WASHINGTON - Ameircan star Simone Biles won her fourth world women's all-around title with 57.491 points at the ongoing world gymnastics championships on Thursday.

Japan's Mai Murakami took silver with 55.798 points, while Biles' teammate and defending world all-around champion Morgan Hurd was third with 55.732 points.

With the win, Biles now has four world all-around titles dating back to 2013, and also has a combined 21 Olympic or world medals. The 21-year-old athlete will have four more opportunities to win world titles in Doha, and she'll be the favorite on three of those events.
