Jockey Gerardo Corrales thought he has a win on Enders Cat, only to discover he'd sprinted home a lap early.

As Gerardo Corrales rounded the corner on Enders Cat in the sixth race at Florida's Gulfstream Park, he thought he was about to streak clear for the win.

Corrales had negotiated the rest of the field to edge into the lead, then it was time to put the foot down and sprint for the finish.

Only problem - Corrales was a lap early.

Fairfax NZ Things don't get much worse in racing than streaking clear a lap early.

It's about as bad as it can get for a jockey. Crossing the finish line eight lengths clear of his nearest rival, Corrales soon let off thinking he had the race win.

Instead, the field quickly caught up and overtook Corrales and Enders Cat, leaving him languishing in last place when the real finish came around.

The announcer sounded particularly sorry for the jockey, saying "I don't think the rider really knows they are going around again" as he pulled clear.
