Emma Raducanu knows full well what it is like to be a little-known qualifier upsetting the odds at a Grand Slam tournament.
On Sunday, the boot will be on the other foot at Wimbledon.
The 21-year-old Briton famously won the US Open as a teenager qualifier three years ago, creating one of the most stunning shocks in sporting history.
Now Raducanu faces New Zealand qualifier Lulu Sun, a 23-year-old who had never played in the Wimbledon main draw until this year.
The pair meet in the fourth round at around 17:00 BST on Centre Court.
