Wimbledon 2015: 2nd Monday Schedule and Predictions for All England Club Bracket

Wimbledon's two No. 2 seeds, Roger Federer and Petra Kvitova, were in third-round action Saturday at the All England Club, but only one successfully advanced to the Round of 16.

While Federer took care of Sam Groth in four sets, Kvitova was shockingly upset by No. 28 Jelena Jankovic. The underdog came back strong after dropping the first set to edge Kvitova in three sets. The result came as a surprise due to the fact that the No. 2 seed dropped just three games in her previous two matches, while Jankovic was pushed to the brink by lesser opposition.

The potential of more upsets will only increase going forward, as the Round of 16 boasts a bevy of matchups that should produce nail-biting moments and edge-of-your-seat action. Things will get back underway Monday after a day of rest, so before we delve into some predictions for the day's most notable contests, be sure to take a glance at the updated tournament schedule and order of play.

Novak Djokovic continues to play an unstoppable brand of tennis, as the world No. 1 has yet to drop a set through three matches at the All England Club. He faced off against his first ranked opponent, No. 27 Bernard Tomic, on Friday and breezed through the match in an hour-and-a-half, winning 6-3, 6-3, 6-3.

The consistency throughout Djokovic's game is extremely impressive. Against Tomic, he won 81 percent of his first-serve points, 41 percent of his receiving points and 18 of a possible 23 net points while accumulating 15 aces, 38 winners and only 12 unforced errors.

Djokovic was extremely focused throughout the match—most notably when he found himself behind in a game—and he shared his thoughts on the matter during a press conference, via Wimbledon.com:

"

Well, I just I guess try to get extra concentrated in those moments when I'm down Love-30 or a breakpoint. Obviously I know the importance of holding your serve on the grass court. It's not easy to break players like Bernard, who have a good serve.

I managed to get a lot of returns back in play. I think I executed tactically everything I intended before the match to move him around the court, mix up the pace, not really give him the same look. I think overall I played a really, really good match.

"

The No. 1 seed will need similar concentration against the hard-hitting Kevin Anderson, who recently defeated No. 24 Leonardo Mayer with a brilliant serve. In that match, Anderson won a remarkable 87 percent of his first-serve points and tallied 22 aces. He was incredibly efficient, accumulating just 11 unforced errors throughout the match.

While Anderson's big serve will test Djokovic on Monday, it's difficult to see the No. 1 seed drop a set due to his spectacular return play. Expect Djokovic's winning streak to continue.

Prediction: Djokovic wins in three sets

(1) Serena Williams vs. (16) Venus Williams

This is a match that will be generating plenty of headlines. World No. 1 Serena Williams received her first scare of the tournament Friday, as she was pushed to the brink by Heather Watson only to emerge victorious by a score of 6-2, 4-6, 7-5. Meanwhile, Venus Williams has been playing inspired tennis at the All England Club and has yet to drop a set.

The No. 1 seed breezed through her first two opponents but was highly tested by Watson. Serena began strong, taking the first set with ease; however, she fell flat soon after and struggled to win points off her second serve. Mishit shots and unforced errors began to accumulate until she rallied in the third set with a strong serve and resilience on the volley.

Serena's victory earned her a trip to the Round of 16 where she'll face her sister Venus. She briefly spoke of the impending meeting during a press conference, via Wimbledon.com:

"

Well, you know, it's unfortunate that it's so soon. But we're going to do the best that we can. I mean, she's my sister today. She's my sister next week. She's my sister next year. I think that's a little more important than a match. We'll leave everything out on the court. When it's done, you know, we'll go back to regular life.

"

As for Venus, she's remained very consistent so far at Wimbledon. She's been serving well and picking her spots to approach the net and get aggressive. That led to a smooth outing against Aleksandra Krunic in Round 3, as Venus won 85 percent of her first-serve points, 45 percent of receiving points and 21 of a possible 29 net points while accumulating 21 winners.

The only less-than-spectacular aspect of Venus' game was her unforced errors, as she tallied 16 against Krunic, who isn't known for a big serve or pinpoint accuracy. We should expect Venus to give her sister a run for her money, but those unforced errors will result in another win for Serena.

Prediction: Serena wins in three sets

(4) Stan Wawrinka vs. (16) David Goffin

Stan Wawrinka has been playing some stellar tennis on the grass at the All England Club. He has yet to drop a set through three matches and only appears to be getting stronger as time goes on. He's coming off an impressive showing against Fernando Verdasco, in which he dominated every single aspect of the match from start to finish.

Against Verdasco, the No. 4 seed showcased his blistering serve, winning 87 percent of his first-serve points and accumulating 14 aces. His opponent had very little success against Wawrinka's well-placed services, winning just 25 percent of his receiving points. Combined with his solid defense and success near the net, Wawrinka was nearly unstoppable.

After the match, Wawrinka spoke about the state of his game at Wimbledon during a press conference, via Wimbledon.com:

"

I have the results so far. Three sets each match. That's why I'm saying it's perfect matches. In Grand Slams, you have to win and to win in three sets, it's great. Playing better and better. Serving really well since the beginning of the tournament, being really aggressive. Start to feel more comfortable for moving and in defense also. No, today was really solid match. I'm really happy with the match today.

"

Interestingly enough, David Goffin has yet to drop a set at the All England Club as well. Something has to give. 

Goffin is coming off an impressive showing against Marcos Baghdatis, in which he won 87 percent of his first-serve points, 46 percent of his receiving points and 13 of a possible 19 net points while accumulating 31 winners and seven aces. However, he did struggle with accuracy at times, recording seven double faults and racking up 18 unforced errors.

Both Goffin and Wawrinka can be a little erratic at times, but the difference-maker in this impending contest will be the No. 4 seed's ability to control a match with his dominating serve. That aspect of his game will be enough to put him through to the quarterfinals.

Prediction: Wawrinka wins in four sets
