US Open ATP: Marin Cilic v Andrey RublevAndrey Rublev @ 51¢void
US Open ATP: Marin Cilic vs Andrey Rublev RUBLEV ML 51¢ Rublev ML odds moved so much idk why. Rublev was playing expectionally well in his last game (mix doubles) rather than Cilic who seems to be out of shape in previous 2 matches where he collapsed and completely shut down after the 1st sets.
