The set then went into a tie-break, in which Karatsev and Vesnina won four consecutive points to take a 4-1 lead before realizing their first set point a few points later. After losing a tight first set, Djokovic and Stojanovic responded well as they broke Karatsev and Vesnina in the opening game of the second set.
But Djokovic and Stojanovic failed to hold on to their serve in the rest of the set as Karatsev and Vesnina broke back in the eighth game.
Tough day for Djokovic
Earlier in the day, Djokovic was up by a set and a break in the singles semifinal before losing to German Alexander Zverev.
In the remaining mixed doubles semifinal, Russia's Andrey Rublev and Anastasia Pavlyuchenkova claimed a tight win over Australia's John Peers and Ashleigh Barty to set up an all-Russian final. Rublev and Pavlyuchenkova recovered from a set down to beat Peers and Barty 6-7 6-4 13-11.
Rublev and Pavlyuchenkova saved a set point in the 10th game of the first set but couldn't do the same two games later as Barty and Peers realized their third set point to win a tight opener. After losing a tight first set, Rublev and Pavlyuchenkova bounced back well as they claimed back-to-back breaks to win five games in a row and take a 5-1 lead.
But Peers and Barty refused to give up, winning the following three games to reduce the deficit to 5-4. However, Rublev and Pavlyuchenkova regrouped in the 10th game as they managed to serve out for a decider. In the match tie-break, Rublev and Pavlyuchenkova saved a match point before realizing their third match point to complete a comeback win.
