Maria Lourdes Carle made a splash at the Madrid Open on Wednesday, as the qualifier sent Emma Raducanu packing.
World number 82 Carle stepped into the void to fill in for Karolina Pliskova, who withdrew prior to the end of the qualifying rounds, to face 2021 US Open champion Raducanu.
It is just the second time Carle has reached the main draw of a WTA 1000 event, and she ensured it would be a memorable campaign after a 6-2 6-2 victory over Raducanu, who is now ranked at world number 221, though has enjoyed something of a return to form this season.
Raducanu reached the quarter-finals of the Stuttgart Grand Prix last week, going down to world number one Iga Swiatek, but has recently enjoyed victories over the likes of Angelique Kerber and Caroline Garcia.
