Sixth-seeded Vasek Pospisil of Canada beat Dusan Lajovic of Serbia, 6-4, 7-5 in the first round of the Topshelf Open, a grass-court warm-up ahead of Wimbledon, in ‘s-Hertogenbosch, Netherlands, on Monday.
Pospisil, from Vernon. B.C., won 72 per cent of his service points and broke Lajovic twice to win the rain-delayed match in 86 minutes.
In other first round men's matches, fifth-seeded Dmitry Tursunov of Russia beat Bradley Klahn of the United States, 6-3, 7-6 (3).
Tursunov had little trouble in the first set, but each player had a break in the second to set up the tiebreaker which Tursunov won easily.
Top-seeded David Ferrer, who lost to Rafael Nadal in last year's French Open final, withdrew without playing due to stomach problems and warned he might not play at Wimbledon.
"I'm not sure if I can play at Wimbledon," Ferrer said, adding he came down with flu after Roland Garros.
"I'm going to talk with my doctor in Valencia tomorrow and see. It's been 10 days now and that's just too long for this problem."
The men's event includes defending champion Nicolas Mahut of France while French Open finalist Simona Halep is the top-seeded player in the women's tournament.
Eugenie Bouchard of Westmount, Que., is seeded third in the women's draw.
Wild-card entry Michaella Krajicek had two victories of a sort on Monday. First, she beat Jana Cepelova 6-3, 4-6, 6-1.
Then her boyfriend, German doubles player Martin Emmrich, overcame an early set of nerves and proposed to her on centre court.
With a shaky voice he called her "Bambi," got down on one knee and asked, "Will you marry me?"
The 25-year-old Krajicek, who had been standing covering her mouth in shock, giggled and agreed. They plan to compete in the mixed doubles at Wimbledon.
