Renata slipped off-camera and injured her knee badly on the 1st point of the match. Unfortunate. Loud screams in pain and she was crying a lot, had her knee taped after the MTO. Might be a very big injury.
There was a WTA final in 1996 that finished 0:0 RET before finishing the first game. Paulus was a former top 10 WTA and Cecchini a former top 15 WTADoes anyone know, or care to research, how often this has happened over the last X years - a match in which one player retires after the first point? Or when it happened most recently?
(Since this tournament is WTA125, the answer could be about tournaments of that level as well as higher levels; but the answer only for strictly higher tournament levels, so-called 'real' WTA tournaments, would also be interesting.)
