Casey Dellacqua has set up a quarter-final meeting with Romanian Simona Halep after a fourth round walkover against Lauren Davis at the Indian Wells Masters tennis tournament.

Davis’s stomach virus ensured the Australian won through her sixth consecutive match at Indian Wells after the world No.78 had also had two victories in qualifying.

It continues a good start to the year for the 29 year-old who reached the fourth round of the Australian Open in January.

She’ll have her hands full with Halep though, the world No.7 the most improved player on tour during 2013.

On Tuesday Halep eased to a 6-2 1-6 6-4 win over 2014 Australian Open finalist Eugenie Bouchard.

Meanwhile Jelena Jankovic routed Caroline Wozniacki 6-3 6-1 to reach the quarterfinals.

Jankovic next plays second-seeded Agnieszka Radwanska or 22nd-seeded Alize Cornet, who meet late Tuesday in a fourth-round match.

Jankovic made the quarterfinals for the first time since winning the Indian Wells title in 2010, when she beat Wozniacki. The Dane won the title in 2011 and lost to Maria Sharapova in last year’s final.

But she offered little resistance against Jankovic, who raced to 5-0 in the second set before Wozniacki held at 40-love to avoid being shut out.
