Andrey Rublev enters the ATP 250 event in Estoril as the top seed following his clay-court title in Bastad. The Russian will make his tournament debut in the round of 16 against Kazakhstan’s Timofey Skatov, who entered the main draw as a lucky loser.

Skatov received his spot after British player Jan Choinski withdrew from the event.

Pablo Carreño Busta also reached the round of 16, defeating Vilius Gaubas in the opening round.
