The 2014 Kentucky Derby winner leads the field in Saturday's inaugural $12 million Pegasus World Cup at Gulfstream Park. It's the richest horse race in the world.
If California Chrome prevails, he would become the first horse to pass $20 million in career earnings. He will be retired to stud after Saturday.
Also in the field is Arrogate (ARROW-gate), who beat Chrome in last fall's Breeders' Cup Classic.
