Brussels, Belgium, 19 May 2011 | AP

Australia’s Casey Dellacqua put up a fight but ultimately lost to Ayumi Morita of Japan in the second round of the Brussels Open on Wednesday.

The 26-year-old from Perth went down in a three-setter 1-6 6-0 7-5.

Morita will now meet French Open champion Francesca Schiavone in the quarter-finals after the Italian veteran beat American lucky loser Irina Falconi 6-4 6-4.

Sweden’s Sofia Arvidsson upset fourth-seeded Jelena Jankovic of Serbia 3-6 6-3 6-3 to reach the quarters.

It was the latest setback for Jankovic on clay this spring. She has failed to progress beyond the second round of three of the four tournaments she has played on the surface. Last week, she reached the quarter-finals in Rome for her best clay-court result this year.

Jankovic has reached the semi-finals of Roland Garros three of the last four years.

World No.1 Caroline Wozniacki opened her bid for the inaugural Brussels Open title by beating American Varvara Lepchenko 6-4 7-6 (7-5).

Wozniacki will now face sixth-seeded Yanina Wickmayer who edged 17-year-old qualifier Alison Van Uytvanck 7-6 (7-2) 6-4 in the all-Belgian battle.

Second-seeded Vera Zvonareva survived an early scare to beat Kazakh Galina Voskoboeva 2-6 6-4 6-3 and advance.

Eighth-seeded Peng Shuai of China joined the Russian in the last eight, beating qualifier Abigail Spears of the United States 6-2 6-0.

The clay-court tournament is the last preparation event for the French Open, which starts on Sunday.
