With most British tennis fans awaiting Andy Murray's next outing on SW19 on Wednesday, all focus is on the women's quarter-finals on Tuesday.
Serena Williams, who suffered a scare against Heather Watson, had a much easier route to the quarter-finals after comfortably beating her sister Venus. She now faces Victoria Azarenka: the pair have met 19 times, with Serena holding a 16-3 advantage. Azarenka is yet to drop a set at SW19 this year.
Elsewhere, Coco Vandeweghe meets Maria Sharapova, with the other ties seeing Madison Keys up against Agnieszka Radwanska, who reached the final of Wimbledon in 2012, and Garbine Muguruza facing Switzerland's Timea Bacsinszky.
Here, James Olley fills you in on all the day's standout events, with play beginning at 13:00 BST on Centre Court and Number One Court.
