Can Nishikori and Isner utilize their stroke of luck?
Until mid-October, both Kei Nishikori and John Isner couldn't have imagined qualifying for the ATP Tour Finals. But with del Potro and Rafael Nadal pulling out of the tournament, they were presented an opportunity. Every round-robin win guarantees 200 important points and will help to trim the distance between them and the top players of the pack. The gap between Nishikori and Isner is very slim as well.
The No.9 ranked Japanese leads the American by just 235 points. The Japan No. 1 has to contend with a great of the game and a player in great form, in Roger Federer and Kevin Anderson respectively. Dominic Thiem is no mug with the racquet either.
The American No. 1 who plays in a different group, has the World No. 1 to counter against. Alexander Zverev too, if fit, is a tough proposition and so is Marin Cilic.
For both Isner and Nishikori, It's everything to play for.
