You can always rely on America to throw up a horse racing oddity and we were treated to a real head-scratcher at Belmont Park last night.

Race three at Belmont Park looked a fairly nondescript event on paper, with just five runners lining up over the 1700m journey. 

The favourite Highland Sky flew out of the stalls and found himself a length in front after just five metres.

It appeared as though the colt had simply got off to a flyer but a closer look at the start told a different story. 

Highland Sky actually nudged his stall open before the starter had let the rest of the field go, effectively gaining a one-length head start on his rivals. 

Interestingly his jockey elected to restrain Highland Sky, taking a sit just off the leaders. 

Ultimately the head start wasn't enough to get the well-fancied galloper over the line, going down by just under half-a-length in a driving finish. 

Despite Highland Sky seemingly gaining an unfair advantage over the rest of the field, Belmont Park stewards had no problem with the start and correct weight was declared.

While the incident has caused quite a stir on social media, it's fair to say the officials would've come under a bit more heat had the horse won - would they have still declared correct weight?
