CHARLESTON, SC, USA -- Hungarian qualifier Fanny Stollar pulled off a stunning upset in the second round of the Volvo Car Open on Wednesday, ousting No.6 seed Johanna Konta of Great Britain, 6-3, 6-4.

"I think I pushed my game to her and I stayed really aggressive and I could push her back behind the baseline, so that helped a lot," Stollar told the press after the match.

The 19-year-old blasted 28 winners to outlast the World No.22 in one hour and 20 minutes. She also won 62 percent of points on the Konta second serve, and never faced a break point in the second set. It was the second straight upset on Volvo Car Stadium after Kristyna Pliskova's shock defeat of second seed Petra Kvitova.

This is the second consecutive year that Stollar qualified for the main draw in Charleston and eliminated a Top 25 player en route to a third round appearance. The Hungarian defeated then-14th-ranked Elena Vesnina in the first round last year.

"I honestly can't tell you what it is," replied Stollar, when asked about her strong performances in Charleston. "I just feel pretty good here and relaxed and [I'm] just enjoying it here."

"I'm trying to play my game, just my style in every tournament, and it works good here," Stollar continued. "But yeah, I hope I can bring it out in other tournaments, too."

Stollar, ranked World No.219, will face another seeded player in the third round, as her next opponent will be 12th-seeded Dutchwoman Kiki Bertens, who beat Serbia’s Aleksandra Krunic 6-4, 6-2, earlier on Wednesday.

"I'm going to just try to play my game and just keep being aggressive," said Stollar.

"It feels good, you know, but it's still not over," the teenager continued. "I still have matches to go and I don't want to stop here."

Right off the bat, Stollar continued with her solid play on the Charleston courts, which led her to the third round last year, as well as to a comprehensive victory over fellow qualifier Francesca Di Lorenzo in the opening round of this year's event. The Hungarian opened the match with an ace, and held her nerve during a stretch of four consecutive breaks of service leading to 3-3.

A sturdy hold by the teenager at 4-3 stopped that run of breaks, and she made the most of that turn of events, breaking Konta for the third straight time after the Brit sent numerous errors long off of both wings.

Stollar closed out the first set with ease in the next game, posting 11 winners, to only four by Konta. The British No.1 was also heavily undone by eight unforced errors in the opening frame, doubling her amount of winners.

In the second set, both players held serve without much struggle up to 3-3, neither facing a break point up to that juncture.  In the next game, Konta saved a break point with a forehand winner, holding for 4-3, but Stollar stayed unfazed, tying the set at 4-4 with minimal fuss.

It was Konta who would crack first in the second set, getting into trouble on her serve in the following game, and handing Stollar triple break point after a forehand miscue. Konta saved the first with an ace, but another unforced error from the Brit's forehand wing gave Stollar the pivotal break.

At 5-4, an ace gave the Hungarian a 30-0 lead, but Konta drew back to 30-30 behind sturdy play off the backhand side. But on the next point, a Stollar groundstroke took a bad bounce, and Konta unfortunately whiffed a forehand, giving Stollar match point. A long forehand by Konta sealed victory for the youngster, giving Stollar another great showing in Charleston.
