A pair of qualifiers got big wins on Wednesday in The Shipyard Cup at the Van Der Meer Shipyard Racquet Club on Hilton Head Island.
The women's $10,000 ITF Pro Series event was in its second day of main draw play.
Qualifier Melissa Kopinski dropped third-seeded Lauren Herring, 6-3, 6-2, in the day's biggest upset.
Fellow qualifier Alexa Bortles knocked off No. 5 seed Anna Brogan 7-6(5), 6-7(6), 6-4.
Top-seeded Alexa Graham, ranked 536th in the world, defeated wild-card entrant Jaquelline Pelletier of Hilton Head, 6-1, 6-0.
The 17-year-old Graham, who reached the second round in last year's event, has reached the final in two ITF $10,000 tournaments this year.
Graham will face qualifier Aline Berkenbock, a 5-7, 6-3, 6-2 winner over Katelyn Stokes, in the day's second match Thursday on Court 7.
