Lorenzo Musetti planned a pizza celebration after landing his second title of 2022 by seeing off Matteo Berrettini in an all-Italian final at the Napoli Cup.

The 20-year-old, who won his first ATP Tour trophy on clay in Hamburg in July, scored a 7-6 (7-5) 6-2 victory over an injury-hampered opponent.

After defying advice from his team to abandon his semi-final on Saturday, Berrettini, bothered by a foot problem, showed up for Sunday's title match and generally moved well but could not prevent Musetti getting his hands on the trophy.

Musetti's win at the hard court event saw him match Berrettini – twice a champion during the grass season –  on two titles this year. 

They are the only Italians with multiple ATP singles titles in 2022, with Musetti now increasingly close to joining compatriots Berrettini and Jannik Sinner inside the top 20.

This win nudges him a place to number 23 in the rankings, a new career-high position, and it made Musetti the ninth player on the men's tour to win a tournament this year without dropping a set at any point.

Speaking in an on-court ATP interview, Musetti said: "It was a really tough first set. Really long and we never broke.

"Matteo is a competitor; even if he was not 100 per cent physically, his capacity to stay until the end, to fight until the end, was a big problem for me to solve.

"Today I think I played not the best tennis, because I think we were both really emotional, really nervous and there was a lot of tension, but in the important moments I played better.

"It's really nice to be here with my family, with the crowd, and it's a really big win for me and an important moment for my career.

"I hope to enjoy and celebrate with great pizza. I will probably enjoy a Pizza Margherita for sure, like Napoletana."

Matteo Berrettini is set to tackle Davis Cup team-mate Lorenzo Musetti in an all-Italian Napoli Cup final on Sunday after defying advice to pull out with a foot injury.

Former Wimbledon runner-up Berrettini beat American Mackenzie McDonald 3-6 7-6 (7-2) 6-3 at the hard court event, while Musetti came through 6-3 6-4 against Serbian Miomir Kecmanovic.

Providing Berrettini is healthy to participate in the final, the tournament looks set to deliver a crowd-pleasing trophy match, but it was touch and go whether the Rome native would get through the McDonald match.

"I don't even know how I did it," Berrettini said. "I wasn't feeling very good. I asked for the physio because my foot was hurting. It happened so many times in my career that I had to fight through so many things, not just thinking about the tennis ball."

He added, quoted by the ATP: "I didn't want to retire. My team told me, 'I think you should stop'. But I tried and I found a way."

Berrettini and Musetti have never gone head-to-head before. Berrettini has won two titles this year, both on grass, in Stuttgart and at London's Queen's Club, while 20-year-old Musetti scooped his maiden ATP title on clay in Hamburg.

At the European Open in Antwerp, Sunday's final will see American Sebastian Korda tackle Canadian Felix Auger-Aliassime, in a battle of two in-form players.

Korda was runner-up last week in Gijon, while Auger-Aliassime took the title in Florence, adding to his Rotterdam triumph from February.

Korda wrestled his way past a recently resurgent Dominic Thiem, scraping a 6-7 (4-7) 6-3 7-6 (7-4) victory, before Auger-Aliassime was given a mighty battle by veteran Frenchman Richard Gasquet, winning through in two tight sets, 7-6 (7-2) 7-6 (7-3) his margin.

Like Berrettini and Auger-Aliassime, Greece's Stefanos Tsitsipas has a third title of the year in his sights this weekend.

Tsitsipas swept through to the final of the Stockholm Open with a 6-2 6-2 win over Finland's Emil Ruusuvuori, setting up a clash with 19-year-old Danish player Holger Rune.

For Rune, there was no such straightforward path into the final as Alex de Minaur pushed him all the way, with the Australian eventually edged out 4-6 7-6 (7-1) 7-5 after two hours and 50 minutes.

Grigor Dimitrov crashed out of the Stockholm Open to the unseeded Jiri Lehecka in a three-set thriller on Tuesday, as Botic van de Zandschulp also fell at the first hurdle at the European Open.

Dimitrov, seeded sixth in the Swedish capital, came up short against Lehecka, who seized a surprise 6-4 1-6 7-6 (7-5) win, his first on the ATP Tour since July.

Victory for Alex de Minaur was far more predictable, a 150th at tour level coming courtesy of a straight-sets defeat of Benjamin Bonzi.

In Antwerp, Dominic Stricker handed Van de Zandschulp a swift exit, winning 6-2 6-4 to stay on Lehecka's coat tails in pursuit of a place at the Next Gen ATP Finals.

Stricker's reward for this win will be a second-round encounter with French veteran Richard Gasquet, who knocked out three-time grand slam champion Stan Wawrinka on Monday.

At the Napoli Cup, fifth seed Miomir Kecmanovic saw off wildcard Flavio Cobolli with ease, but others found life rather tougher.

Respective seventh and eighth seeds Albert Ramos-Vinolas and Adrian Mannarino fell to Nuno Borges and Pedro Cachin.
