Sonay Kartal impressed on debut to give Great Britain a 1-0 lead over Germany in Billie Jean King Cup qualifying.
Kartal weathered the big-hitting of an emotional Jule Niemeier to win 6-4 6-2 in the Netherlands.
World number 60 Kartal looked comfortable on the clay, moving well and often beating Niemeier in exchanges from the back of the court.
British number one Katie Boulter will look to seal the tie for GB when she faces Tatjana Maria in the second singles match, before Olivia Nicholls and Harriet Dart play Laura Siegemund and Anna-Lena Friedsam in the doubles.
