Forty-one-year-old Kimiko Date-Krumm became the oldest WTA player to win a doubles title besides Martina Navratilova when she and Zhang Shuai edged No.1 seeds Vania King and Yaroslava Shvedova, 75 36 119, in Sunday's Osaka final.

Date-Krumm has made quite a few additions to her resume since returning to the WTA in 2008 after more than a decade away. Among those is the greatest-ever gap between singles titles, as 13 years and one month passed between her victory at Tokyo [Japan Open] in 1996 and Seoul in 2009. Her gap between doubles titles is even longer, as 15 years and six months passed between her victory at Tokyo in 1996 and Osaka in 2011.

Here is the list of all 40+ doubles title winners in the Open Era:

Notes: Age reflects how old player was on first day of event they won ... Navratilova's record-breaker at '06 Montréal came alongside Nadia Petrova ... King is the oldest Open Era singles titlist, having won Birmingham in '83 when she was 39 years and seven months, with Date-Krumm becoming second-oldest when she won Seoul in '09 at 38 years and 11 months ... The oldest ATP singles titlist is Pancho Gonzales, who was 43 years and nine months when he won Des Moines in '72.
