LONDON, June 26 (UPI) -- Top 10 seeds Victoria Azarenka, Petra Kvitova, Serena Williams and Marion Bartoli all had straight-set wins Tuesday in their first-round matches at Wimbledon.

Azarenka, the No. 2 seed and Australian Open champion, defeated Irina Falconi 6-1, 6-4. Azarenka, who had nine double faults, dropped serve three times while posting six breaks against Falconi.

Kvitova, seeded fourth after winning at Wimbledon in 2011, overcame an early break for a 6-4, 6-4 win over Akgul Amanmuradova. The first service game break was the only one against Kvitova on the day as she ended up winning more than two-thirds of the points on serve.

The sixth-seeded Williams had just 12 unforced errors in a 6-2, 6-4 decision over Barbora Zahlavova Strycova. She piled up six breaks while winning 58 percent of the points off Zahlavova Strycova's serves.

Bartoli backed up her No. 9 seeding in a 6-2, 6-4 victory over Casey Dellacqua. Bartoli didn't lose her serve in the match.

Several matches were unable to be completed Tuesday because of a late rain storm. Those who will finish their first-round play Wednesday include former world No. 1 Caroline Wozniacki, the No. 7 seed, and French Open runner-up Sara Errani, who is seeded 10th.
