Japanese veteran Kimiko Date-Krumm and Vania King of the United States won their opening matches at the WTA Tour's Indian Wells tournament on Wednesday.

Date-Krumm breezed past Pauline Parmentier of France 6-1, 6-3 and American Vania King surprised world No. 31 Sara Errani of Italy 7-6(3), 6-4 as the women's draw of the WTA and ATP Masters joint tournament got underway.

At age 41, Date-Krumm is the oldest player in the women's field and was giving away 15 years to the 26-year-old Parmentier on Wednesday.

Date-Krumm won 79 percent of her first-serve points and 57 of 92 total points in the one-hour match.

Parmentier had four aces but also committed four double faults and won just 35 percent of her first-serve points.
