Australian Open 2013: Jerzy Janowicz has on-court meltdown as he goes 'nuts' over line call The 24th seed screamed his discontent at a line call when he led 9-8 in the tiebreaker of his 6-7 (10/12), 3-6, 6-1, 6-0, 7-5 triumph. "The umpires, they're making so many mistakes," Janowicz said. One of the most important mistakes was set point in the tiebreak, 9-8. Was a shanked forehand from Devvarman. The ball was really slow, it was clean out. Sometimes it happens like this. Sometimes I have a problem to control my emotions, but I'm trying to work on this. Asked if he had ever gone "as nuts" in a match, Janowicz smiled: "Yeah." On whether it was the first time he had struck an umpire's chair, he replied more sheepishly: "Maybe." Devvarman said he had never witnessed an outburst like the one delivered by Janowicz, whose tantrum was attracting a stream of YouTube viewers shortly after the match. An outburst by Marcos Baghdatis at the Australian Open last year, when the Cypriot smashed four racquets during a changeover, has since had 1.4 million hits on YouTube. "I was thinking dude, relax," Devvarman said. He is a friend and I have played him before. He got a little upset with a couple of calls.
