Nick Kyrgios landed in hot water -- again -- after sledging Stan Wawrinka during their tennis match at the Rogers Cup in Montreal. He was later fined by the ATP, which then added a suspended punishment. Minas Panagiotakis/Getty Images
Kyrgios was the talk of Wimbledon earlier this year. His apparent decision to throw a game during his match with Frenchman Richard Gasquet drew widespread criticism and sparked a race row back in Kyrgios' native Australia. Ian Walton/Getty Images
During his match with Gasquet, Kyrgios was hit with a code violation by the umpire for audibly swearing on court. He responded by seemingly throwing Gasquet's next service game, drawing boos from the crowd. Exasperated, Kyrgios sought comfort from the ball boy and embraced him as he offered the Australian his towel. ADRIAN DENNIS/AFP/Getty Images
Although he rallied to take the fourth set, Kyrgios ultimately lost the fourth-round match 7-5 6-1 6-7 (7-9) 7-6 (8-6). Kyrgios was fined a total of $9,500 at Wimbledon. Ian Walton/Getty Images
Back in Australia, Olympic swimming great Dawn Fraser accused Kyrgios of setting a poor example for younger players, and her comments about his ethnicity have caused outrage. Fraser suggested the 20-year-old, whose father is Greek and mother is from Malaysia, could "go back to where their fathers or their parents came from." "We don't need them here in this country to act like that," added Fraser, 77. Ian Walton/Getty Images for Laureus/file
Fraser, who won four Olympic gold medals between 1956 and 1964, apologized "unreservedly," but not before Kyrgios had branded her a "blatant racist" in a post on his Facebook page.
