Nick Kyrgios suffers first upset at 2017 Wimbledon

Australian tennis star Nick Kyrgios crashed out of the 2017 Wimbledon Monday after retiring hurt in the first round against Frenchman Pierre-Hugues Herbert. Kyrgios, the 20th seed, was trailing by two sets when he called on the physiotherapist to assess persistent hip pain. Pierre-Hugues Herbert won the match 6-3 6-4.

Kyrgios has been dealing with a persistent left hip injury since ever since he pushed Roger Federer to a classic five-setter at the Miami Open semi-final in the first week of April. He also had to deal with a shoulder injury for several months and failed to exude much hope in the lead-up to the Wimbledon after dropping out in his first round match at the Queen's Club tournament in London this month.

The 22-year-old has had an impressive run at the grass-courts of the All-England Tennis Club in recent years. In 2014, he shocked the tennis world by upsetting Rafael Nadal 7-6, 5-7, 7-6, 6-3 in the quarter-finals. A year later, he pushed French veteran Richard Gasquet to four sets in a hard-fought match in the Round of 16. Last year, the young Aussie lost to eventual winner Andy Murray in the fourth round.

Nick Kyrgios may undergo hip surgery soon

Kyrgios aggravated the hip injury in a fall at the Queen's Club back in June. After rating himself "60 percent fit for the Wimbledon," Kyrgios said he would consider a hip surgery in the near future. "I'll be doing everything I can. I've been taking anti-inflammatories, doing an hour-and-a-half of rehab every day, getting treatment. But there's only so much treatment I can do with type of injury. It needs time to rest."

According to The Daily Mail, Kyrgios' serve "kept him in contention (Monday) until a double fault gave Herbert a break for 5-3 in the opening set. When Kyrgios was broken again in the seventh game of the second, he appeared to be in tears while he sat on his chair at the changeover before walking back on court shaking his head. The Australian called the trainer after Herbert won the second set to lead 6-3 6-4 before deciding he could not continue."

The 2017 Wimbledon continues Monday as World No. 1 Andy Murray and World No. 2 Rafael Nadal begin their campaigns with first-round matches against Alexander Bublik and John Millman, respectively. Roger Federer and Novak Djokovic, the other members of the Big 4, will be seen in action on Tuesday.
