Justine Henin again proved too strong for Elena Dementieva at the Sony Ericsson Open in Miami.
She knocked the fifth seed out of the event at the second-round stage with a comprehensive 6-3 6-2 win.
Henin, who is a wildcard in Miami as she continues her comeback, beat Dementieva in the second round of this year’s Australian Open.
While that was a hard-fought encounter, the Belgian coming through 7-5 7-6 (8/6), this was a far more one-sided affair.
Henin did not even concede a break point in the first set and broke three times in the second to win in a little under 90 minutes.
Henin’s compatriot Kim Clijsters, seeded 14 here, had an even easier day’s work, brushing aside Petra Kvitova of the Czech Republic 6-1 6-1 in 52 minutes.
Second seed Caroline Wozniacki was forced to work hard by qualifier Tsvetana Pironkova, before prevailing 3-6 6-3 6-4.
Ninth seed Samantha Stosur was also forced to come from a set down as she beet Carla Suarez Navarro 4-6 7-5 6-2.
Seventh seed Jelena Jankovic emerged victorious against Ukrainian qualifier Mariya Koryttseva.
The 25-year-old Serbian, ranked eighth in the world, claimed six of eight break point chances to win 6-4 6-0 in an hour and a half as she looked to claim back-to-back tournament triumphs after winning in Indian Wells.
Fourth seed Victoria Azarenka cruised past Alexandra Dulgheru of Romania 6-3 6-2 in one hour and 12 minutes, claiming four of six break-point opportunities in the match.
There were straight-sets wins for seeds Vera Zvonareva, Francesca Schiavone, Shahar Peer and Elena Vesnina.
Zheng Jie was less fortunate, with the 20th seed from China losing 6-4 6-2 to Virginie Razzano of France.
Lucie Safarova saw off another seeded opponent Maria Jose Martinez Sanchez, with the Czech winning the match 6-4 6-7 (3-7) 6-2, while 24th seed Alisa Kleybanova slipped 6-4 7-5 to Sara Errani.
Dominika Cibulkova, seeded 26th, was comfortable in a 6-0 6-2 victory over Sweden’s Sofia Arvidsson while 32nd seed Maria Kirilenko of Russia fought back from a set down to beat Hungary’s Melinda Czink.
Another Russian, Anastasia Pavlyuchenkova, knocked out Tamira Paszek 7-6 (7-4) 4-6 6-3.
