Japan Open: 19-year-old American Krueger through to semi-finals
The American will face the winner of the match between Japanese wildcard Mai Hontama and Dutch qualifier Arianne Hartono in the semi-final
This is the first WTA Tour level semi-final for Krueger and the sixth top 100 win of her young career. Earlier this year, the American teen had scored a win over former world No 1 Victoria Azarenka during the grass season.
The 19-year-old American defeated Ukrainian Kateryna Baindl, the No 8 seed (6-2, 6-3) and Frenchwoman Jessika Ponchet (6-4, 6-1) earlier in the week.
In the previous rounds, Kalinskaya, ranked No 92, won against German Jule Niemeier (6-4, 6-4) and Harriet Dart (7-6 (5), 6-2).
