Wimbledon 2015: Twitter Reacts to Thursday's Bracket Results, Scores, Winners

Unheralded qualifier Dustin Brown stole the spotlight on Thursday at the 2015 Wimbledon Championships with an upset of Rafael Nadal. The German veteran was the better player throughout, which is the latest troubling sign for his Spanish opponent.

A few of Nadal's "Big Four" counterparts, Roger Federer and Andy Murray, were able to advance in straight sets in the other marquee matches on the men's side. No. 2 women's seed Petra Kvitova also had a routine outing as she bolsters her case as a potentially serious threat to Serena Williams.

Let's check out the complete list of singles results from Day 4 at the All England Club. That's followed by some of the reaction to Thursday's action.

Day 4 Reaction

Brown deserves full credit for his performance to send Nadal packing. He came out firing on all cylinders, knowing being the aggressor was his only chance, and he never allowed the 14-time major champion to find a rhythm.

That said, the biggest talking points from the match will surround Nadal. He now hasn't advanced beyond the quarterfinals of a Grand Slam since last year's French Open and has been knocked out of Wimbledon before the third round three times in the past four years.

He hasn't showcased the same explosiveness recently, which takes away from his usually outstanding defense. Taking some time off could help reinvigorate him but, as Howard Bryant of ESPN pointed out, he lost more than a match today:

Before Nadal found himself heading home early once again, both Federer and Murray showcased terrific form in easy victories.

Federer is flashing a vintage level of play through the first couple rounds. He's moved around the court extraordinarily well, been consistent off both wings and simply outclassed opponents in Damir Dzumhur and Sam Querrey, who actually played solid tennis.

Querrey wasn't sure there was anything more he could do on Thursday, as noted by Jon Wertheim of Sports Illustrated:

Murray also pushed through his first two matches without any unnecessary drama. He was particularly impressive today as he dropped just six games en route to knocking out Robin Haase, the 78th-ranked player in the world.

Gary Lineker of the BBC joked about the No. 3 seed's title chances:

Tomas Berdych was the other top-10 men's seed to advance on Day 4. The draw didn't do him any favors, with French veterans Jeremy Chardy and Nicolas Mahut as his first two foes, but they weren't able to derail his title hopes.

As usual, he's moving through the draw without much hype, as the other top players get most of the attention. Joshua Hall of BBC Sport noted the Czech star's ability to fly under the radar:

On the women's side, it's hard to consider anybody other than Williams the favorite after she captured the season's first two majors. But Kvitova, who's a two-time Wimbledon champ, has certainly played just as well, if not better, through two rounds.

She lost just three total games to Kiki Bertens and Kurumi Nara. Getting off the court quickly will allow her to save some energy for the later rounds, and that's exactly what she's done, as highlighted by Christopher Clarey of the New York Times:

Caroline Wozniacki doesn't have a great track record at Wimbledon as a pro. She won the junior title at the All England Club but hasn't advanced beyond the fourth round in the main draw. Two more victories would bring that drought to an end after a strong start to this year's event.

She's beat Zheng Saisai and Denisa Allertova without dropping a set. But the level of competition is going to increase significantly starting with Camila Giorgi in Round 3, so she must avoid lapses like the one late in her match against Allertova, as noted by Ben Rothenberg of the New York Times:

Agnieszka Radwanska, who's slid down to the No. 13 seed after previously reaching as high as No. 2 in the world, is another player to watch in the bottom half. She reached the Wimbledon final in 2012 and has posted her best major results in the event.

Matt Cronin of Tennis Reporters provided her thoughts after beating Ajla Tomljanovic:

Then there's American Madison Keys, a sleeper with a powerful game that should allow her to make a lot of noise on grass both now and in the future. She hasn't played her best tennis yet, but the fact she's been able to advance anyway is a positive sign.

Her section of the draw has also opened up, which is something Tennis Now illustrated:

Looking ahead to Day 5, the action should really begin to pick up in London. It marks the start of the third round, which means seeded players will now begin facing off with each other to create more intriguing matchups.

Both No. 1 seeds are scheduled to play. Novak Djokovic must square off with dangerous Australian Bernard Tomic while Serena Williams is set to battle Heather Watson, who will surely have plenty of support from the home crowd.

Other notable matches on Friday include Maria Sharapova against Irina-Camelia Begu, Milos Raonic facing off with Nick Kyrgios in what should be a terrific display of power and Marin Cilic challenging John Isner in a potential marathon match if both serves are clicking.
