NEW YORK – Belgium's Elise Mertens put American wildcard Kristie Ahn’s U.S. Open run to an abrupt end on Monday, defeating her soundly 6-1 6-1 to reach the quarter-finals.
Ahn may not have gotten as much attention as fellow Americans Coco Gauff or Taylor Townsend at Flushing Meadows but she walked into Louis Armstrong Stadium with major momentum.
The 27-year-old former Stanford University player had beaten Mertens in San Jose a little over month ago and reached the fourth round without dropping a set, becoming the first Asian American woman to make the round of 16 since 2000.
But Mertens, seeded 25th, was too consistent, keeping her unforced error count low and winning 79% of points on first serve.
Mertens will face the winner of the late match between American Taylor Townsend and Canada’s Bianca Andreescu.
