PARIS – Christina McHale of the United States broke Pauline Parmentier's serve four times in a 6-4, 6-1 win in the first round of the Open GDF Suez on Monday.
McHale has a second-round match against No. 3 Marion Bartoli of France.
In other matches, eighth-seeded Klara Zakopalova of the Czech Republic beat Anabel Medina Garrigues 2-6, 7-5, 6-0. Zakopalova needed 2 hours, 17 minutes to get the better of the Spaniard, who had won seven of their previous 10 matches.
Garrigues did not face a break point in the first set and broke Zakopalova twice. But Zakopalova broke her twice in the second and then cruised in the third. She next faces either Carla Suarez Navarro of Spain or a qualifier in the second round.
Mona Barthel of Germany also advanced with a 7-6 (1), 6-0 win against Urszula Radwanska of Poland and next faces either fifth-seeded Roberta Vinci of Italy or Simona Halep of Romania.
