Brussels, Belgium -- (Sports Network) - Belgian Justine Henin, the world's top- ranked women's tennis player, will reportedly announce her retirement on Wednesday.

The newspaper Het Nieuwsblad reported that the 25-year-old Henin, who has a 16-4 mark this year, will call it quits at a news conference. Her mark this year includes a third-round exit at the Berlin Open last week. Henin withdrew from this week's Italian Open, citing fatigue.

A four-time French Open winner, Henin has captured seven Grand Slam titles and has 41 overall for her career. She first rose to No. 1 on October 20, 2003, and this week marks her 61st consecutive at the top of the rankings and 117th overall.

The winner of the last three championships at Roland Garros, Henin has two titles this year - in Sydney and Antwerp. She was ousted by Russian Maria Sharapova in the quarterfinals at the Australian Open, the first Grand Slam event of 2008.

Henin would be the second Belgian women's tennis star to retire in as many years after Kim Clijsters called it quits in 2007.
