French Open 2012: Live Stream; Where To Watch Federer, Djokovic And More In Sunday?s 4th Round Action, Plus Preview

When and where: Day eight's action at Roland Garros gets underway at 5.a.m. ET on the Tennis Channel, before switching to NBC at 1 p.m. A live stream will be available throughout the day on TennisChannel.com.

Preview: With just 16 players remaining in both the men's and women's fields, the French Open shifts up in gears on Sunday.

The highlight of the day for many will be seeing lucky loser David Goffin take on the legend that is Roger Federer. Goffin, just 21 and looking barely half that age, had never played in the main draw of a grand slam before and has surprised perhaps even himself by his progress into round four at Roland Garros.

Hailing from neighboring Belgium, Goffin can expect to receive a great deal of support on Court Suzanne Lenglen, but his stunning run is surely primed to end at the hands of the Swiss.

It is hard to see fellow contender Novak Djokovic being unduly tested, either, when the Serb goes up against 22nd seed Andreas Seppi. The Italian is currently at his career high ranking and even won a title on clay in Belgrade last month, but a 7-0 record against the world No.1 makes for daunting reading.

On paper the most engaging men's match of the day looks to be seventh seed Tomas Berdych's encounter with former US Open champion Juan Martin Del Potro. Both men have a forehand that ranks among the biggest in the sport, meaning it could be an explosive encounter in the last match of the day on Lenglen.

While ninth-seeded Del Potro holds a narrow 3-2 head-to-head advantage, it was Berdych who came out on top the last time the pair met, on clay, last month in Madrid. Though it did take two tiebreaks for him to do so.

American hopes are continued on day eight in the form of 19-year-old Sloane Stephens. Already having achieved her best ever grand slam result to date, Stephens will have to achieve another first if she is to progress past the fourth round. Having never beaten a top 10 player, the Florida-native takes on sixth seed and defending US Open champion Sam Stosur.

Women's No.1 Victoria Azarenka will also be in fourth-round action on Sunday, and may not have things all her own way against 15th seed Dominika Cibulkova. While Azarenka has won seven of the eight encounters between the pair, the pocket-rocket Slovakian gave her an almighty scare the last time the two faced off.

6-1, 4-0 down in Miami earlier this year, Azarenka somehow turned things around to maintain her then unbeaten start to 2012. Given that Cibulkova has dropped just eight games in her three matches so far in Paris, things could again get interesting.
