Matteo Berrettini earned his second Swiss Open title on Sunday with a commanding straight-sets victory over Quentin Halys.

It took just 59 minutes for the Italian to dispatch the qualifier 6-3 6-1 in Gstaad for his ninth ATP Tour title.

The players were evenly matched through the opening six games, but Berrettini got a vital break in the seventh to swing momentum in his favour just before play was suspended due to rain.

When play was resumed half an hour later, Berrettini, who was 5-3 up, wasted no time regaining control, winning the next six games in a row.

Halys stopped himself from being on the wrong end of a bagel scoreline as he held off the former world number six in the penultimate game, but all he did was hold off the inevitable. 

Data Debrief: Berrettini reenters winner's circle

Berrettini lifted his second Tour title of the year, winning in Gstaad for the first time since 2018, having lost in his last final appearance in 2022.

He did not give Halys a sniff - he won nine games in a row to put himself out of reach, while also winning 33 of his 37 service points (89%) and getting four breaks.

Casper Ruud defeated Quentin Halys in a third-set tie-break to reach the final of the Estoril Open, where Miomir Kecmanovic awaits after defeating Marco Cecchinato.

The number one seed, competing in his first semi-final of the season, prevailed 6-4 3-6 7-6 (7-2) in Portugal to move within one match of a 10th singles title.

Ruud broke his opponent's serve in the opening game and saw out the first set, but Halys – competing in his first ATP Tour semi-final – hit back in the second to prolong the match.

Both men held as the contest went the distance, but Ruud's quality told as he raced 3-0 ahead in the deciding tie-break and did not look back as he set up a final with Kecmanovic.

World number 40 Kecmanovic needed a little over an hour to beat sixth seed Cecchinato, who had surprised Alejandro Davidovich Fokina in the previous round.

Kecmanovic, aiming to add to his only previous singles success in Kitzbuhel three years ago, held serve throughout to claim a 6-3 6-1 win over the 2018 French Open semi-finalist.

Elsewhere on Saturday, the final seeded player fell at the Grand Prix Hassan II as Dan Evans was defeated 2-6 6-4 6-2 by Roberto Carballes Baena.

Carballes Baena has now eliminated three seeded players and will face Alexandre Muller in Sunday's final after the Frenchman saw off Pavel Kotov in straight sets.

Muller edged a first-set tie-break and proved too strong in the second as he saw out a 7-6 (7-3) 7-5 victory in Marrakesh.

Casper Ruud is through to the final four of the Estoril Open after a routine 6-3 6-0 victory against defending champion Sebastian Baez on Friday.

The number one seed dominated his Argentine opponent from the moment the first set went to 3-3, winning nine-straight games from there to ease to victory.

Ruud did need to save four break points in the second game of the second set, but his ability to hold serve seemed to end any resistance that Baez could muster.

Halys reached his first ever ATP Tour semi after recording a 6-1 6-4 win over the former world number three in just one hour and 19 minutes.

The other semi-final will see Miomir Kecmanovic take on Marco Cecchinato after the latter stunned third seed Alejandro Davidovich Fokina in straight sets.

The world number 96 claimed a 7-5 7-6 (7-5) victory in the first meeting between the pair to set up a last-four clash with Kecmanovic, who saw off sixth seed Bernabe Zapata Miralles with a comfortable 7-5 6-2 win.

Elsewhere, Dan Evans is the only seed remaining in the Grand Prix Hassan II as he reached the semi-finals by cruising to a 6-3 7-5 triumph over world number 201 Andrea Vavassori in Marrakech.

Evans will face Roberto Carballes Baena next after the Spaniard toppled fourth seed Tallon Griekspoor 6-3 2-6 6-2.

Second seed Lorenzo Musetti was beaten by Alexandre Muller 6-3 1-6 6-4 in a topsy-turvy encounter, and the Frenchman will now face Pavel Kotov in the final four after the Russian defeated Christopher O'Connell in a thriller, 6-3 6-7 (6-8) 7-6 (7-3).
