Nuno Borges will face reigning champion Carlos Alcaraz in the second round of the Barcelona Open after a 6-2 6-3 triumph over Ilya Avashka on Monday.

Borges created a remarkable 20 break points, converting only five but still comfortable against his 61st-ranked opponent.

That sets up a clash with number one seed Alcaraz, who beat Pablo Carreno Busta in the 2022 final.

Ben Shelton's 7-5 6-4 success over countryman Mackenzie McDonald means he will take on Casper Ruud, while Bernabe Zapata Miralles will play Roberto Bautista Agut in an all-Spanish second-round affair after earning a routine 6-2 6-2 win over unfancied Attila Balazs.

Meanwhile, Emil Ruusuvuori beat Alexander Bublik in Barcelona for a second straight year to set up a second-round meeting with fifth seed Frances Tiafoe.

At the BMW Open in Munich, 2022 winner Holger Rune will open his defence against Yannick Hanfmann after the German battled from a set down to beat Thiago Monteiro 6-7 (3-7) 7-6 (7-5) 6-2.

Marcos Giron reached the second round with a 6-1 5-7 6-2 victory over Roberto Carballes Baene.
