LONDON — Milos Raonic’s big serve powered him to another victory at Wimbledon.
The No. 13 seed advanced to the third round of the grass-court Grand Slam on Wednesday with a 7-6 (4), 7-6 (4), 7-6 (4) victory over unseeded Australian John Millman.
Raonic had just four break-point opportunities in the match, winning one.
But Millman did next to nothing against Raonic’s serve, converting on one-of-two break-point chances. Raonic had 34 aces, compared to only three for Millman.
The 27-year-old from Thornhill, Ont., leads the ATP Tour in the past year with wins in 73.7 per cent of his tiebreaks, a trend Raonic continued in his second-round victory.
A return to Wimbledon for the 2016 finalist seems to have given Raonic a boost. He lost in the first round of the Australian Open this year and missed the French Open with an injury, one of several health setbacks he has suffered in the past few years.
Raonic avoided a confrontation with a seeded player in the third round as qualifier Dennis Novak of Austria upset No. 17 Lucas Paille of France 6-4, 6-2, 6-7 (8), 3-6, 6-2 on Wednesday.
Novak, ranked 171st in the world, defeated Canadian Peter Polansky in the first round. Novak and Raonic will be squaring off for the first time.
Later Wednesday, Gabriela Dabrowski of Ottawa and partner Yifan Xu of China, the sixth seeds in the women’s doubles draw, open their tournament against American Alison Riske and Olga Savchuk of Ukraine.
Eugenie Bouchard of Westmount, Que., and No. 26 seed Denis Shapovalov of Richmond Hill, Ont., are expected to play second-round matches on Thursday.
