The whole match only LSD got called out and it was quite funny when the umpire was right and the look of LSD face after the review is hilarious. I think for him it was twice and the umpire was right for both times. I don’t think LJK did any illegal serving or anything. I can’t remember if the umpire called out LJK for any illegal serves, I don’t think so.
On this subject, here's something to try.
Film your serve practice from the perspective of the opposing player and do 100 pendulum/rev pendulum serves.
I can guarantee that more of them than you think will fall into the category of questionable, for several reasons.
Point being, sometimes a serve is not correct but it's not because a player wanted to deliberately cheat.
And, because the culture up to now has been to just let everything go, players are sometimes genuinely surprised when they're called and found to be in the wrong.
Very glad the umpire caught him twice, it's the only way to force players to do it correctly going fwd.
But I think it's going to take a while because unfortunately not all the umpires are as good as he was....
