Slovenia’s world No.100 Kaja Juvan scored the biggest win of her career with a 7-6(6) 6-1 upset of second seed Aryna Sabalenka to move into the quarterfinals of the WTA 500 tournament.
The 21-year-old Juvan recovered from a break down twice in the first set, saved a set point in the tiebreak, and raced through the second set as Sabalenka lost the match with 18 double faults in 89 minutes.
