Shelby Rogers has been on the verge of a major moment in her young professional tennis career.

Charleston's 21-year-old touring pro now has one.

Rogers delivered 11 aces in overwhelming world's 16th-ranked Carla Suarez Navarro of Spain, 6-4, 6-0, on Thursday in the round of 16 of the WTA Tour's $250,000 red-clay tournament in Bad Gastein, Austria.

This could be a major breakthrough for Rogers, a fourth-year pro ranked No. 147. She has won four straight matches, including two in the Bad Gastein qualifying tournament, and eight of her last 10 matches.

Rogers needed only 90 minutes to polish off the third-seeded Navarro on Thursday in the initial meeting between the two players. In the process, Rogers saved 10 of 11 break points and won 70 percent of her first serve points.

For Rogers, who upended 94th-ranked Kristyna Pliskova of the Czech Republic in a three-set opening round match on Tuesday, the victory over Navarro was her first over a top 20 player.

Rogers now advances into Friday's quarterfinals against 40th-ranked, seventh seed Camila Giorgi of Italy. This will be Rogers' first appearance in a WTA Tour quarterfinal.

The 22-year-old Giorgi scored a 6-0, 6-2 win over wild-card Lisa-Marie Moser of Austria in the round of 16.

Rogers and Giorgi's only previous meeting came in 2011 at Rock Hill where Giorgi posted a 6-3, 6-4 win on hard surface.
