Do well at a major and it is not just a significant payday, it can also be a huge boost in their ranking.

 Tommy Paul (USA) almost squandered his opportunity. The American had a two sets to love lead over  Grigor Dimitrov (BUL) but lost his focus in the third and fourth set; however, he managed to pull it together in the fifth set tie breaker to get the 6-4, 7-6(6), 3-6, 6-7(3), 7-6(3) victory.
 Tennys Sandgren (USA) almost did the same as his fellow countryman, Paul. He got up two sets to love and almost blew it but managed to right the ship in the fifth set to defeat  Matteo Berrettini (ITA) 7-6(7), 6-4, 4-6, 2-6, 7-5.

Polish eighteen-year-old Swiatek and American fifteen-year-old Gauf are playing tennis at a level way above their age. Swiatek got it done easily in straight sets, but Gauf had a to work a bit harder to secure her second-round victory. How far can they go in the draw?
