Unforced errors sank the survival chances of Belinda Bencic on Wednesday as the Swiss fifth seed crashed out in her opening match in Charleston.
Spain’s Paola Badoso did the damage with a 6-2, 6-7(2), 6-1 win which featured two match point chances for the No. 71 in the second set.
Victory was Lyon semi-finalist Badosa’s first career defeat of a Top 20 opponent.
Bencic got off to a poor start, losing the opening game of the morning and ending the first set with 13 unforced errors.
Badosa was unable to serve out a straight-sets upset in the second set while leading 5-3 and again at 6-5 as Bencic brought her experience to bear by levelling the sets.
In the third, the Spaniard got away to a 5-0 lead and two games later advanced to the third round on her fifth match point.
I couldn’t close the match,” the winner said. “I was so, so nervous because I knew it was a big win.
“I accepted the nerves, I tried to play aggressive, tried to hit with spin – that’s what I tried the entire third set.”
Badosa now takes on US teenager Caty McNally. who laid on a 7-6(3), 2-6, 6-4 result against last week’s Miami quarter-finalist Anastasija Sevastova after nearly two and a half hours.
McNally recovered from deficits in both sets for the win.
Ninth seeded Czech Marketa Vondrousova withdrew with illness before her match.
Her opponent Kurumi Nara, a Japanese qualifier, made the most of her good fortune, defeating lucky loser Whitney Osuigwe 6-1, 6-4 for a second straight WTA-level win – her first time in four years.
