VIENNA: Top-seeded Juan Martin del Potro won his 12th career title Sunday, beating qualifier Grega Zemlja of Slovenia 7-5, 6-3 at the Erste Bank Open.
It's only the second indoor title for the Argentine, who was playing his first event since returning from a right wrist injury that sidelined him for more than a month.
At 2-2 in the opening set, the eighth-ranked Del Potro lost serve for the first time in the tournament. But from 2-4 down, he won 11 of the next 15 games to close out the victory.
The 70th-ranked Zemlja, who upset Janko Tipsarevic in the semifinals, was the first player from Slovenia to reach a final. Finland's Jarkko Nieminen, who won in Sydney, remains the only qualifier to win an ATP tour event this season.
