The 2026 edition of the ATP Buenos Aires 250 series event sees the remaining Round of 16 matches on the schedule. Top seeds are in action and it promises to be a great day of tennis. As ever, we preview and predict all the scheduled matches for you.  But who will advance?

ATP Buenos Aires Day 4 Predictions
Juan Manuel Cerundolo vs Pedro Martinez

Head-to-Head: First Meeting

Juan Manuel Cerundolo comes into this matchup looking much more settled and confident after an impressive first-round win where he knocked out the fifth seed Daniel Altmaier. Both players are well suited to clay and enjoy long baseline exchanges, so expect a physical slugfest with plenty of momentum swings. Cerundolo’s recent form should give him the edge in the key moments.

Prediction: Cerundolo in 3

Luciano Darderi vs Tomas Barrios Vera

Head-to-Head: Darderi 1-0 Barrios Vera

Tomas Barrios Vera comes into this match with decent confidence after reaching the semifinals of a Challenger event a couple of weeks ago, but this represents a significant step up in level on the main tour. Luciano Darderi impressed at the Australian Open by reaching the fourth round and has looked comfortable dictating play with his aggressive baseline game. That attacking style should give him a clear advantage here.

Prediction: Darderi in 2

Camilo Ugo Carabelli vs Mariano Navone

Head-to-Head: First Meeting

This all-Argentine clash promises to be tight. Mariano Navone made short work of his opponent in the first round, while Camilo Ugo Carabelli arrives full of confidence after winning a Challenger title last week and also looking sharp in his opening match. With both players feeling comfortable on clay, expect long baseline rallies throughout the match, but Ugo Carabelli’s slightly superior baseline consistency may just give him the edge.

Prediction: Ugo Carabelli in 3

Sebastian Baez vs Ignacio Buse

Head-to-Head: First Meeting

Sebastian Baez has enjoyed an excellent start to the season, reaching the finals in Auckland. Additionally, clay remains his favourite surface. The Argentine is firmly among the contenders this week and will be no doubt be lifted by the strong home support. Ignacio Buse, the young Peruvian, showed plenty of fight in the first round in his first tournament of the year, but this is a tough step up in class. Baez’s experience and consistency should prove decisive.

Prediction: Baez in 2
