“I’ve worked with Todd on and off for many years and he has helped me immensely,” Kyrgios said on his website. “I am very grateful for everything Todd has taught me and helped me with, especially during the last year.”

“I will work closely with my team and Tennis Australia through Wimbledon and we will regroup after the tournament in order to figure out the best plan for the future," he said. "For now my focus is on the 2015 Wimbledon Championships and with that in mind I will not be making any further comments on this matter."

The 20-year-old has had a difficult spring, going 3-5 after his headline-grabbing upset of Roger Federer at Madrid in May. After withdrawing from Stuttgart, he lost his only grass-court warm-up match with Stan Wawrinka at Queen’s, falling 6-3, 6-4 in just 49 minutes.

Despite recent troubles, Kyrgios is the youngest player inside the ATP’s Top 30 and has reached quarterfinals in two of his last four majors.
