Alfie Hewett and Gordon Reid failed to retain their Wheelchair Masters doubles title with a straight-set defeat by Martin de la Puente and Joachim Gerard in the Netherlands.
The British duo, who won the title for a third time together in 2023, lost 6-4 6-2 to the Spanish-Belgian pair.
Reid and Hewett, who clinched the Paralympic doubles title in Paris this summer, had previously won the season-ending tournament in 2017 and 2021.
Reid has a second shot at silverware in Arnhem, however, after sealing his place in the singles final earlier on Saturday.
He defeated De la Puente 6-2 6-1 in his semi-final, but defending singles champion Hewett could not make it an all-British affair as he was beaten 6-4 4-6 6-3 by Japan's Paralympic champion Tokito Oda.
Reid has never won the Wheelchair Masters singles title, a status he will look to change in Sunday's final against 2022 champion Oda.
