Top 5 Photos, August 30: "McGauff" packs stands; Stan's souvenir

It was a perfect day for tennis in New York, as notable champions eased their way into the second week and budding stars continued to shine. These are the Top 5 photos from Day 5 at the US Open.

1. A wild card tandem had a packed crowd watching their Court 5 match, with some fans waiting over an hour to grab a seat. Teenage sensations Cori "Coco" Gauff and Caty McNally rallied back from a 2-6 first set tiebreak deficit to take the set and defeat Katerina Siniakova and Julia Goerges, 7-6 (6), 6-2. The pair recently claimed their first WTA doubles title in Washington D.C. earlier this month.

2. Alex de Minaur held a 0-11 record against Top 10 opponents, but on Friday the Aussie came out determined to change that. In an almost three-hour battle, De Minaur defeated No. 7 seed Kei Nishikori, 6-2, 6-4, 2-6, 6-3, to advance into the second week of a Grand Slam for the first time. The 20-year-old is peaking during the hard-court swing, having snatched his second ATP title last month in Atlanta.

3. There were a few minor hiccups along the way, mainly fighting inconsistency on her first serve, but Serena Williams managed to find her rhythm on the ground to roll past Karolina Muchova, 6-3, 6-2. The 23-time Grand Slam champion clinched her 18th consecutive round of 16 appearance in New York and will next meet world No. 22 Petra Martic for the first time.

4.After former NBA superstar Kobe Bryant helped with the pre-match coin toss, Roger Federer needed only 80 minutes to shake hands at the net with Dan Evans. The 20-time Grand Slam champion picked apart the Brit's game to post a dominating 6-2, 6-1, 6-2 victory on Arthur Ashe Stadium. The Swiss star boosted his head-to-head lead to 3-0 and is now 18-0 in third-round matches at the US Open.

5. Stan Wawrinka was frustrated with his play in the first set, and treated a fan to a memorable souvenir before regaining his composure to pull out a 6-4, 7-6 (9), 7-6 (4) victory over lucky loser Paolo Lorenzi. This marked Wawrinka's first time reaching the fourth round since he won the event, defeating Novak Djokovic in the 2016 final. Wawrinka is looking to capture his first title of the season.
