LOUISVILLE, Ky. (AP) -Jockeys Calvin Borel and Javier Castellano turned the winner's circle at Churchill Downs into an impromptu boxing ring, trading punches moments after the opening race of the Breeders' Cup on Friday afternoon.

Borel charged Castellano shortly after the $500,000 Breeders' Cup Marathon, angry over a dangerous mid-race move that endangered Borel and fellow rider Martin Garcia.

Castellano moved into the path of Romp and Martin Garcia, causing the horse to stumble. Borel and A.U. Miner were jostled as a result. Prince Will I Am later was disqualified in the race won by Eldaafer.

The two jockeys were near the weigh-in station next to the winner's circle when things grew heated.

The 43-year-old Borel pointed a finger at the 33-year-old Castellano. The 5-foot-1, 110-pound Castellano then took a swing at Borel, four inches taller than his rival.

Security officials struggled to separate the two. It took several minutes for the visibly enraged Borel - his eyes bugging out and his face a deep shade of red - to be restrained.

Eventually, Borel's wife, Lisa, and brother Cecil each grabbed an arm and walked the three-time Kentucky Derby winning rider back to the jockeys' room, where he flung off his silks.

``I had pressure outside me,'' Castellano said. ``I went for a hole and they said I took his lane. I don't know. I don't know.''

Castellano returned to the track minutes later to ride in the Juvenile Fillies Turf while Borel remained in the jockeys' room to collect himself.

Prince Will I Am, who finished second behind winner Eldaafer, was disqualified and placed 10th while A.U. Miner was bumped up to third following an inquiry.

Borel was scheduled to ride in the Juvenile Fillies and the Ladies' Classic later Friday afternoon. He was decidedly more relaxed 20 minutes after the fight as TV cameras caught him relaxing in the jockeys' room.
