INDIAN WELLS, Calif. (AP)—Retired stars Steffi Graf, Martina Navratilova and Lindsay Davenport are joining current women's player Justine Henin in a second match at a charity tennis exhibition to raise money for Haiti.

Roger Federer and Rafael Nadal will team with retired stars Pete Sampras and Andre Agassi in an already announced men's match during the ``Hit for Haiti'' benefit to be played March 12 at the BNP Paribas Open in Indian Wells, Calif.

Tournament director Steve Simon says he expects a minimum of $1 million to be raised for Haiti earthquake relief efforts. A similar event held during the Australian Open raised more than $600,000.
