Second-round matches will conclude on Day 4 (Thursday, April 30) of the ATP Challenger Cagliari 2026. Fifth seed Lorenzo Sonego has been the only notable casualty so far, going down to Mattia Bellucci in three sets in the first round.
Former top 10 players Matteo Berrettini and Hubert Hurkacz headline Thursday’s order of play. Here are the predictions for all the singles matches set for Day 4 of the ATP Challenger Cagliari:
Thanks for the submission!
#1. Matteo Berrettini vs Mariano Navone
Berrettini fought past Patrick Kypson to reach the second round of the ATP Challenger Cagliari. He improved his record on clay to 6-6 with the win. Defending champion Navone received a first-round bye. He won the title in Bucharest at the start of the clay swing, and has an 8-5 record on the surface.
Berrettini leads their rivalry 2-0. Both of their previous matches were on clay. He won their recent encounter at the Monte-Carlo Masters 2025 in straight sets. His record in this rivalry makes him the favorite to win this match despite Navone having better results on clay than him this year.
Winner: Matteo Berrettini
#2. Marcos Giron vs Aleksandar Kovacevic


Giron kicked off his ATP Challenger Cagliari campaign with a 6-4, 1-6, 6-1 win over Aleksandar Vukic. Kovacevic beat Luca Potenza 6-3, 7-6 (3) in the first round. This marked the first win of the clay swing for both players.
Giron won their previous and only encounter at the Indian Wells Masters 2023 in straight sets. His 13-9 record for the season outshines Kovacevic’s 10-12 record by a slim margin, thus making him the slight favorite to win this duel.
Winner: Marcos Giron
#3. Hubert Hurkacz vs Emilio Nava
Hurkacz has a 4-2 record on clay, and he made the third-round of the Monte-Carlo Masters. He beat Zachary Svajda 6-2, 7-6 (6) in the first round of the ATP Challenger Cagliari. Nava has gone 11-8 on clay this year, and advanced to the second round here following Damir Dzumhur’s mid-match retirement.
This will be the first meeting between them. Nava has challenged the likes of Ben Shelton and Jiri Lehecka on clay this year, pushing them to three sets before coming up short. He could one-up Hurkacz, who hasn’t been as successful as him on clay this year.
Winner: Emilio Nava
#4. Juan Manuel Cerundolo vs Matteo Arnaldi


Arnaldi and Cerundolo needed three sets to beat Federico Arnaboldi and Federico Cina respectively in the first round. Arnaldi snapped his four-match losing skid and improved his record on clay to 2-4.
Cerundolo tallied his 12th win on clay this year, against eight losses. This will be his first meeting with Arnaldi. The Italian’s shaky form on clay makes him the underdog in this contest.
Winner: Juan Manuel Cerundolo
#5. Roman Andres Burruchaga vs Andrea Pellegrino
Winner: Roman Andres Burruchaga
#6. Nuno Borges vs Cristian Garin
Winner: Nuno Borges
#7. Adrian Mannarino vs Jesper de Jong
Winner: Jesper de Jong
#8. Mattia Bellucci vs Gianluca Cadenasso
Winner: Mattia Bellucci
