TOKYO (AFP) - Japanese media on Monday hailed veteran Kimiko Date-Krumm's first tournament victory in 13 years, which made her the oldest winner of a WTA event since Billie Jean King in 1983. Date-Krumm, who celebrated her 39th birthday on Monday, won the Korean Open on Sunday in Seoul when she upset Spain's second seed Anabel Medina Garrigues 6-3, 6-3. The mass-circulation Yomiuri Shimbun wrote in a headline, "A series of fine shots makes up for a lack of speed" and the influential daily Asahi Shimbun praised her "fighting spirit". It was Date-Krumm's eighth career title and the first since her comeback in 2008. Her last title was the Toshiba Classic in San Diego in August 1996. "Date-Krumm has adapted herself to contemporary tennis, which has advanced in speed and power since the 1990s when she made a spectacular showing," Kyodo News said. Date-Krumm reached world number four in 1995 before retiring a year later after finding the pressure of life on tour too much. She married German racing driver Michael Krumm in 2001. She was due to face Canada's Aleksandra Wozniak in the first round of the two-million-dollar Pan Pacific Open in Tokyo later on Monday. Her world ranking rose to 100th from 155th after the Korean Open title.
