Jannik Sinner powered past Alexei Popyrin in straight sets on Wednesday to reach the last eight of the Qatar Open and edge closer to a possible final meeting with Carlos Alcaraz.
The Italian, playing his first tournament since losing to Novak Djokovic in the Australian Open semi-finals last month, eased to a 6-3, 7-5 second-round win in Doha.
Sinner will play Jakub Mensik in Thursday's quarter-finals.
Australian world number 53 Popyrin battled gamely but failed to create a break-point opportunity against his clinical opponent.
Sinner dropped just three points on serve in an excellent first set which he took courtesy of a break in the sixth game.
Popyrin fought hard in the second but could not force a tie-break as Sinner broke to grab a 6-5 lead before confidently serving it out.
World number one Alcaraz takes on Frenchman Valentin Royer in his second-round match later.
