Del Potro, Zemlja reach Erste Bank Open final
VIENNA (AP) Top-seeded Juan Martin del Potro and qualifier Grega Zemlja advanced to the final of the Erste Bank Open on Saturday.
Del Potro, a runner-up last year, defeated Gilles Muller of Luxembourg 7-6 (4), 7-6 (5) to reach his fourth final of the year, while Zemlja rallied to stun second-seeded Janko Tipsarevic 3-6, 7-6 (5), 6-2 to advance to a final for the first time.
The 70th-ranked Zemlja was 0-4 against top-10 players. The Slovenian played 15 sets to get to the final, Del Potro seven.
Del Potro is looking for his 12th career title and third of the season after winning in Marseille and Estoril. He is playing his first tournament since returning from a wrist injury that sidelined him for more than a month.
