Juan Sebastián Cabal and Robert Farah were the defending champions from when the tournament was last held in 2019, but lost to Rajeev Ram and Joe Salisbury in the quarterfinals.
Pavić and Nicolas Mahut were in contention for the ATP No. 1 doubles ranking. By winning his first round match, Pavić retained the top ranking.
Because of a delay in schedule due to rain, the first two rounds of the competition were played best-of-three sets instead of the usual best-of-five format.
