Badosa won 6-4, 6-3 over Ashleigh Barty
in the quarterfinals of Charleston on Friday.
Badosa picked up the best win of her career as she defeated the world No. 1 in a surprisingly straightforward victory behind seven aces while also breaking serve five times. The 23-year-old Spaniard entered this event without a Top 20 win in her career, but she already has two in this tournament. Badosa will take on Veronika Kudermetova
(0-2 H2H) or Sloane Stephens
(1-0 H2H) in the semifinals.
