Olympic tennis champion Alexander Zverev won a long, exciting opening match at the season finale due to the abandonment of his opponent Matteo Berrettini. The world number three from Hamburg led 7: 6 (9: 7), 1: 0 against the crowd favorite when his opponent had to leave the pitch due to an injury on Sunday evening in Turin. Zverev thus made the first step on the intended path to the semi-finals of the ATP Finals. "I feel bad right now," said Zverev. “I don't know what to say because that's the worst feeling a player can have. I am very sorry for Matteo. "

Unimpressed by frenetic Italian fans, the world number three from Hamburg had previously secured the very competitive first set.

At the beginning of the second round, Berrettini then dropped the bat on the floor in the second game, received treatment and briefly tried to defend himself again, but had to acknowledge that he could no longer play.

In his second match of these ATP Finals on Tuesday, Zverev will soon see the Russian defending champion Daniil Medvedev in a duel between two opening winners.

The US Open winner started with a 6: 7 (5: 7), 6: 3, 6: 4 against the Polish tournament debutant Hubert Hurkacz.

Semi-finals against fellow favorite Medvedev

Zverev must be at least second in his group of four in order to reach the semi-finals next Saturday.

The year-end tournament of the eight best tennis professionals of the season won the Hamburg-based man three years ago and this time, after several successful months, he is one of the favorites - as well as Medvedev.

Zverev had no chance against the second in the world rankings at the Masters 1000 tournament in Paris on Saturday a week ago, also because he felt drained from the exertions of the past few months.

Berrettini was enthusiastically cheered on by the audience in the hall, which was not completely filled due to the Corona crisis.

But Zverev was not impressed by the atmosphere.

“I'm a fan of it when it's loud in the stadium.

I also like it when people are against me, ”he said before the match.

The number three in the world had an advantage in the longer rallies, served strongly and was closer to a break than the Italian from the start. However, the hamburger did not take advantage of his opportunities to remove the service from his opponent. So it stayed tight and suddenly Berrettini had his first two break chances at 5: 6 from Zverev's point of view, which were equivalent to set balls. Zverev saved himself in the tiebreak and won the first round after 79 minutes before the match came to a dramatic and unexpected end.

For the first time, the tennis elite compete in the multi-purpose hall Pala Alpitour, until 2025 after twelve years in London, the event was awarded to Turin.

It's "great fun" in the "mega atmosphere", said doubles player Kevin Krawietz, although he got off to a bad start.

In the expected difficult opening match against the Wimbledon and Olympic champions Nikola Mektic and Mate Pavic from Croatia, he lost 4-6, 4-6 with the Romanian Horia Tecau.

“Of course you're a bit disappointed with the match,” said the man from Coburg: “It's of course annoying that we get two breaks.

We would have wanted to make that closer. "
