Roger Federer and Serena Williams will be expected to maintain their flawless progress at Wimbledon as the title favourites head into the fourth round looking to survive the tournament's giant-killing carnage on Monday.
But, most importantly, they are fit and healthy at the same time and showing signs that a blockbuster rematch might be on the cards come July 15 as they have both reached the fourth round at the grasscourt championships without dropping a set.
German fourth seed Alexander Zverev and women's world number one Simona Halep wilted in 33-degree heat and crashed out of Wimbledon in the third round on Saturday (Jul 7).
But it's business was usual for Federer as the defending champion took his consecutive sets won at Wimbledon to 29 in a third round dismissal of Germany's Jan-Lennard Struff.
Van Uytvanck will meet Russian 14th seed Daria Kasatkina, who beat Australia's Ashleigh Barty 7-5, 6-3.
Gulbis, a former world number 10 who famously defeated Roger Federer on his way to the French Open semi-finals in 2014, will be playing in the last 16 at Wimbledon for the first time at the 11th attempt.
"Novak and Rafa, all these guys are still in the draw", Federer said.
"I'm not saying that should happen again". I know on the women's side more so. "I didn't feel the effect this time".
With all of the men's and women's last 16 singles ties taking place, it is one of the most exciting days in the tennis calendar. The 19-year-old has improved his strength and is noticeably bigger since his first Grand Slam appearance as a wildcard at the 2017 Australian Open, where he lost to American Sam Querrey in round 2.
She faces another mother in the fourth round Monday (Tuesday NZT): 120th-ranked qualifier Evgeniya Rodina of Russian Federation, who upset No. 10 seed Madison Keys of the U.S.
Seven-time victor Williams, the favourite for the women's title, plays Russian qualifier Evgeniya Rodina.
"Serena is my idol, " Rodina said.
"I had my chances to win here a few years ago". She plays Kiki Bertens first-up on No 2 Court, the victor advancing to the quarter-finals against either Julia Görges or Donna Vekic. Another statistic that makes this one seem like quite a mismatch: Federer is 5-0 against Mannarino, winning 12 of the 13 sets they've played.
The Canadian and his Austrian opponent were forced off by darkness in the third set on Friday night but Raonic, beaten by Andy Murray in the final in 2016, secured a quick break to take the third set before dominating the fourth to win 7-6 (7/5) 4-6 7-5 6-2.
