AMERICAN SUCCESS STORIES ON DAY 5
 Madison Keys was given a scare by Naomi Osaka (JPN). Osaka served twice for the match but could not close it out. Down 2-5 in the third, Keys elevated her game, cut down on her errors and broke back twice to even the match. Osaka finally held serve to force a tiebreak; however, the damage was done and she could not recover her equilibrium. Keys showed us her determination as she clawed her way back to victory. She won 7-5, 4-6, 7-6(3).
 Jack Sock backed up his performance from Portland earlier this year, where he came all the way back from two sets down to defeat  Marin Cilic (CRO). Today it was much more straightforward, he won 6-4, 6-3, 6-3
A. Muhammad/T. Townsend defeated  K. Bertens/J. Larsson 6-4, 6-4
HOW THE SEEDS FARED ON DAY 5
After a questionable performance in his first round match,  Novak Djokovic (SRB) has not had to do much to get to the fourth round.
