AUCKLAND - Top seed Sabine Lisicki moved swiftly into the second round of the Auckland Classic with a 6-4, 6-4 victory over the French wildcard Virginnie Razzano on Monday. But the German, the world number 15, had problems with her serve that will be of concern as she builds up to the Australian Open, managing a 41 percent first-serve success rate in the first set before improving in the second.

The only other seed in action in Auckland on the opening day saw the fourth-seeded Flavia Pennetta survive a tense encounter with Romanian Sorana Cirstea to squeeze into the second round with a 6-4, 7-6 (7/5) victory.

Pennetta dropped her serve early in the first set before fighting back with two breaks of her own, and in the second set she trailed 1-3 in the tie break before producing a strong finish. “I have to be proud of this match,” Pennetta said. “For the first match of the year you don’t have a lot of confidence and you just have to try to play your tennis.”

Pennetta meets Elena Baltacha in the second round after the Briton beat New Zealand wildcard Sacha Jones 6-2, 4-6, 6-3 in the Kiwi’s final tournament before switching her allegiance to Australia. Jones qualifies to represent Australia, where her father was born, and declared recently she believed she will receive better opportunities to develop her game there.

In other opening-day matches, American Christina McHale defeated Alexandra Dulgheru of Romania 6-2, 6-3 and Italy’s Sara Errani thrashed Johanna Larsson from Sweden 6-1, 6-1.
