Plava Laguna Croatia Open Umag
Hungarian qualifier Attila Balazs stunned No. 3 seed Laslo Djere, downing the Serb 6-2, 6-4 in one hour, 40 minutes in the semifinal at Umag, Croatia.
In the final on Sunday, he will meet another Serb in fourth-seeded Dusan Lajovic, who was up one set when his opponent, Italian Salvatore Caruso, retired. Serving at 5-6, 0/15, Caruso injured his right leg while attempting to reach a ball. He took a medical timeout after the first set, then played three points in the second set before retiring.
It will be the first ATP Tour final for Balazs. Lajovic was defeated in his first tour final in April at the Rolex Monte Carlo Masters by Italian Fabio Fognini.
