Kitzbuhel, Austria (SportsNetwork.com) - David Goffin of Belgium rallied for a three-set win over Austria's Dominic Thiem on Saturday to capture the Kitzbuhel Cup for his first ATP World Tour title.

Goffin earned a 4-6, 6-1, 6-3 victory in the final, his first on the ATP World Tour. He entered this week's tournament as a wild card after a strong run on the Challenger Tour in July.

The 23-year-old now has a 20-match winning streak, capturing three titles on the Challenger circuit since a first-round loss to Andy Murray at Wimbledon.

"It's a great day for me, to win an ATP (title))," said Goffin. "It's just an amazing feeling right now. I don't believe it. Maybe in a few days I'll realize what happened today."

Goffin has had a difficult season on the ATP World Tour, as he entered this week's event with just one match victory in his last seven events. That win, however, came against Thiem in the first round of the Wimbledon tune-up at the Queen's Club.

Thiem was hoping for a different outcome on Saturday and took the first set. He had a chance to break early in the second, but squandered two break points in the third game and Goffin ran away with the match from there.

Goffin reeled off seven straight games, opening a 2-0 lead in the third set. He broke in the final game to seal the first tournament title for a Belgian since Xavier Malisse won at Delray Beach in 2007. The last Belgian to win at Kitzbuhel was Filip Dewulf in 1997.

Thiem, seeded fifth this week, was trying to become the first Austrian to win his home tournament since Thomas Muster in 1993. At 20 years old, Thiem was the youngest finalist on the ATP World Tour this year.

"It was an amazing week for me and the crowd gave me huge support during every match," said Thiem. "Of course I'm very disappointed. But I lost against an extremely strong opponent, who didn't commit a lot of mistakes and played with a lot power."

Goffin claimed a first prize of $103,500.
