De Groot completes wheelchair Golden Slam
Diede de Groot has completed the first Golden Slam in wheelchair tennis.
De Groot beat Yui Jamiji of Japan 6-3, 6-2 to win the U.S. Open wheelchair women's singles title.
The No. 1 seed from the Netherlands added that title to her victories this year at the Australian Open, French Open and Wimbledon, along with the gold medal she won earlier this month in the Paralympics.
She is the first tennis player to win all four major titles plus a gold medal in the same year since Steffi Graf in 1988.
Dylan Alcott of Australia was trying to duplicate the feat on the men's side later Sunday.
