The 65th-ranked Goerges, playing in her first final, broke Bacsinszky three times and won the opening set when the second-seeded Swiss player double-faulted on set point.

Bacsinszky led 4-2 in the second set but then was broken twice as the 21-year-old Goerges wrapped up the victory.

“I've played really well all week,” said Goerges, who laid down on the court in celebration.

“It was my first final and I just wanted to enjoy it as much as possible. I didn't put pressure on myself,” said Goerges, who won five events on the lower-ranked ITF circuit.

Andrea Petkovic of Germany also clinched her first title in Bad Gastein last year.

It was the first final of the season for the 52nd-ranked Bacsinszky, who is now 1-1 in finals after winning in Luxembourg in 2009.

Goerges dictated the pace in the opening set with strong shots from the baseline, which forced Bacsinszky into errors.

Bacsinszky succesfully slowed down her opponent with high top spin shots in the second set, but Goerges again found her rhythm after she lost serve when trailing 3-2.

The German netted a forehand on her first two match points but converted the third with a drop shot.

Earlier Sunday, Goerges beat France's Alize Cornet by the same score in a semifinal that was rescheduled from the previous day because of rain.

Goerges dominated the first set with powerful ground strokes and converted all three break points against Cornet. Both players struggled to hold serve in the second set before Goerges won on her first match point.

The $220,000 Gastein Ladies was the last clay-court tournament of the season.

In Hamburg, Germany, Kazakhstan's Andrey Golubev caused an upset here on Sunday by defeating Austria's Jurgen Melzer 6-3, 7-5 in the final of the Hamburg ATP tournament to claim his first tour title.

Melzer, the world No. 15, reached the semifinals at the French Open last month, where he lost to Rafael Nadal, and also tasted success in the Wimbledon men's doubles event alongside Germany's Philipp Petzschner.

"It's brilliant, I'm really happy," said Golubev, the world No. 82.

"I've played extremely well this week." The 23-year-old's best previous result at an ATP tournament was a runner-up finish at the St Petersburg Open in 2008.

"He hits the ball hard and when he hits it well, he's difficult to beat," said Melzer.

In Atlanta, Mardy Fish extended his winning streak to nine matches by defeating top seeded Andy Roddick 7-6, 6-3 on Saturday to advance to the final of the Atlanta Tennis Championships.

Fish will meet second seed John Isner in the final after the towering American overcame stifling heat to beat unseeded South African Kevin Anderson 6-3, 6-7, 6-3.

Sixth seeded Fish had a poor service game, making just 40 percent of his first serves, but saved all three break points and broke Roddick in the only chance he received.

"It's not something I try to do, but when I beat (Roger) Federer at Indian Wells I only served at 35 percent," Fish said.

Isner overcame seven break points and sweltering heat in his afternoon match against Anderson to advance to his fourth final of the year.

"The conditions were just brutal," Isner said. "It took a lot out of me (and) without clouds the sun was just beaming down." Isner had an opportunity to close out the match in the second set and escape the torturous heat when he held match point in the tiebreak but hit a forehand long and Anderson capitalized to send the match into a decider.

Both players battled fatigue in the final set, before Anderson double faulted to allow Isner to convert the only break point opportunity of the set and take a 5-3 lead, which he converted into victory.

"I started well in the third set but then I played an average service game and he took advantage of that," Anderson said.

"I was making him work harder for his service games than he made me work for mine, but he capitalized on the break points and I didn't."
