Question: Did Robin White and Margaret Court play professional tennis? 
Context: The 1969 British Hard Court Championships was a combined men's and women's tennis tournament played on outdoor clay courts at The West Hants Club in Bournemouth in England.  It was the 40th edition of the tournament and the second edition in the Open Era of tennis.  The tournament was held from 28 April through 3 May 1969.  John Newcombe, seeded first, and Margaret Court won the first open singles titles while the men's team of Bob Hewitt and Frew McMillan and the women's team of Margaret Court and Judy Tegart won the doubles titles.  The poor state of the courts led to a protest by a number of players.  The tournament made a financial loss due to higher expenses compared to the previous edition and poor weather during the final two days. While many mixed doubles tennis players have won at least one title in each of the four Majors, a career slam, only one mixed doubles team has won the coveted "Grand Slam", all four titles in a single calendar year, Margaret Court and Ken Fletcher in 1963.  Margaret Court and Owen Davidson also won an individual "Grand Slam" with different partners. The 1992 Nutri-Metics Bendon Classic was a women's tennis tournament played on outdoor hard courts at the ASB Tennis Centre in Auckland in New Zealand that was part of Tier V of the 1992 WTA Tour.

Teeguarden was voted the "Most Watchable Player" based on play and appearance by a group of Madison Avenue advertising executives or "Mad Men" while playing at the US Open.  Teeguarden played in 19 consecutive US Opens, holding the record until Chris Evert played in 20.
