Wimbledon 2013 Results: Most Surprising Results from Day 5's Early Matches

Wimbledon 2013 has already lost a lot of its stars, and Day 5's early matches continued the tournament's trend as more top players continued to have a hard time getting to the next round.

There weren't many major upsets early on Day 5, but it was by no means easy for the top seeds.

Roger Federer, Rafael Nadal and Maria Sharapova have all been knocked out. The rest of the field needs to take advantage of a depleted field.

The men's No. 2 seed, Andy Murray, will be put to the test later on Friday, and he needs to be ready to go given the tournament's crazy results. 

Let's take a look at some of the surprising results from Day 5 at Wimbledon.

No. 4 David Ferrer (ESP) battles through four sets

Given the upsets through the first four days, it may be more of a surprise that David Ferrer was able to advance to the next round. Ferrer was able to defeat Roberto Bautista Agut (ESP) in four sets, but he had to battle throughout the match.

Ferrer won the match 6-3, 3-6, 7-6, 7-5 (statistics courtesy of Wimbledon's official website). The first set was easy, but the next three were challenging. Bautista Agut was able to win the second set and push Ferrer in each of the final two sets.

The stats were pretty similar throughout the match. Ferrer's 28 unforced errors were only two fewer than his opponent, and Ferrer won 141 of the 273 points in the match. 

Ferrer had four double faults, compared to only one by Bautista Agut, but he was able to make up for it by winning 76 percent of his first serves. Bautista Agut won only 62 percent of his first serves, which made it tough for him to pull off the upset.

The No. 4 seed was able to push through and win the match, but he's going to have to play better if he's going to advance to the semifinals at Wimbledon for the first time in his career.

Down goes No. 7 Angelique Kerber

Like many top seeds before her, Angelique Kerber (GER) lost early in the tournament. Kaia Kanepi (EST) won 3-6, 7-6, 6-3, with statistics courtesy of Wimbledon's official website.

This was a crazy statistical match. Kerber won the total number of points 95-91, and she committed only 17 unforced errors compared to 27 by Kanepi. Kerber didn't have a set in which she had more unforced errors than her opponent.

Kerber won only 29 percent of her second serves in the third set, which would explain how she was finally beaten. 

Kanepi moves on to the third round despite nearly every statistic going against her. It's been a crazy tournament, so a match like this just adds to the list.

No. 24 Jerzy Janowicz defeats No. 15 Nicolas Almagro in straight sets

Jerzy Janowicz (POL) took down Nicolas Almagro (ESP), which wasn't a huge shocker. Beating him in straight sets is what made it so surprising. Janowicz won 7-6, 6-3, 6-4, with statistics courtesy of Wimbledon's official website.

Almagro was dominated in nearly every category. Janowicz won the aces battle 30-18, 59-32 in winners and 109-85 in total points.

A big reason Almagro lost was his struggles on his second serve. He won only 27 percent of the points on his second serve.

Janowicz, on the other hand, won 87 percent of his first serves. He was on top of his game and made it through the third round relatively easy.
