Collins saved all three break points she faced while converting five of eight break points on McNally’s serve. Anna Kalinskaya will be Collins’ next opponent. In her round-of-16 match, Kalinskaya defeated Coco Vandeweghe 6-3, 6-1 in 56 minutes.
Kalinskaya won 90% of her first-serve points, saved the lone break point she faced and converted four of five break points on the American’s serve.
