Soon, he left Maryland to race in New York and New Jersey and at the age of 18 was the United States Champion Jockey by wins with 469.
Then in 1999, Antley returned to ride the D. Wayne Lukas-trained Charismatic, and they won that year's Kentucky Derby and Preakness Stakes.
During the week leading up to the 1999 Belmont Stakes, he was invited to ring the Opening Bell at the New York Stock Exchange.
Shortly after his death, his wife, Natalie Jowett, a former ABC Sports employee, gave birth to their daughter, Violet Grace Antley.
