The Serbian tennis player succumbed in a marathon match against Navone after suffering from physical issues since the first set.
The American tennis player believes that the Spanish tennis player may have doubts when hitting the ball due to his wrist injury, although he trusts that he will do well in New York.
The former world number one believes that the Spanish tennis player has hit the mark by playing mixed doubles alongside the American to feel some extra pressure following his return.
The duo formed by the Italian tennis player and the Swiss showed great strength in their serve and did not give opportunities to the Spanish and the American, who were far from their best version.
After defeating the duo formed by Erin Routliffe and Lloyd Glasspool in their debut, the pair consisting of the Spaniard and the American will step onto the court once again to try to reach the semifinals.
