Pennetta, Petrova through to second round

As the second day at the Commonwealth Bank Tennis Classic ended, three seeds advanced to the next round, and one seed was sent flying home.

No. 3 seed Flavia Pennetta, the first seed through, took nearly two hours to oust American Vania King in three sets, 76(7) 61.

"It was tough at the beginning getting used to the humidity and different rhythm from New York, that's why the first set was closer," Pennetta said after her 76(7) 61 win. "Once I settled down and played my game, her level dropped and it was much easier after that. I had a great time in New York and I've had a great season but I heard so many nice things about Bali I had to come. I would really like to do well this week."

No. 4 seed Nadia Petrova, who was the loser in the US Open against Pennetta, had a good opening match, defeating Aiko Morigami in straight sets, 63 61.

"I was very solid and did the right tactics," said Petrova, who won the Tier III event at Cincinnati last month and also reached the final at Eastbourne in June. "I have been working really hard since April with my new coach and have improved a lot physically. That's helping me move better on the court and I'm very happy with the way things are going."

Next up for Petrova is Tathiana Garbin of Italy, who had too much experience in the crunch for Hungary's Melinda Czink, winning 62 76(3). But the Italian veteran soon found herself on the receiving end of a warning from Petrova: "I'll be looking for some revenge after she ruined my New Year's Eve on the Gold Coast with a three and a half hour match," the Russian joked. "I hope it's quicker this time because in the humidity I think we will both be dead!"
