Kei Nishikori vs Phillip Kohlschreiber
Kei Nishikori is just starting to get his groove back after a couple of seasons that have been disrupted by injury and he is well-placed to progress to the US Open Quarter Finals. Nishokori has not lost a set in his two previous matches against Kohlschreiber and he should have too much quality for the consistent German.
Madison Keys vs Dominika Cibulkova
Madison Keys has an excellent record against Dominika Cibulkova and she deserves to go into this US Open clash as clear favourites. Keys has won the four previous matches between the pair and three of those wins have come in straight sets. Keys looks in outstanding form and she should be able to record a comfortable win.
Marin Cilic vs David Goffin
There is nowhere near as much between Marin Cilic and David Goffin as the current market suggests. Cilic was given a genuine scare by Australian Alex de Minaur on Sunday and fitness has always been an issue. Goffin has a superior Hold/Break percentage to Cilic on hard courts and he is excellent value at his current price.
