Wimbledon 2015: Matches to Watch on Day 4

There will be plenty of star power on the court on Day 4 of Wimbledon, with No. 2 Roger Federer, No. 3 Andy Murray and No. 10 Rafael Nadal each competing on the men's side, while second-seeded Petra Kvitova attempts to justify her high ranking.

One could only imagine that Nadal feels slighted about having a double-digit number next to his name, but he'll take Centre Court on Thursday morning, where he can show the world he's still one of the best in the sport.

Nadal will take on Dustin Brown from Germany, whom the Spaniard knows all too well.

In the second round of last year's Gerry Weber Open, Nadal—just coming off his fifth consecutive French Open title—shockingly lost to Brown in their only matchup to date.

Nadal had little trouble against Thomaz Bellucci, beating the Brazilian 6-4, 6-2, 6-4 in the first round, while Brown dropped just one set against Yen-Hsun Lu in his first match.

That sets up a rematch between Nadal and Brown, and reading into what he told the Glasgow Evening Times, Nadal is expecting a hard-fought match:

"

It is difficult to think about how the match is going to be. He's not a usual player. Anything can happen. He beat me last in Halle. It is a dangerous match. He's a tough player... He will probably come with good confidence. I'm going to try to be ready for it.

"

It's tough to see Nadal losing to Brown again, but we'll find out Thursday at 12:30 p.m. ET.

Like Nadal, Federer will also play on Centre Court on Day 4. At 10 a.m. ET, he'll match up against American Sam Querrey, who can take some of the spotlight away from the U.S. women's national soccer team if he can pull off the upset.

Federer and Querrey each won in straight sets on Tuesday, beating Damir Dzumhur and Igor Sijsling, respectively.

Though he doesn't have as impressive a resume as Federer, Querrey has enjoyed some success in his career, advancing to the round of 16 at Wimbledon in 2010 and earning seven career singles titles, including a win in the final of the Queen's Club over Andy Roddick in 2010. 

Despite dealing with numerous injuries over the years, Querrey is ranked No. 36 in the world, according to the ATP World Tour.

To make this a competitive match against Federer, he must use his impressive first serve to set the tempo and try to force Federer to adjust, but that's unlikely to make a difference against the No. 2 player in the tournament.

Murray will go up against Robin Haase at 8 a.m. ET as he looks to win his second Wimbledon title in three years.

He beat Mikhail Kukushkin in straight sets in Round 1, while Haase needed four sets to beat Alejandro Falla in his opening match.

The two have squared off three times before, and Murray has won each matchup.

In a match preview with Cara Robinson, Mats Wilander said he believes Haase needs to pressure Murray into using his forehand in order to stay in this match. Wilander also made note of Murray's more aggressive style of play of late:

ESPN's Patrick McEnroe has picked Murray to win the tournament, and while that remains to be seen, he should have no issues advancing to the third round. 

In women's play, Kvitova—the reigning Wimbledon champion—matches up against Kurumi Nara of Japan at 10:30 a.m. ET, while No. 5 Caroline Wozniacki faces Denisa Allertova at 6:30 a.m. 

Kvitova made quick work of Kiki Bertens on Tuesday, underscoring the idea that she lives for big stages like Wimbledon:

Nara can stun everyone with an unlikely win over one of the best players in the sport, but don't count on it.

Wozniacki—who beat Kvitova in the WTA Finals last year—needs to remind the tennis world that she can make a run at this thing.

She did what she had to do against Saisai Zheng in Round 1, and now it's on to Allertova. If Wozniacki hopes to be taken seriously as a threat to win the tournament, she can't just squeak by in these matches—she has to dominate.

Her boyfriend knows a thing or two about dominating:

Thursday's slate of matches promises to keep tennis fans entertained. 

Plenty of the game's biggest names will take the court, but don't expect any astonishing outcomes.
