Jack Sock loses plenty of fans with his treatment of umpire

Jack Sock used to come across as one of the nicest guys in tennis.

But his nasty side came out this week, when he was knocked out in the first round of the French Open thanks to a 6-7 (4), 6-2, 4-6, 7-6 (5), 6-3 defeat to lucky loser Jurgen Zopp on Tuesday. Sock let the frustration get the better of him on several occasions as he berated umpire Paula Vieira Sousa for a series of admittedly incorrect calls against him. The American eventually asked for the official to be replaced after branding her "atrocious". https://twitter.com/cjzero/status/1001504498890797056?ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fdeadspin.com%2Fajax%2Finset%2Fiframe%3Fid%3Dtwitter-1001504498890797056%26autosize%3D1 After losing the fourth-set tiebreaker, Sock lost the head entirely and seemed more focused on publicly humiliating Sousa than his strategy. "I can do whatever I want as a player. You wouldn't be here without me. Now I'm going to the toilet," Sock said. Even after the dust had settled on his defeat, Sock refused to express any regret for the way he'd behaved on court. https://twitter.com/stu_fraser/status/1001521721575436288?ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fdeadspin.com%2Fajax%2Finset%2Fiframe%3Fid%3Dtwitter-1001521721575436288%26autosize%3D1 It's a far cry from the lovable Sock who once displayed incredible honesty by telling opponent Lleyton Hewitt to challenge a call that had wrongly been ruled out and the man who sought out a young fan who had a towel ripped away from him after Sock had kindly thrown it in his direction. The 25-year-old will have some ways to go if he is to win back some of the fans he's lost with his outbursts in Paris on Tuesday. https://twitter.com/Tazzie_D/status/1001663034325073920 https://twitter.com/TheRealKingGaf/status/1001658072715087874 https://twitter.com/vje51/status/1001654225028382722 https://twitter.com/mgriffinv/status/1001653243762610176 https://twitter.com/TennisBlogger1/status/1001623777099337728 https://twitter.com/iggybach/status/1001616002830843904 https://twitter.com/cricket_fan_cz/status/1001606068735172609 https://twitter.com/Garbologist_/status/1001605179551043584
