GSTAAD, Switzerland (AP) Viktor Troicki returned from a one-year ban for a doping rules violation with victory in the Swiss Open first round on Monday.
Now ranked No. 847, the 28-year-old Serbian beat eighth-seeded Dominic Thiem of Austria 7-6 (4), 6-4.
Troicki was ranked No. 53 last July when the International Tennis Federation imposed an 18-month ban. He had refused to give a blood sample after losing at the Monte Carlo Masters in April 2013.
