Here, another video edition of the Fourhand series. Let's get to it, shall we?
ERROR FROM THE CHAIR We are all too human. That said, chair umpire Damien Steiner biffed a call in the Novak Djokovic–Andy Murray quarterfinal match at the Sony Open on Wednesday, with Djokovic reaching over the net to hit an angled tap volley. Murray argued Steiner's call that the shot was allowed within the rules, which TV and Jumbotron replays showed was not.
Murray maintained to Steiner that Djokovic admitted to him that he had reached over, but the call had been made. Djokovic himself later told Brad Gilbert that he didn't know the rule on such a shot, distancing himself from what USTA 4.0-level league players stateside know to be the truth. Murray was subsequently broken for 5-6, and found himself on the short end at 7-5, 6-3 when it was over.
