Rosie Napravnik, one of North America's leading jockeys, and Lisa Allpress, the best female jockey that New Zealand has ever produced, will join Hayley Turner on the Girls Team for the 2013 Dubai Duty Free Shergar Cup at Ascot on Saturday 10 August.
Meanwhile Gary Stevens, one of America's greatest ever jockeys, will be joined on the Rest of the World team by Japanese ace Yasunari Iwata, who has won three Japan Cups including the last two on Buena Vista and Gentildonna, and Brazilian star Joao Moreira, who is currently re-rewriting the record books in Singapore.
Napravnik, 25, is currently ranked second in wins and fifth in earnings on the North American leader board.
She finished eighth in the jockeys' earnings lists last year, which was the highest place ever by a female jockey, and she also became the first female jockey to win the prestigious Kentucky Oaks on Believe You Can in 2012 and won the Breeders' Cup Juvenile on Shanghai Bobby.
Allpress, 37 and a mother of two, was the first female to pass 1000 winners in New Zealand.
She won the New Zealand premiership last season with 159 winners after finishing second with 145 winners the year before.
She has ridden over 90 Group and Stakes winners and will take up a three-month contract in Singapore later in the year.
