Francisco Comesana will face Alexandre Muller in the semifinals of the Rio Open. This will be the very first meeting between the two.

Comesana booked his place in the last four of the ATP 500 event after stunning Alexander Zverev 4-6, 6-3, 6-4. The Argentine has also beaten sixth seed Nicolas Jarry and Gustavo Heide during the tournament. Muller reached the semifinals after beating fourth seed 7-5, 6-1.

Muller has had an impressive start to the 2025 season, winning eight out of ten matches so far while Comesana has triumphed in three out of six main-draw fixtures. The Frenchman's current form makes him the favorite but if the Argentine is able to replicate his performance against Zverev, there is a fair chance of him coming out on top and reaching the final.

Predicted Winner: Francisco Comesana.
