This was worse than what happened at Wimbledon
because Serena hit an obvious winner, the linesperson called it IN!!, and the chair simply gave the point to Jenn without even making an overrule.
At Wimbly, the ump BY MISTAKE awarded a phantom point to Sprem, but in this case, the ump took a point away from one player and gave it to the other. It should have been corrected on the spot.
