to the Thai wildcard in straight sets, I think he has lost a lot of confindence after that match against Udomchoke in Davis Cup.
He just couldn't control his anger. He threw the racket so many times and got
several warnings. Actually, his game was a lot better.
By the way, in the match against WC Thai, Brydan injured his ankle during the match.
So he couldn't move well right after.
