Djokovic, Venus Williams at Hopman Cup

Top-ranked men's player Novak Djokovic and seven-time Grand Slam singles champion Venus Williams will represent their countries at the Hopman Cup team tennis tournament, although they won't play each other unless Serbia and the United States advance to the final.
Playing for the first time on blue courts at the new Perth Arena, the eight-country event begins Saturday when Spain plays South Africa and Germany takes on Australia.
Williams and her partner John Isner will see their first action Sunday when the U.S. plays South Africa, and Spain also plays France on the same day. Serbia, represented by Djokovic and Ana Ivanovic, plays Italy on Monday.
Each match consists of women's and men's singles followed by mixed doubles.
