GENEVA (AP) Former top-10 player Janko Tipsarevic used his wild-card entry to beat Peter Gojowczyk of Germany 7-5, 7-5 in the Geneva Open first round on Monday.
Now ranked No. 317, the 34-year-old Tipsarevic is back in ATP Tour main draws after missing the 2018 season for hamstring injuries to heal.
Fifth-seeded Radu Albot advanced to the second round on a day when two seeded players lost in the final week of clay-court warmups for the French Open.
Albot beat qualifier Lorenzo Sonego 7-6 (6), 7-6 (3), after 92nd-ranked Hugo Dellien beat eighth-seeded Andreas Seppi 6-1, 3-6, 6-4, and seventh-seeded Matthew Ebden lost to Nicolas Jarry of Chile 6-2, 7-6 (4).
Rain cut short play and gave former No. 3 Grigor Dimitrov a day off after playing through two qualifying rounds.
