TOKYO — Table tennis chiefs were encouraged by what they described as a “positive” response to their pitch for an extra gold medal at the 2020 Tokyo Olympics, the International Table Tennis Federation (ITTF) said Monday. ITTF President Thomas Weikert met Tokyo organizing committee chief Yoshiro Mori in Japan and outlined his proposal to add mixed doubles to the existing four medal events, men's and women's singles and the team tournaments. In order not to inflate the number of athletes at the Games, the ITTF is proposing that only players qualified to play in the other events will be able to take part in the mixed doubles. — Reuters
