What was the controversy?
Fish hit a (probably) winning volley at the net, shouted out like an idiot "YEAH!!!!" before it bounced twice, Ebden got to the ball before it bounced twice and put it into the bottom of the net, but looked at the umpire to say "wtf was that". Umpire called it a hindrance caused by Fish yelling out, and awarded Ebden the point rightly. Fish argued stupidly for a few mins before giving up and getting broken.
Fish was arguing that his yelling had no effect on Ebden being able to make the ball, since he dumped it into the bottom of the net regardless. Which is fair enough, but that's not the rule, he yelled out in the middle of the point, therefore he loses it.
