Coleman Wong Chak-lam of Hong Kong started in style in the Wimbledon boys’ singles on Sunday with a straight-sets victory in his first-round match. Wong saw off Jonah Braswell of the United States 7-6, 6-2, struggling initially before taking charge of the match. The 18-year-old, already twice a junior grand-slam title winner in doubles, found himself a break down early in the first set on court 15, trailing 3-1, but battled back to win it in a tiebreak. Wong negotiated the second set in far more straightforward style, winning it 6-2 to finish the job in an hour and 31 minutes. Next up for the Hongkonger will be No 9 seed Dino Prizmic of Croatia, who on Sunday defeated Tanapatt Nirundorn of Thailand. Who is 17-year-old Hong Kong tennis prodigy Coleman Wong? Wong, who has spent time training in Spain at the Rafa Nadal Academy, has yet to go deep into a grand slam event in singles, but he made history last year when he became only the second Hong Kong player to win a grand slam title, partnering France’s Max Westphal to the boys’ doubles title at the US Open. He followed that by winning the next slam, too, taking the boys’ doubles crown at the Australian Open in January alongside American partner Bruno Kuzuhara.
