Seriously, every match I've seen has had at least one poor call that effected the outcome of the match and multiple other atrocious calls. It doesn't even make sense since all the tournaments use basically the same lines people. I even saw that little asian woman who Serena tried to kill
They really need to think of installing hawkeye on every court that has it, or even better changing the rules. I think the chair umpires should have more discretion about who wins the point rather than strictly following the "replay the point" rule if the opponent gets a racket on the ball.
Tell me what you think or just gripe next time you see a bad line call at the AO
