There they go again.
For the second consecutive day at the U.S. Open — or maybe it was the fifth, or the 10th, depending on when the counting started — a teenage woman did the thing she was not supposed to do.
Just as Leylah Fernandez of Canada did on Tuesday, Emma Raducanu of Britain bulldozed her way through a player who had every right to believe the day would belong to her, disposing of 11th-seeded Belinda Bencic of Switzerland, 6-3, 6-4, in 82 minutes, and giving the U.S. Open two semifinalists who are unable to celebrate their success legally with an alcoholic beverage.
