Season finale will take place in Turin from 9-16 November

The Nitto ATP Finals doubles field is now complete.

Christian Harrison and Evan King will join Julian Cash/Lloyd Glasspool, Marcel Granollers/Horacio Zeballos, Marcelo Arevalo/Mate Pavic, Harri Heliovaara/Henry Patten, Joe Salisbury/Neal Skupski, Kevin Krawietz/Tim Puetz and Simone Bolelli/Andrea Vavassori in Turin from 9-16 November.

Harrison and King, playing a full season together for the first time, will make their debut at the season finale. They were guaranteed their place on Thursday when Hugo Nys and Edouard Roger-Vasselin fell at the Rolex Paris Masters.

Starting from qualifying at the Dallas Open, the debuting duo won 14 of 15 matches. That set the stage for their breakthrough season, becoming the first all-American team to qualify for the Nitto ATP Finals since 2018, when Mike Bryan and Jack Sock won the title.

King and Harris won titles in Dallas, Acapulco and Brussels, while also reaching the final in Delray Beach.

Their best result at a major came at Roland Garros, where they made the semi-finals behind four straight-sets victories, including a quarter-final win against fellow Turin qualifiers Heliovaara and Patten. The Americans also made semi-finals in Indian Wells, Madrid and Tokyo.

Krawietz and Puetz will defend their title at Inalpi Arena, with 2024 finalists Arevalo and Pavic also in the field.
