I still don't understand why women only play 3 games (and often 2). Okay, from a fitness and stamina p.o.v., there may be justification, but if you've progressed to the semi's and finals you've proved your worth, and should play up to the 5 games in these 2 events, just like the men.
Women's semi's and finals is so frequently a dull wash-out and I can't understand anyone wanting to pay to watch what is frequently a 1 hour match.
Re. Osaka, if she felt that strongly, why on Earth did she not take it up with the authorities prior to the tournament rather than suck it 'n' see, incurring a $15K fine (?) and a great deal of controversy. After all, I believe she's a 4 times champion, so hardly a newcomer at 23.
Maybe these rules are anachronistic and need adaptation, and this fiasco will certainly invite discussion and introspection among the tennis fraternity. Who knows, the publicity she has engendered may have been worth the fine and losing the chance of another feather in her cap; there may even have been an element of planning, as I think her actions may be unprecedented.
