The top two seeds at the Rio Open remain on a collision course after both Carlos Alcaraz and Cameron Norrie advanced to the semi-finals on Friday.

World number two and top overall seed Alcaraz was strong in his 6-4 7-6 (7-0) victory over Serbia's Dusan Lajovic, improving his unbeaten record in 2023 to 6-0.

Alcaraz has his eyes set on his second title win in a row after also emerging triumphant in last week's Argentina Open.

Meanwhile, Norrie had to fight back from an early deficit to eliminate Hugo Delien 4-6 6-1 6-4, with the world number 13 and second seed now boasting eight wins from his past nine matches. The only loss during that stretch was to Alcaraz in the Argentina Open decider.

For a chance to avenge that loss, Norrie will have to beat Bernabe Zapata Miralles after he overcame Albert Ramos-Vinolas 6-4 2-6 6-4 in an all-Spanish quarter-final.

Alcaraz will contend with Nicolas Jarry, after the unseeded Chilean knocked out his second seeded opponent of the tournament, this time getting the better of Sebastian Baez 6-3 7-6 (7-3).
