Andy plays Marin Cilic in the final of the Cinci 1000 tonight. A win will see the gap in the rankings between him and Novak decreases by another 1,240 points. After tonight he will have more than double the rankings points of anyone below him, amazing considering he's played less tournaments than anyone else in the top 50 this season.
Great chance to be number 1 soon as Novak is defending the US Open, Beijing, Shanghai, Paris and the World Tour Finals. Andy is defending hardly any points, especially at the US Open where he only reached the last 16 in 2015.
