TOKYO (AP) Third-seeded Victoria Azarenka made short work of Irina-Camelia Begu on Tuesday, beating the Romanian 6-1, 6-3 in the second round of the Pan Pacific Open.

Azarenka, winner of two WTA Tour titles this season, closed out the match 1 hour, 15 minutes under clear skies at Ariake Colosseum, a day after rain forced the closure of the roof and disrupted play on the outer courts for several hours.

Begu was unable to break the Belarussian a single time during the contest, despite having nine chances. Azarenka won 72 percent of her first serves in the match.

In other second-round matches, ninth seed Agnieskza Radwanska of Poland downed qualifier Angelique Kerber of Germany 3-6, 6-3, 6-3, 12th-seeded Ana Ivanovic of Serbia topped Laura Robson of Britain 7-5, 6-4, and 13th seed Julia Goerges of Germany beat Greta Arn of Hungary, 6-2, 6-1.

Shuai Peng of China beat American qualifier Jill Craybas 6-2, 6-0 in the first round, while unseeded American Christina McHale defeated Tamira Paszek of Austria, 7-6 (1), 6-3. Another American, Coco Vandeweghe, won her rain-delayed match that started on Monday over Jie Zheng of China 7-6 (4), 4-6, 6-2.

After a short rest, Vandeweghe will again take the court Tuesday for a second-round meeting with Kaia Kanepi of Estonia.

Top-seeded Caroline Wozniacki of Denmark will take on Jarmila Gajdosova of Australia in a second-round match later Tuesday, while U.S. Open champion Samantha Stosur of Australia, the sixth seed, will face Russia's Maria Kirilenko.
