Marcel Granollers and Horacio Zeballos will make their seventh consecutive appearance at the Nitto ATP Finals. The Spanish-Argentine duo advanced to the championship match in 2023 and the semi-finals in 2020 and 2021, falling to the eventual champions on each occasion.

The veteran doubles players successfully defended their title at Roland Garros this year, and they also reached finals at the ATP Masters 1000 event in Rome and the ATP 500 event in Dallas. 

Granollers will make his 11th appearance at the Nitto ATP Finals and try to secure his second crown after lifting the trophy with Marc Lopez in 2012. 

This will be Zeballos' seventh appearance in the season finale.
