Kuznetsova was on the brink when Petkovic served at 5-4, 40-0 in the second set, but the tough minded sixth seed took advantage of her opponent's unforced errors to turn the tables.

British fourth seeded Andy Murray grabbed an easy first set win in the men's second round.

The Australian Open runnerup Murray, who edged French talent Richard Gasquet in a five-set marathon fight on Monday, met little challenge from Aargentine Juan Ignacio Chela on Wednesday, taking the opening set in 6-2. But since the rain bothered the whole competition schedule, they had to continue their duel on Thursday.

At the same time, the 13th seeded French Gael Monfils needs to make a final fight on Thursday in the deciding set against Fabio Fognini. Monfils took the first two sets, but lost the following two to the Italian. Then, they tied 5-5 in the final set.

Both Robin Soderling from Sweden and Jo-Wilfried Tsonga of France enjoyed comfortable win in the men's second round.

The 5th-seeded Soderling smashed American Taylor Dent in 6-0, 6-1, 6-1. The 8th-seeded Tsonga knocked out compatriot and friend Josselin Ouanna in 6-0, 6-1 and 6-4.

American second seed Venus Williams, who led the opening show on the center court, wasted little time to beat Spainish Arantxa Parra Santonja 6-2, 6-4.
