Ekaterina Alexandrova beat top seed Aryna Sabalenka in straight sets in The Rosmalen Grass Court Championship final on Sunday to claim her second career title.
The world number 30 prevailed 7-5 6-0 against a below-par Sabalenka in just 77 minutes to add to her Shenzhen Open triumph from January 2020.
Sabalenka was seeking an 11th singles title and looked value to do so after cruising into the final in 's-Hertogenbosch, but she was outclassed by Alexandrova.
The pair had dropped just one set apiece in their four matches en route to the final, which went the way of the serve until the sixth game when Sabalenka broke her opponent.
However, she was unable to build on that advantage as Alexandrova hit back in the following game and broke the Belarusian again in the 11th to serve out the opener.
In the first meeting between the pair on grass, Alexandrova completely dominated the second set as she broke all three of Sabalenka's service games in a ruthless showing.
The 27-year-old, who had lost two of her previous three finals, took her second match point to complete the job in a stress-free manner.
