Raducanu has already made encouraging progress this year to return to the top 40, following a 2024 season which she began ranked 303rd following surgery on both wrists and her left ankle.
The continuation of her positive trajectory has been aided by the addition of former British number one Mark Petchey to her coaching team since March.
Technical work on Raducanu's serve and forehand, as well as a push towards a more aggressive approach, have been among their key areas of focus.
That was all evident here in a statement success.
Despite her own injury issues, Vondrousova had proved a serious threat on grass by defeating five top-50 players, including Sabalenka, at the Berlin Open to lift her first title in 24 months.
But she was thoroughly outclassed by Raducanu, who had lost their previous two meetings, and the Briton will now prepare for the ultimate test of her progress on Friday.
