WINNING AMERICANS ON DAY 4
 Serena Williams defeated Vania King (USA) 6-3, 6-3
 Venus Williams defeated Julia Goerges (GER) 6-2, 6-3
Varvara Lepchenko defeated  Timea Bacsinszky (SUI) 6-4, 4-6, 6-4
Jared Donaldson defeated Viktor Troicki (SRB) 7-5, 6-3, 6-3
Fritz/T. Paul defeated  D. Nestor/V. Pospisil (CAN) 2-2 (RET)
Muhammad/T. Townsend defeated A. Austin/K. Keegan (USA) 6-2, 6-2
Chirico/A. Riske defeated J. Cako/D. Lao 7-5, 4-6, 6-3
 Feliciano Lopez (ESP) lost to Joao Sousa (POR) 2-6, 4-6, 6-1, 5-7. I expected Lopez to find a way to pull this out; however, too much tennis leading into this final Major of the year may have been his undoing. Of course it did not help that Sousa played brilliantly.
 Samantha Stosur (AUS) lost to Shuai Zhang (CHN) 3-6, 3-6
 Steve Johnson (USA) lost to Juan Martin Del Potro (ARG) 6-7(5), 3-6, 2-6
 Alexander Zverev (GER) lost to Daniel Evans (GBR) 4-6, 4-6, 7-5, 2-6. This was a bit of a surprise. I expected Zverev to go deep. He seems to have lost his way a bit mentally. I hope he can pull it back together as he is such a talent.
 Gilles Simon (FRA) lost to Paolo Lorenzi (ITA) in what has to be a major upset. Lorenzi won 3-6, 6-2, 6-2, 6-7(1), 7-6(3)
American Jared Donaldson continues to be impressive; he got through the qualifying rounds and is making the most of being in the main draw of the US Open. He is into the third round of a Major for the first time in his career. Del Potro continues to defeat players who are ranked much higher than he is ranked at the moment; yet, we know that his current ranking belies his incredible talent and no one wants to play him right now in this form. Next up for him is the eleventh seed, David Ferrer (ESP). Rafael Nadal will be tested again tomorrow night. Despite his winning record against the Russian, Kuznetsov pushed him earlier this year on hard court. American sensation, Catherine Bellis will get to showcase her talents against the number two ranked/seeded player, Angelique Kerber, tomorrow night after Nadal’s match.
