I love tennis but some of these rules.... there's no need for linesman and chair umpires to mess up calls and ruin tournaments anymore. You would think one of the more popular 500 events would have Hawkeye doing the match. Do people realize how insane the challenge system is in tennis? Ur serving down break point and miss your first serve, your "conservative" 2nd serve lol gets destroyed and appears to be just long of the baseline and u manage to get it back over the net. U challenging or trying to continue the rally? Ur supposed to make that decision basically instantly so not only are u playing but ur trying to do Hawkeyes job on top of it! There's just no excuse for this to happen, there shouldn't be a line judge to yell at. The only reason there's still a chair umpire is to tell the players when the point is over. Besides that, tennis as a sport needs to realize some of their rules regarding "code and conduct" are an absolute joke and are hurting the sport. Should he have got in that guy's face? No. Did he have a right to be very angry and act like a human being who got screwed the first game of the match with multiple break points? Absolutely. U got players enduring an 11 month season, working their asses off everyday to make money and get points and u expect them to act like robots when u screw them over? I love tennis. It's great. But it could be even better with some simple rule changes and making Hawkeye mandatory everywhere. And while we're at it can we plz just get rid of these stupid ass net rules? If ur serving it's fine as long as it still lands in but when ur in a rally and it dribbles over, that's OK? Why are we rewarding the player thar should be losing the point? Any ball that hits the net, the point should be over. 100% fair. And it's something Hawkeye can also do, pretty sure neway.
