Albert Ramos-Vinolas and Roberto Carballes Baena will meet in an all-Spanish Ecuador Open final after three-set wins on Sunday (AEDT).

Ramos-Vinolas, the No.2 seed at the ATP 250 event in Quito, overcame Brazilian Thiago Monteiro 6-4 6-7 (4-7) 6-4 in their semi-final.

The Spaniard's victory saw him move into a sixth ATP World Tour final — his fifth on clay — as he eyes just his second title and first since 2016.

Awaiting him in the decider is Carballes Baena, who beat fellow qualifier Andrej Martin 4-6 6-3 6-2.

With his win, the world No.107 progressed to a maiden ATP final.

Ramos-Vinolas and Carballes Baena have met twice on the ATP World Tour, with the former winning both previous clashes.
