Carl flips the script and interviews Jeff this week on his recent efforts to add pre-Open Era women's tennis data to Tennis Abstract. High-level tennis did not begin in 1968 with the introduction of Open tennis, but official statistical records often give the mistaken impression that it did. We talk about the existing state of the data, the players whose reputations rest heavily on pre-Open Era accomplishments, and the value of simply getting historical records into an accessible format. We also cover two very different #1s, Althea Gibson and Margaret Court, and dip into what people get right and wrong in the Serena-vs-Court debate.
