Felix Auger-Aliassime’s Nitto ATP Finals hopes suffered a setback on Friday at the Swiss Indoors Basel, where he was forced to retire against Jaume Munar after losing the first set.

The Canadian was trailing 3-6 when he walked to the net and ended proceedings after 45 minutes of his quarter-final match at the ATP 500.

Auger-Aliassime lifted the trophy in Brussels last week to move to ninth in the PIF ATP Live Race To Turin. The 25-year-old, who married Nina Ghaibi last month, is 340 points behind eighth-placed Lorenzo Musetti, who occupies the final qualification spot. Musetti is in quarter-final action against Cornetin Moutet in Vienna later on Friday.

Auger-Aliassime is hoping to make his second appearance at the prestigious year-end event, having competed in 2022. He holds a 43-21 record on the year, according to the Infosys ATP Win/Loss Index and is scheduled to compete at the Rolex Paris Masters next week.

Joao Fonseca followed Auger-Aliassime and Munar onto court and overcame Denis Shapovalov, who also retired. Fonseca led the Canadian 3-6, 6-3, 4-1 when Shapovalov approached the Brazilian to shake hands.

Fonseca is into his second tour-level semi-final of the year and first at ATP 500 level. The 19-year-old won his maiden tour-level crown in Buenos Aires earlier this year and is now 23-15 on the season. Fonseca is the second-youngest semi-finalist this century and will play Munar on Saturday.
