Alfie Hewett and Gordon Reid failed to defend their Wheelchair Masters doubles title with a straight-sets defeat to Martin de la Puente and Joachim Gerard in the Netherlands.
The British duo, who won the title together for the third time in 2023, lost to the Spanish-Belgian duo 6-4 and 6-2.
Reid and Hewett, who won the Paralympic doubles title in Paris this summer, had already won the season-ending tournament in 2017 and 2021.
However, Reid has a second chance at the title in Arnhem, having already secured his place in the individual final on Saturday.
He beat De la Puente 6-2, 6-1 in his semi-final, but defending singles champion Hewett couldn't make it an all-British affair as he fell to Japanese Paralympic champion Tokito Oda 6-4, 4 :6, 6:3 was beaten.
Reid has never won the Wheelchair Masters singles title, a status he will look to change in Sunday's final against 2022 champion Oda.
