The 22-year-old got off to a flying start on Monday beating fellow Brit Mimi Xu in straight sets 6-3 6-3.
The Brit has been dealt a much tougher test as she takes on 2023 Wimbledon champion Vondrousova.
Raducanu will be last on Centre Court today, as world No1 Aryna Sabalenka kicks things off against Marie Bouzkova before Carlos Alcaraz will hope to avoid an unthinkable upset against British qualifier Oliver Tarvet.
Raducanu vs Vondrousova start time
That means Raducanu is expected on court at around 4.30pm today.
