The men's and women's singles draws are beginning to take shape at the 2013 French Open as fourth-round action begins on Sunday at Roland Garros.
Favorites Serena Williams and Roger Federer headline Day 8's slate. Past champions at the French Open, each is looking to add to their impressive legacy with another win, which would advance them to the quarterfinals of their respective draws.
But Williams and Federer aren't the only two poised to win this weekend.
Here are my predictions for every fourth-round singles match on Sunday.
Roger Federer (2) over Gilles Simon (15)
It's been nine years since Roger Federer failed to reach the quarterfinals of a Grand Slam, so don't expect him to falter on Sunday in the fourth round against Gilles Simon.
Sure, the 15th-seeded Frenchman has been playing high-level tennis in Paris this week, but he's coming up against a player in Fed who has yet to drop a set at Roland Garros this summer.
The Swiss legend has been on the absolute top of his game thus far, winning around 80 percent of his first-serve points for the tournament and not yet recording a single double fault. Simon has upended Federer in the past, but never at a Slam.
David Ferrer (4) over Kevin Anderson (23)
This under-the-radar match between David Ferrer and Kevin Anderson has the potential to not only go the distance, but to steal the show on Day 8 at the French Open.
The world No. 5, Ferrer is coming off of his first-ever run to the semifinals at Roland Garros a year ago, and is among the top clay-court players on the planet. But his 6'8" South African opponent, Kevin Anderson, has some game of his own.
Anderson has dropped just one set through the first three rounds, disposing of 14th-seeded Milos Raonic in straight sets in Round 3. Plus, he beat Ferrer in a three-set match on the hard courts at Indian Wells last March.
Despite that loss, I look for Ferrer to get it done in the fifth and final set on Sunday, advancing to the quarterfinals at the French Open for the fourth time in his career.
Jo-Wilfried Tsonga (6) over Viktor Troicki
Top-ranked Frenchman Jo-Wilfried Tsonga will receive tons of support from the home crowd on Sunday as he looks to take down surprising fourth-round opponent Viktor Troicki, who upset Marin Cilic in the previous round.
Although all players at this stage are in solid form and playing with plenty of confidence, expect Tsonga to cruise through this match. He's winning a very high percentage of first-serve points, he hasn't dropped a set yet and he's owned Troicki on clay as of late.
The two players have met at the Rome Masters twice since 2010, with Tsonga winning both matches in straight sets.
Which men's 4th-round match are you most excited for on Sunday?
Nicolas Almagro (11) over Tommy Robredo (32)
In an all-Spanish affair, three-time French Open quarter-finalist Nicolas Almagro will battle 32nd-seeded Tommy Robredo.
Look for Almagro to win this matchup rather easily on Sunday. The 27-year-old world No. 13 has dropped just one set through his first three matches, winning nine straight since losing the opening set in Round 1. Plus, Robredo is coming off a five-set match against Gael Monfils that required two tiebreaks.
As if you needed any more reason to like the higher seed in this matchup, the 31-year-old Robredo has dropped five straight matches overall to Almagro, including four on clay.
Serena Williams (1) Over Roberta Vinci (15)
Serena Williams has dropped just six games total coming into the fourth round at the French Open on Sunday. The overall top seed in the women's draw, Williams was expected to shine coming into this tournament and she somehow surpassed those lofty expectations with her early dominance.
Considering the unbelievable form the 2002 French Open champ is currently in, you have to love her chances to win easily in straight sets over Roberta Vinci.
Vinci is an accomplished doubles player, but she has never been past the third round at Roland Garros in singles play. Combine that with what Serena is dishing out and you have the recipe for another Williams clinic in Paris.
Agnieszka Radwanska (4) over Ana Ivanovic (14)
Despite her winning the title here in 2008, Ana Ivanovic has a lot to prove on Sunday against fourth-seeded Agnieszka Radwanska.
The 24-year-old Pole has owned the Serb in recent years, winning six straight matches against her, including two on clay in Rome and Stuttgart. Therefore, Radwanska should have plenty of belief that she can win heading into this showdown.
On top of that, if Radwanska is going to take the next step in her career, she's got to do it here. She's lost three times in the fourth round of the French Open since 2008. A berth in the quarterfinals in Paris this weekend would be huge for her development.
Sara Errani (5) over Carla Suarez Navarro (20)
2012 French Open finalist Sara Errrani looks even stronger than she did a year ago, winning all six sets heading into her fourth-round matchup with clay-court specialist Carla Suarez Navarro.
The 26-year-old Italian is a serious contender at Roland Garros this summer and could challenge Serena Williams in a potential semifinal matchup later this week.
Look for Errani to win this match relatively easily. Suarez Navarro reached the quarterfinals at the French Open in 2008, but she has been bounced in the third round twice since 2009. What's more, Errani has won five of the last six meetings with her Spanish rival, including three straight on clay.
Which women's singles match intrigues you the most on Day 8?
Svetlana Kuznetsova over Angelique Kerber (8)
Angelique Kerber, who reached the quarterfinals at Roland Garros for the first time in her career last year, will take on 2009 French Open champion Svetlana Kuznetsova in the fourth round this weekend.
Although Kerber has won the last two meetings between these two, including a matchup on clay in Madrid last month, Kuznetsova no doubt has the championship pedigree to get past the eighth-seeded German, who before last year, hadn't been past the second round in Paris.
Look for this match to go the distance on Sunday, but expect unseeded Kuznetsova to pull off the upset over Kerber, who could easily be caught looking ahead to a potential semifinal clash with Serena Williams in the next round.
