Ranked No.175, Vickery took her spot in the main draw after Beatriz Haddad Maia withdrew with a hand injury. 

"Honestly, I was getting ready to leave tomorrow, I already had my flight," Vickery said. "I was ready to go home. I came this morning and, unfortunately, Bia also hurt herself, and I wish her a speedy recovery. Sometimes that happens, some weeks on the tour."

Vickery trailed 5-2 in the first set before mounting a comeback to force a tiebreak. There, Vickery saved two set points before taking it 7-6(7).

After already calling a medical timeout and receiving treatment earlier in the set, Çollins could not continue. 

In as a lucky loser, the 28-year-old American will face her compatriot, Caroline Dolehide next. Dolehide won her opener over No.43 Peyton Stearns, winning 6-7(1), 7-6(5), 7-6(2).
