Venus Williams competes at Wimbledon on July 4, 2018 in London. 

 

Some of the top American tennis players continue to march forward at Wimbledon, with both Serena Williams and Venus Williams, Madison Keys, John Isner and Sam Querrey among the seven who are still in the hunt after two rounds. 

One more may still join them.

Serena Williams, owner of seven Wimbledon titles and four Olympic gold medals, needed just over an hour to move past Bulgarian qualifier Viktoriya Tomova, 6-1, 6-4, and advance to the third round. Williams is still on the comeback trail after taking time off for the birth of her first child, Alexis Olympia. She played her first Grand Slam in more than a year at the French Open at the beginning of June, but withdrew before her fourth-round match against Maria Sharapova because of a pectoral injury. 

For Venus Williams, seeded ninth, it’s her best Grand Slam performance of the season so far. The five-time Wimbledon champion and five-time Olympic medalist, who lost in the final last year against Garbine Muguruza, had to fight back after losing the first set to Romanian qualifier Alexandra Dulgheru and advanced with a 4-6, 6-0, 6-1 victory. 

Keys, seeded 10th, dispatched qualifier Luksika Kumkhum, of Thailand, 6-4, 6-3. Keys made it to the quarterfinals at Wimbledon in 2015. 

Ninth-seeded John Isner hit 64 aces and defeated Germany’s Ruben Bemelmans, 6-1, 6-4, 6-7 (6), 6-7 (3), 7-5, on Wednesday. This is the third time the Greensboro, North Carolina, native has advanced to the third round at Wimbledon and is looking to make it through for the first time. His next opponent is Radu Albot of Moldova.

Sam Querrey, who defeated defending champion Andy Murray to reach his first Grand Slam semifinal at Wimbledon last year, got past Sergiy Stahovsky, of the Ukraine, 7-6 (4), 6-3, 6-3 to advance to the third round for the third year in a row. He’ll face France’s Gael Monfils next. 

Mackenzie McDonald defeated Nicolas Jarry, 7-6, 5-7, 3-6, 6-2, 11-9, to make it to Wimbledon’s third round for the first time in his career. He’s set to face unseeded Argentinian Guido Pella, who upset No. 3 Marin Cilic in the second round.

Frances Tiafoe rebounded after dropping the first set to Julien Benneteau to win, 4-6, 6-3, 6-4, 6-2. He moves on to face Karen Khachanov in the third round, representing the 20-year-old’s best career performance at a Grand Slam tournament.

A big potential upset was put on hold when 20-year-old sensation Taylor Fritz’s match against No. 4 seed Alexander Zverev was suspended due to darkness with Fritz up two sets to one. It will resume on Friday.
