Alastair Grant/Associated PressOn Saturday, the Wimbledon winner was able to earn his seventh consecutive entry into the second week of London.Roger Federer, eight-time Wimbledon champion, needed four sets in order to defeat Cameron Norrie. He received plenty of support from his home crowd and was able to overcome the fan favorite.Federer was among seven men seeded to reach the fourth round after he won on Saturday. All 16 round-of-16 matches at the All England Lawn Tennis and Croquet Club will be played on Monday.Coco Gauff, in the women's draw has grown in stature on grass courts over her two Wimbledon appearances. With her third consecutive win in a row, the American teenager breezed into round four.Two years ago, Gauff reached the Grand Slam stage after a fourth round run at Wimbledon. On Monday, she will face Angelique Kerber with a chance of clinching her second consecutive Grand Slam quarterfinal.Gauff will be playing in one of five seeded matchups during the women's round 16 but those matches might not get as much attention than the unseeded affair with Emma Raducanu.Raducanu won her third consecutive match in the first Wimbledon main draw, continuing to win over the hearts of the British crowd.Men's singlesNo. 2 Daniil Medvedev def.

Jordan Thompson, 6-1, 6-4 and 6-4Federer mastered the toughest of his first three rounds on Saturday.Norrie is at his best and had the support of Centre Court, who usually aligns with Federer during Swiss plays.Although Norrie was strong in the first two sets of the match, Federer was unable to take a set until the third frame.Federer overcame the challenge of the No. Federer, a 29-seed, won the fourth set by the exact same margin of two games as he won the first two sets.Lorenzo Sonego is Federer's next opponent. Sonego reached the fourth round of a Grand Slam for only the second time in Federer’s career.In 2019, Roland Garros will host one meeting between round-16 opponents. Federer won this match in straight sets.Federer will face a tough path in the next rounds if he defeats Sonego. Alexander Zverev and Matteo Berrettini both performed well in the fourth round. Daniil Medvedev, however, rallied from two sets down to advance.Berrettini won in three sets against Aljaz Bedene, and should be considered a heavy favorite to defeat unseeded Ilya Ivashka.Zverev has a 3-0 head to head advantage over Felix Auger Aliassime. After playing two sets against Nick Kyrgios (injury), the Canadian will feel better.Zverev worked to a fourth-set tiebreak in order to displace American Taylor Fritz, who lost and left Sebastian Korda the only American left in men's draw.Medvedev was on the verge of being eliminated and reached the fourth round against Marin Cilic in this final match.In the third set, the second-seeded Russian gained momentum by defeating Cilic 6-3. To turn the match around, he won four of five final games of the third set.In the fifth set, Medvedev made his comeback with a dominant performance. He won five of the set's first games and was crowned the No. He was 32 on his fourth match point.Medvedev could win one more to set up a quarterfinal matchup with Federer. In the round of 16, he plays Hubert Hurkacz.Singles for WomenNo. No. Katerina Siniakova 6-3, 7-5No. 14 Barbora Krejcikova, def. Anastasija Svastova 7-6 (7-1), 3-3, 7-5No. 19 Karolina Muchova def.

Sorana Cirstea 6-3, 7-5Alja Tomljanovic defeated Jelena Ostapenko 4-6, 6-6, 6-2Through her straight-set win on Saturday, Gauff set up her first-career match against Kerber.The 17-year old has yet to lose a set in London. In 2019, she lost in her first three rounds.Simona Halep eliminated Gauff in 2019, and Kerber will face her this year. Kerber is the most experienced player in the women's game.Kerber was actually one of four Grand Slam winners in the 16-player final of the women's draw. In the second and third sets, she looked every bit a champion against Aliaksandra Ssnovich. In those sets, she outscored Aliaksandra Sasnovich 12-1.Gauff will be able to get past Kerber and make it to the semifinals much easier than when she was drawn. No. Elina Svitolina, 3rd seed, and Anastasia Pavlyuchenkova, French Open runner up were both eliminated from the section above theirs.In the best case scenario, Gauff would meet Ashleigh Barty, top seed in the semifinals. Barty showed great strength in her victory over Katerina Sniakova in two sets.In the round of 16, Barty will face Barbora Krejcikova, winner of the French Open. This could be the match for the round on women's sides.Raducanu and Alja Tomljanovic will be facing the winner of this match. Raducanu was the highlight of the tournament. She won in straight sets for her third round.The 18-year old entered Wimbledon as a wild card and had never played in a Grand Slam singles drawing before.Tomljanovic and Raducanu will be playing in the unseeded match in round 16. Two unseeded round-16 women's matches were held at the French Open, while none at the Australian Open.
