His breakthrough came in 2019, at the unlikely location of Ilkley in northern England. At the ATP Challenger tournament there, he made it to the final, and two hours before the match, he learned that the winner would receive a wildcard into the main draw at Wimbledon. “I was up against Dennis Novak,” Köpfer recalls, “and hardly got a look-in in the first set, but I managed to turn it around in the second. In the third, he had a match point at 4-5, 30-40 on my serve but messed up his shot. Then it came down to a tiebreaker, with a place at Wimbledon up for grabs. That’s what happens sometimes – it all comes down to a few points.” A fact illustrated by Novak, who fired a ball into the crowd and smashed his racket repeatedly into his foot after the Ilkley match point.
