Wimbledon 2017: Roger Federer, Novak Djokovic Advance with Saturday Wins

Roger Federer and Novak Djokovic both won in straight sets on Centre Court at 2017 Wimbledon on Saturday to qualify for the tournament's fourth round.

Federer beat Mischa Zverev, while Djokovic had too much for Ernests Gulbis. They will be joined in the next round by Milos Raonic and Tomas Berdych, who were also notable winners in the men's bracket.

The women's event saw top seed Angelique Kerber survive a scare against Shelby Rogers, while Agnieszka Radwanska also made it through.

Federer booked his familiar spot in Round 4 in typically comprehensive fashion. He dispatched Zverev in style after outlasting the German in a tiebreak to win the opening set.

Afterward, the 35-year-old said he's feeling good ahead of the second week, per the official Wimbledon Twitter account:

Federer will now face Grigor Dimitrov in the next round, after the 13th seed beat Dudi Sela emphatically in straight sets, dropping just two games en route to victory.

Earlier, Djokovic progressed after beating Gulbis in straight sets. A tiebreak was needed in the third as Gulbis fought bravely to stay in the match, despite being slowed by a back problem during the second set.

However, Djokovic stayed strong to earn the result his accomplished performance merited. The Serb has made a habit of reaching the second week of Wimbledon, per BBC Sport:

Djokovic will now face Adrian Mannarino, who ensured Gael Monfils' dubious distinction of never having reached the second week of Wimbledon goes on.

Mannarino came back brilliantly from 2-1 down to eventually beat his fellow Frenchman in five sets.

Sixth seed Raonic stayed in touch during a tiebreak against Albert Ramos-Vinolas in the first set. Canadian Raonic took the set 7-6 (3), decisively snatching momentum away from Ramos-Vinolas.

From there, it was comfortable stuff for Raonic, who captured the next two sets without too much fuss. As usual, a powerful service game defined Raonic's performance, per the Wimbledon official Twitter account:

Raonic will also be joined in the draw by Tomas Berdych, after the 2010 finalist saw off Spain's David Ferrer in straight sets. Berdych will face Dominic Thiem in the next round after the Swiss player progressed thanks to a straight-sets win over American Jared Donaldson.

There was also an impressive showing from Alexander Zverev, who beat Sebastian Ofner. Precocious 20-year-old German Zverev has been flawless through three rounds:

The day also saw Sam Querrey wrap up his upset win over Jo-Wilfried Tsonga. They had started on Friday, and Querrey finished the job well on Saturday.

As ATP Media Info noted, Querrey's last major upset at Wimbledon stretched over two days:

Over in the WTA, Radwanska ensured a last-16 meeting with Svetlana Kuznetsova but only after she rallied from a set down against Timea Bacsinszky.

Radwanska's meeting with Kuznetsova won't be the marquee matchup of the next round in the women's event, though. Instead, the distinction will belong to world No. 1 Kerber's meeting with Garbine Muguruza.

Like Radwanska, Kerber had to overcome early adversity against 70th-ranked Shelby Rodgers. She dropped the first set 4-6 and had to survive a tiebreak in the second.

As Ben Rothenberg of the New York Times noted, Kerber wasn't playing up to her billing as the WTA's top-ranked player at the tournament:

"

Kerber just isn't playing anything like the tennis that got her to #1. None of the tenacity is there. But she may escape: up 6-5* in second.

However, the German recovered to take the tiebreak 7-6 (2), before a 6-4 win in the third sent Kerber through.

There was an even better comeback when Caroline Wozniacki beat Anett Kontaveit. Wozniacki lost the first set and forced some key breaks of serve to survive in the second before winning 6-2 in the third.

As ESPN's Brad Gilbert noted, Kontaveit should rue the chances she squandered:

Things remain tough to predict in the women's bracket, while familiar contenders such as Djokovic and Federer are returning to their best form in the men's event.
