The formerly top-ranked Sharapova, who has been hampered by an injury to her right elbow this season, converted only four of 22 break points. Anastasia Rodionova of Australia also advanced to the second round with a 2-6, 6-3, 7-5 win over Ayumi Morita of Japan. Bondarenko, Dulgheru thru In Poland, sixth-seeded Alona Bondarenko beat Roberta Vinci of Italy 6-3, 6-1 Monday to advance to the second round of the rain-disrupted Warsaw Open. Bondarenko's match was delayed for several hours by heavy rainfall, and the Ukrainian's sister Katerina Bondarenko then lost 6-3, 6-1 to defending champion Alexandra Dulgheru of Romania in the only other completed match of the day. Kubot beats Mina In France, eighth-seeded Lukasz Kubot of Poland beat Gianni Mina of France 7-5, 6-4 to reach the second round of the Open de Nice Monday.

Also in the Red Group, the Czech Republic clinched a win over Spain after Tomas Berdych outlasted Nicolas Almagro 6-7 (4), 6-4, 6-3 to give his team a 2-0 lead ahead of the doubles.

In the Blue Group, France defeated Germany 2-1 after Jeremy Chardy and Nicolas Mahut beat Christopher Kas and Philipp Kohlschreiber 6-3, 3-6, 10-5 in the doubles. Argentina beat Serbia after Juan Monaco rallied for a 1-6, 6-3, 7-6 (3) win over Victor Troicki for a 2-0 lead after the singles.
