California Chrome's health at issue

— -- Kentucky Derby winner California Chrome was heard coughing after a 1½-mile gallop at Pimlico early Thursday, and trainer Art Sherman told ESPN's Jeannine Edwards that his biggest concern is that the horse will catch a cold.

The forecast calls for rain in Baltimore through Friday morning. Sherman said he plans to train California Chrome on Friday for Saturday's Preakness, as long as the horse is healthy.

California Chrome was made the odds-on favorite at 3-5 on Wednesday for the second leg of horse racing's Triple Crown, and he drew an inside post position in the 10-horse field that includes a filly for the first time in five years.

Ridden by Victor Espinoza, California Chrome will break from the No. 3 post, which has produced 10 winners in the previous 138 runnings of the 1 3/16-mile race, the last being Prairie Bayou in 1993.

California Chrome is being treated with a glycerin throat wash to coat the irritated area, according to Blood-Horse.
