Heavy rain forced the postponement of the $150,000 Sham Stakes for 3-year-olds at Santa Anita.

Track officials said Saturday that heavy overnight and early morning rain was expected to continue throughout the day, causing drainage problems with the synthetic track. However, they are scheduled to rain today.

The Sham will be run March 6, with the field redrawn for the 1 1/16-mile race that is a major prep for the Santa Anita Derby on April 3.
