I wouldn't bet against a Spanish victory. Vesnina said today: “I don’t like it when people say: ‘You are going to win, no way that you can lose,’. Spain don’t have big names but they have very solid clay-court players. They are in the final so they won a lot of matches, beat good players and they play at home on their favourite surface. Everything is in their favour.
I think with Kuzy's dodgy form, the court surface and the crowd there's every chance the Russians could slip up.
