World number six Felix Auger-Aliassime began his season with a straight-sets defeat by Australian qualifier Alexei Popyrin on Monday while Holger Rune crashed out to Yoshihito Nishioka in the ATP 250 Adelaide International 1 first round. Auger-Aliassime enjoyed a strong second half of the 2022 season, picking up titles in Florence, Antwerp and Basel, as well as helping Canada to the Davis Cup crown, but failed to reach those levels in a 6-4 7-6(5) loss to Popyrin.
