Champion mare Black Caviar has drawn barrier three of 10 for her Adelaide debut in Saturday’s Sportingbet Classic.

A sell-out crowd of 30,000 is expected at Morphettville Racecourse to cheer on the world’s highest rated sprinter as she attempts to stretch her winning streak to 20.

Plans for Black Caviar are for two starts in Adelaide before she flies to England to take on Europe’s best in the Diamond Jubilee Stakes at Royal Ascot in June.

The glamour mare is the $1.05 favourite on Saturday.
