NEW YORK—Former U.S. Open champion Bianca Andreescu fired off 21 winners to make quick work of Belgian Greet Minnen 6–1, 6–2 in the third round of the tournament on Saturday.
The 21-year-old Canadian won nearly all of her first-serve points in the first set on Louis Armstrong Stadium with just four unforced errors, two years after she hoisted the trophy.
