We're into the fourth round at the 2012 US Open.
The first week has finished (or the second week has started, if we're going to be technically correct) and both the men's and women's draws are seriously starting to heat up.
All the big names in both tournaments are still there, with the likes of Serena Williams, Novak Djokovic and Roger Federer all starting to play their best tennis and make a serious challenge for another Grand Slam crown.
Here's a look at all the action from Sunday—Day 7 of the US Open.
Notable Winners from Day 7
Novak Djokovic, Juan Martin Del Potro, Richard Gasquet, Janko Tipsarevic and Stanislas Wawrinka were all notable winners from Sunday's action—running out straight-sets winners in their respective matches.
Reigning US Open champion Samantha Stosur also booked her place in the quarterfinals—defeating Great Britain's Laura Robson 6-4, 6-4.
Notable Losers from Day 7
Whilst there were no big-name players that made an exit from the tournament on Day 7, there were still plenty of well-known players who were eliminated from the competition, all of whom came from the men's draw.
Seeded players such as Julien Benneteau and Alexandr Dolgopolov both lost their respective matches, with Benneteau losing to Djokovic and Dolgopolov losing to Gasquet in straight sets.
