An action-packed Wednesday at the US Open is highlighted by the quarterfinal tie between world number three Roger Federer and 11th seed Jo-Wilfried Tsonga.

The constant rain in New York has resulted in all of Tuesday's fixtures being postponed. Therefore, while the top half of the men's draw plays the quarterfinals, the bottom-half will be competing for a place in the quarterfinals. All the women's quarterfinals will also be played out on Wednesday, meaning it will be a long, action-packed day at Flushing Meadows.

In the other quarterfinal, world number one Novak Djokovic will play fellow-Serb Janko Tipsarevic for a place in the semis. It seems a straightforward, especially given Djokovic's form. The same cannot be said of Federer's match against Tsonga.

The two have played each other seven times in total and it'll be there fifth encounter this season. Federer won the initial two meetings, in Doha and Rome, and has won four times overall against Tsonga. However, their last two meetings went the Frenchman's way, the first of which was in the Wimbledon quarterfinals. Tsonga became the first man to defeat Federer after overcoming a two-set deficit. It was a thriller.

Tsonga then proved that the win was no fluke. In the third round of Montreal Masters last month, the 26-year-old defeated the 16-time Grand Slam champion in three sets. He is in a good bit form and has every reason to be confident coming into the game.

Writing off Federer is a risk only a brave, or stupid, man would take. At the age of 30, Federer still displays some tennis. He has looked good in the tournament so far, and booked his place in quarters after an unstoppable victory against Spain's Juan Monaco in just 82 minutes, despite the match ending in the early hours of Tuesday morning.

On the other hand, Tsonga had to play through a tiresome five-setter against American Mardy Fish, and the effects of the strain will be visible as the match progresses. The match will depend on whether how long it takes Federer to find his rhythm and how long Tsonga can last.

When asked about a fifth meeting with Tsonga this year, Federer said he was excited to play with the French showman.

I'm just excited to play against him, to be honest. He said. He's a nice player to watch and so to play against him is very interesting. I thought we had a great match at Wimbledon, which unfortunately I ended up losing. He came back and proved it in Montreal how good he's playing right now. He's definitely on a good streak, so I hope I can stop him this time.

Federer is attempting to match Ivan Lendl's record of an eighth consecutive appearance in the US Open semifinals and over that his 17th major. Tsonga, on the other hand, is hoping to become the first Frenchman to win a major since 1983.

Prediction - Although saying it's Federer's revenge mission is saying too much, he is expected to win, especially after Tsonga's gruelling encounter against Fish in the fourth-round.
