MALLORCA, Spain — Garbine Muguruza lost her first match since winning the French Open, falling to Kirsten Flipkens of Belgium 6-3, 6-4 in the first round of the Mallorca Open on Tuesday.

The second-ranked Muguruza had a 2-1 record against Flipkens, but the Belgian won their only previous match on grass three years ago en route to the Den Bosch final.

Muguruza had two break points for 4-3 in the first set but Flipkens held, and broke Muguruza's serve in the next game. She won the set when Muguruza hit a backhand into the net. In the second, Flipkens made the decisive break at 3-3.

Muguruza was the highest-ranked opponent she's beaten.

Two other seeded players also lost: No. 4 Kristina Mladenovic of France to former Wimbledon finalist Sabine Lisicki 6-4, 6-4, and No. 5 Yulia Putintseva of Kazakhstan to Sorana Cirstea of Romania 6-3, 6-2. Cirstea saved all four break points she faced.

Second-seeded Jelena Jankovic improved her win-loss record to only 8-13 this year after beating Ana Konjuh of Croatia 7-5, 6-3.

Another player in need of a good run was former Wimbledon finalist Eugenie Bouchard of Canada. She started the year with finals in Hobart and Kuala Lumpur but has won only half of her matches since February. She defeated Danka Kovinic of Montenegro 6-3, 7-5.

Third-seeded Ana Ivanovic struggled to get past Pauline Parmentier 6-4, 6-4. Ivanovic saved 10 of 13 break points, and managed to convert all five against the Frenchwoman.
