Australian toppled Stefanos Tsitispas in a heated four-set thriller on Saturday Nick Kyrgios, ranked 40th in the world, thrives on his bad-boy image LONDON: Nick Kyrgios is back in action at Wimbledon on Monday after his dramatic victory against Stefanos Tsitispas as he closes in on a mouthwatering semifinal with Rafael Nadal. The maverick Australian toppled Tsitispas in a heated four-set thriller on Saturday, during which he called for the fourth seed to be kicked out of the tournament for hitting a ball into the crowd. Kyrgios called the umpire a “disgrace” as tempers frayed and the bad feeling spilled over into the post-match press conferences. The defeated Greek player said his opponent has an “evil side” and described him as a “bully,” comments that Kyrgios laughed off. Nick Kyrgios, 40th in the world, thrives on his bad-boy image and Saturday’s outbursts were not even his first of the tournament. But it will be a different challenge against American Brandon Nakashima, a player he has never faced before, and he may struggle to re-create the big-match intensity on Center Court. Kyrgios, who has only reached the quarter-finals of two Grand Slams, believes he has the firepower to win Wimbledon. “Round by round, if I keep doing my things, I feel good. I’m all right,” said the 27-year-old, who had vocal support from the crowd on Saturday despite his antics. Nadal, chasing the third leg of a calendar Grand Slam, found his rhythm in his third-round match against Italy’s Lorenzo Sonego and now faces Dutch 21st seed Botic van de Zandschulp. The 22-time Grand Slam champion, twice a winner at the All England Club, swept into the last 16 in straight sets after needing four sets to progress in his opening two matches. “My best match, without a doubt, since the tournament started,” said Nadal, the only top-10 player left in his side of the draw. “I made improvements today. Very happy for that. “I made a lot of things much better than the previous days, the determination, the way that I manage to play more aggressive, going to the net plenty of times.”
