Emilio Nava was awarded the 2026 Neckarcup title after Luka Mikrut withdrew from the final with a shoulder injury, handing the American his seventh ATP Challenger trophy and his first of the season.

The 24-year-old arrived in Bad Rappenau as the second seed and produced one of the tournament’s sharper displays in the semifinals, a 6-1, 6-4 win over Henri Squire that lasted 58 minutes. After that victory Nava said: “Henri had an off day today, while everything worked for me.”

Sunday’s championship match never began after Mikrut addressed the Centre Court crowd and detailed his condition. “I have severe pain in my shoulder. I tried everything with the physios, the doctor, and pain medication,” the Croatian explained. “But I was worried that playing a match could make it even worse. To beat Emilio, I would need to be at 150 percent, not just 100. I wouldn’t have been able to do that today.”

Nava acknowledged mixed feelings on lifting the trophy. “It’s a bittersweet feeling today,” Nava admitted after lifting the trophy. “But this tournament has been fantastic. The organization is outstanding, and this was definitely one of the most enjoyable weeks of the year for us. I always love playing in Germany.”

The title continues the upward trajectory Nava has built since winning four Challenger trophies in 2025. “It was definitely my best season so far and I’m proud of what I achieved,” he said during the week. “Winning four Challenger titles is something special. But I still think my real breakthrough at ATP Tour level is ahead of me. These things don’t happen overnight.” Now World No. 87, Nava was also candid about the strength of American men on tour. “We’re just good players,” Nava joked. “Look at guys like Ben Shelton, Taylor Fritz, Tommy Paul, Frances Tiafoe, Brandon Nakashima and Alex Michelsen. They’re all doing great. We get along well, but we’re also extremely competitive. We push each other every day to become better players.”

Nava splits training between Buenos Aires and Florida. “My coach is from Spain and my physio is Argentinian, so naturally I spend a lot of time around Spanish-speaking people,” he explained. Off court he said, “I love video games. Right now, I’m playing a lot of Battlefield. I also enjoy going to the beach, relaxing and spending time with friends.” He added lighter moments from the week: “We played Frisbee in the park, spent time playing video games indoors, and shared a lot of laughs with the team and the other players.” Asked about celebration plans, he laughed: “I wish there was a big party,” he laughed. “But I’ll have dinner with my team and treat myself to some ice cream.”

Nava leaves Germany with 100 ATP ranking points and €23,700 in prize money. Tournament officials praised the level of play but noted attendance was low across eight days. “The level of tennis between world rankings 100 and 200 is outstanding,” said tournament manager Metehan Cebeci. “The week was sunny, rainy, emotional and exciting,” Tournament Director Mine Cebeci said. “And on finals day, I think we can all be very satisfied.”

Stefanos Sakellaridis completed a clear clay-court objective in Chisinau by winning the Moldova Open at the National Tennis Center. The 21-year-old Greek beat Romanian qualifier Cezar Cretu 6-7(1), 6-3, 6-3 in the final to secure the second ATP Challenger Tour trophy of his career.

On a mostly sunny but windy afternoon, Sakellaridis recovered after losing the opening set and displayed composure across two hours and 39 minutes. He delivered three aces, won 68% of his first-service points and claimed 52% of the total points to take the match.

“I am very happy winning this title,” Sakellaridis said. “My goal at the beginning of the clay-court season was to win a title on this surface and this is my last tournament on clay before the start of the grass swing. I was very focused this week and managed to turn this match around today.”

The victory follows his maiden Challenger title in New Delhi earlier this year and highlights continued progress over recent seasons. “That was great,” he said. “It was unexpected because I did not feel great about my game before the tournament. The day before it started, I changed my racquet and it clicked from the very first ball. I also had a good feeling during my first match. I managed to keep the momentum throughout the whole tournament. The support was also great and eventually winning the title was amazing, especially after coming back from 5-2 down in the final. It was very dramatic but created amazing memories for me.”

Arriving in Chisinau at a career-high ranking of world No. 197, Sakellaridis earned €23,750 and 100 ATP ranking points for the title, which will move him to a new career-high of world No. 153. “I would really like to continue moving up the rankings and playing bigger events,” said the Greek, who came in ranked No. 197.

He credited steady work and his training base at the Piatti Tennis Academy. “It has been good work over the last couple of years. I have been working on my game, and it has started to pay off. But there is still a long way ahead, and I hope that I can keep going and stay hungry for more. I would really like to continue moving up the rankings and playing bigger events.”

“It is a great experience there, especially with Riccardo Piatti, who has worked with so many top players. He is helping me a lot,” he said. Sakellaridis adapted better than most to the windy conditions and praised the new complex and the host city. Sakellaridis overcame “unpredictable” wind throughout the week.

“It’s my first time here. I went to the city center and it is very beautiful. I am happy to be here,” he stated.

“I believe a lot in my game. I can do many different things on the court. I can create a lot of opportunities and be dangerous during matches. But there is still a lot of work to do. I need to bring more spin into my shots, be more aggressive and also become more consistent on my serve. There is still a bit of fine-tuning to do, and then we will see what I can achieve in the future.”

The ATP Challenger Tour remains the essential first proving ground for players advancing toward the ATP Tour. For many established names the first Challenger title delivered ranking points, belief and a clear sign of progress.

“Guys at that level, they’re hungry,” says Tiafoe. “They’re trying to really start making a living, they’ve got families. They don’t care that you’re a junior phenom.” Frances Tiafoe recorded his first ATP Challenger Tour title in Granby, Canada (August 2016).

“It was a kind of a surreal introduction to the Challenger Tour,” Ruud says. “I entered qualies for this ATP Challenger in Sevilla, ranked about 550… I ended up winning the whole thing.” Casper Ruud’s first Challenger title came in Sevilla, Spain (September 2016).

“Winning the tournament was for me a bit shocking,” Fils recalls. “But I’m very happy with that victory, I remember it was one of the most important for me.” Arthur Fils earned his first Challenger crown in Oeiras, Portugal (January 2023).

“Once I won that tournament, it gave me so much confidence to feel like I was really progressing,” Norrie says. “It definitely tests your mental ability and your actual tennis ability as well.” Cameron Norrie captured his first Challenger title in Binghampton, NY, U.S.A. (July 2017).

“As a junior, you’re coming on after winning so many matches and feeling great about yourself. Then, all of a sudden, you get onto the Tour and you’re not winning as much. It really hits your confidence, and you have to learn how to deal with those losses,” says De Minaur. Alex de Minaur’s first Challenger triumph was in Nottingham, U.K. (June 2018).

Across these accounts the pattern is clear: early Challenger success offers a mix of practical rewards and psychological momentum. This week: Tune in to see Alejandro Tabilo, Jaume Munar and Zizou Bergs in Valencia.
