Jessica Kurten chalked up her seventh victory in 15 days with victory in the Mercedes Swiss Masters competition in Zurich.
The 36-year-old rider also collected a Mercedes car for her efforts, to add to the considerable prize money amassed since she won the $250,000 Dubai Grand Prix earlier in the month.
Riding the ten-year-old mare Castle Forbes Libertina, Kurten was one of only two competitors to record double-clear rounds, the other being British runner-up Michael Whitaker.
Kurten rode Quibell to victory in the Swiss Grand Prix on Thursday.
