(CNN) -- Last year's finalist Dinara Safina has been knocked out of the French Open in the first round by unseeded 39-year-old Kimiko Date Krumm of Japan.
Russian former world number one Safina, the ninth seed, lost 3-6, 6-4, 7-5 in the biggest shock of the tournament so far.
Date Krumm, who ended a 12-year retirement from the sport in 2009, had not played at the French Open since 1996.
She becomes the second oldest women to win a match at Roland Garros in the Open era after Virginia Wade in 1985.
Meanwhile, four-time champion Justine Henin beat Tsvetana Pironkova of Bulgaria 6-4 6-3 to reach the second round.
Belgium's Henin is competing at the clay court grand slam or the first time since 2007 after coming out of retirement in January. Link
