Kaia Kanepi advances in Stuttgart as former No. 1 Caroline Wozniacki pulls out

STUTTGART, Germany -- Kaia Kanepi of Estonia defeated lucky loser Johanna Konta of Britain 7-6 (4), 6-4 to book her place in the second round of the Porsche Grand Prix on Monday.

Konta lost her qualifier to Italy's Giola Barbieri but was given a place in the first round when former world no. 1 Caroline Wozniacki pulled out of the tournament with a left wrist injury.

Dominika Cibulkova of Slovakia also withdrew with an Achilles injury, a day after losing the Malaysian Open final.

Among Tuesday's matches are Maria Sharapova vs. Lucie Safarova, and Jelena Jankovic against Germany's Mona Barthel, who replaced Cibulkova.
