Stan Wawrinka, a three-time Grand Slam winner, got knocked out in the first round of the Sofia Open by last year’s runner-up Marius Copil on Monday.
In what was a third career meeting between both men, Wawrinka started strongly, closing out the first set in just 23 minutes. But Romania’s Copil, who’s ranked 56th in the world, brushed aside his sluggish start, producing a resilient display to clinch the second set in a tiebreaker and level the match.
Copil would go on to claim the third set and the match 3-6, 7-6(5), 6-4 for his first career victory over Wawrinka, who’s now ranked 57th in the world, and move into the second round.
“It’s great to start with a win against Wawrinka,” said Copil “I made a few mistakes at the beginning. I had to change things, I knew I had to stay in the game after losing the first set.
“I served well today,” added the Romanian. “The serve has always been my main weapon.”
Next up for Copil is the winner of the first round clash between 6th seed Fernando Verdasco and Bulgarian qualifier Alexandar Lazarov.
In the other match played, Matthew Ebden defeated Adrian Andreev 6-3, 4-6, 7-6(5) to make progress.
Top seed, Karen Khachanov will kick-start his campaign in the second round against the winner of the first round match between Uzbekistan’s Denis Istomin and Italian Matteo Berrettini, while second seed, Stefanos Tsitsipas of Greece, who also received a first round bye, will play against Germany’s Jan-Lennard Struff or Italy’s Stefano Travaglia in the second round.
Tsitsipas reached the semifinals of the Australian Open in January and will be seeking to build on that momentum in Sofia.
