Nuno Borges vs Felix Auger Aliassime 15 June 2026 Prediction

Auger-Aliassime likely remembers that he could not finish his Australian Open match against Borges at the start of the year. At the time, it looked like a major setback for the Canadian after a strong 2025 season. In Halle, Felix will face the Portuguese player again.

Surface speed: 8/10

Nuno Borges

Nuno is a solid mid-tier player who briefly reached the top 30 a couple of years ago. He has lost some ground since then and is currently around No. 50 in the live rankings. His 2026 season has been modest at 14-18, with his best results coming at the Majors in Melbourne and Paris, where he reached the third round.

Borges is a typical baseline player with a fairly good serve, winning 82% of his service games in 2026. His problems start on return, especially against opponents’ second serves, where he has won only 46% of points this season.

Grass is far from Borges’ favorite surface. Across his career, he has won only 42% of his matches on it, going 11-15. Last week, Nuno played in 's-Hertogenbosch, where he beat Atmane (6-4, 6-4) before losing to Cilic (6-3, 6-7, 3-6).

Felix Auger-Aliassime

After a run of average clay-court tournaments, Felix raised his level at Roland Garros, where he reached the quarterfinals before losing to Cobolli (6-4, 4-6, 4-6, 4-6). Faster courts suit him better, so the world No. 4 enters the grass swing with reasons for optimism.

Auger-Aliassime’s main weapon is his powerful serve, which becomes even more dangerous on grass. In 's-Hertogenbosch, he had not fully found his range yet, with 12 aces across two matches, which is a low number by Felix’s standards. Even so, last week the Canadian consistently won more than 75% of points behind his first serve.

The world No. 4 still has no titles on grass, and his overall record on the surface is not especially strong at 33-22 for his career. With his physical tools, however, Auger-Aliassime has everything needed to keep improving on grass courts.

Tournament History in Halle

• Borges is playing in Halle for only the second time in his career. In 2024, he lost to Medvedev in the first round in two sets, 6-7, 4-6.
• Auger-Aliassime has appeared at this ATP 500 event more often. In 2021, he reached the semifinal, losing to Humbert (4-6, 6-3, 6-7). In 2022, he stopped in the quarterfinals, losing to Hurkacz in two tiebreaks (6-7, 6-7).

Nuno Borges vs Felix Auger-Aliassime Prediction: Borges Set Handicap +1.5

• Main prediction: The bookmakers give Auger-Aliassime around a 65% chance to reach the second round. On paper, he is the favorite. However, on grass, the gap in class may not be as clear. Last year, Felix was also a clear favorite against Djere at this tournament, but that match became a real test for the Canadian (6-3, 6-7, 6-1). Nuno is capable of taking a set from the world No. 4. Last week in 's-Hertogenbosch, he beat Atmane confidently and could have had a real chance against Cilic before rain disrupted the match. We recommend looking at Borges set handicap +1.5 at 1.82.
• Total prediction: In Melbourne, Nuno took two sets from Felix before the Canadian retired. Their 2025 meeting in Dubai is even more relevant: Auger-Aliassime won a deciding-set match, 4-6, 6-3, 7-5. We believe the Portuguese player will have chances even on grass. He is in decent form, which he showed at the recently completed Roland Garros. Consider over 23.5 games at 2.03.
