We will have ROc#1 playing against ROC#2 for the gold medal. Even though Pavly & Rublev are the seeded team, I project Vesnina & Karatsev to win this match.
Novak & Stejanovic will play against Barty & Peers for the bronze medal. General theory in MD is that the pair with stronger woman will be the winning team. Going by that Australia should win this consolation match. Sorry, Novak.
