Daniilidou is going through a year of consolidation after her remarkable breakthrough last season.
The 20-year-old Greek was virtually unknown before last year but, in June, collected her first WTA Tour title with consecutive wins over Amelie Mauresmo, Justine Henin-Hardenne and Elena Dementieva on 's-Hertogenbosch's grass.
She followed that by producing her best performance in a Grand Slam tournament at Wimbledon, where she was eventually halted in the fourth round by Jennifer Capriati.
Daniilidou continued her progress this year by winning the first tournament of the season in Auckland, saving two match points in the final to seal her second career title.
She then equalled her best Grand Slam finish at the Australian Open, but has since been in disappointing form.
The Greek slipped out of the top 20 with a second-round defeat at Wimbledon to Mary Pierce and has struggled on North America's hard courts.
