'You can't be serious!' Top six on-court tennis controversies
From John McEncroe to Nick Kyrgios and the usually mild-mannered Tim Henman, tennis stars' emotions can sometimes get the better of them on the court. But it's not always the players who are involved.
John McEnroe, Wimbledon 1981
US tennis legend John McEnroe was famed for his regular outbursts on the court - and one of the most memorable came in at Wimbledon in 1981. After a line-call, the volatile McEnroe smashed his racket on the ground (having already broken one) and screamed at the umpire: "Man, you cannot be serious!" After another call a few minutes later, he raged further: "You guys are the pits of the world!"
Serena Williams, US Open 2009
A set, 5-6 and 15-30 down in the US Open semifinal, Serena Williams committed a foot fault, making the score 15-40 and giving opponent Kim Clijsters match point. Williams shouted at the line judge, who then reported that Williams had threatened to "kill her." The umpire called a code violation and awarded the match-winning point to Clijsters. Williams remains adamant she did nothing wrong.
Tim Henman, Wimbledon 1995
Tim Henman was often considered too nice to be ranked among the game's true greats, but he showed a nastier streak during the doubles tournament at Wimbledon in 1995. Frustrated after losing a point, Henman smashed a tennis ball which hit a ball girl in the head. He protested that it was an accident but, in true British sporting fashion, accepted he was responsible and was duly disqualified.
Viktor Troicki, Wimbledon 2016
Serbia's Viktor Troicki was furious at Wimbledon 2016 when the umpire judged opponent Albert Ramos' serve to be in, giving the Spaniard match point at 40-30. But Troicki, absolutely convinced the ball was out, screamed "What!?" at the umpire, before launching into a rage, calling the umpire "an idiot, the worst in the world! The worst ever! You didn't see anything today! You made 30 mistakes!"
Nick Kyrgios, Australian Open 2017
Australia's Nick Kyrgios is no stranger to controversy and suffered a complete meltdown at this year's 2017 Australian Open. Having lead 6-1, 7-6, he then lost his cool and spent the next three sets berating himself and his team, and proceeded to lose the match to Italian outsider Andreas Seppi. Screaming "What do you want me to say!?", the general response appeared to be: "Less."
The wrong anthem - USA vs Germany, Fed Cup 2017
Ahead of a Fed Cup match between Germany and the USA in Hawaii, event organizers sang an out-dated, Nazi-era version of the German national anthem. Before the match a soloist sang the first verse of the "Deutschlandlied," beginning with the words "Germany, Germany, above all." The modern national anthem features the third verse only. Germany's Andrea Petkovic said it was "horrifying and shocking."
