As others have said
That he didn't aim at her doesn't matter. The rukes are clear, and exist for very good reasons. He defaulted. His Seeding can't negate that! And his attitude afterwards was revolting!
He had already earned a soft warning, a cough I believe, when he whacked a ball at the hoarding. That's a temper thing and is officaily proscribed - abuse of the ball is ANYTHNG outside of actual play.
When you clear a ball it is supposed to be done carefully, eye contact with the intended recipient, into the space the runner/ball boy/girl is heading into. Happens every match, every training session ever undertaken!
Line judges do not gather up loose balls!
As for his misogyny ask him where the invitations for female players to join to his new Tennis association went!
Female athletes train the same as the men. In most tournaments EVERYONE PLAYS THREE!!! It's just the slams that have the discrepency. That was to show off the male prowess, making the Slams what they are - prestigious, hard, worth winning!
Slam tennis is very old fashioned and hasn't changed its set up. That's as much becasue of time constraints as anything else - that's being kind and not accusing them of the same rank misogyny their Victorian predecessors had when they set those rules!
But women have played five sets for over 100 years! Yes! Go figure! For example before the U.S. National Championships became the U.S. Open women played 5 sets in the final. That was in 1890 ish with full length skirts and petticoats! FFS!
That was part of Billie Jean Kings fight for parity! Men were payed more, justified by playing more. Women didn't make that choice, men running tennis did! WOmen like BJK fought it tooth and nail! As many other women fought other pay gaps!
Hell, players actually voted to play 6 sets in the mid 1970s. But the organisers chose not to hear that! Ask Chris Evert and the Women's Tennis Association. 3 sets was not their choice! Ask Martina how she felt at not being able to show the same prowess, skill and fitness levels as her male counterparts. How she felt when that restriction was temporarily lifted an she found that her specific training had negative impact on her abilty to play over 5 sets (granted Graf, Seles and Sabatini were blood magnificent)
And back to 3 sets they went!
Nope! I do not like tennis... I.....
