Paris 2024 Olympics: Fritz, Paul, Collins earn singles wins; Krajicek/Ram set clash with Alcaraz/Nadal

An action-packed Day 4 of the tennis event at the Paris 2024 Olympics, Team USA continued its march towards the medal rounds with six wins across singles and doubles play.

Danielle Collins advanced to the women's singles quarterfinals, while Taylor Fritz and Tommy Paul progressed to the men's singles third round. Collins also teamed with Desirae Krawczyk to reach the women's doubles second round. Rajeev Ram and Austin Krajicek moved on to the men's doubles quarters, where they will meet Spain's Carlos Alcaraz and Rafael Nadal in a Wednesday showdown, while Coco Gauff and Fritz scored an opening win in mixed doubles. Both Gauff and Emma Navarro suffered defeats in the women's singles third round.

Fritz pulls double duty, stays alive in all three competitions

Fritz went the distance in both of his Day 4 matches, coming through a deciding frame to advance in both singles and mixed doubles. He started his effort with a 6-7(3), 6-3, 6-2 singles win against Great Britain's Jack Draper, then returned to the court for a 6-1, 6-7(6), 10-5 win with Gauff against Argentines Maximo Gonzalez and Nadia Podoroska.

Fritz has now won all four of his Olympic matches this week, having earned an opening men's doubles win with Paul on Monday. After a straight-sets victory against Kazakhstan's Alexander Bublik in the singles first round, Fritz had to battle back Tuesday against an inspired Draper.

"I'm really happy to come out of that," the seventh seed assessed. "I felt like I played pretty good from start to finish, to be honest. His level was incredibly high for a set and a half. He was the better player, I was definitely being outplayed. I just kept telling myself to just do the best I can to stay in it, hang in the match with my serve and just keep gutting these holds out.

Collins becomes first American quarterfinalist

With her 6-0, 4-6, 6-3 win against Colombia's Camila Osorio, Collins became the first American player to reach the quarterfinals at the Paris Olympics. It was her second three-set victory in as many days, after she beat Denmark's Caroline Wozniacki in a deciding set Monday.

"A lot of back and forth. Really tough conditions out here I think for all of us," Collins said of her win against Osorio. "I was happy to get through and beat a tough opponent. It means a lot, these wins and representing your country, it's one of the coolest experiences."

Collins is the last American standing in the women's singles competition after Tuesday defeats for Gauff and Emma Navarro. Gauff was turned back, 7-6(7), 6-2, by Croatia's Donna Vekic, while Navarro fell to China's Zheng Qinwen, 6-7(7), 7-6(4), 6-1.
