Favourite Orb, ridden by Joel Rosario, won the 139th Kentucky Derby at Churchill Downs on Saturday.

The Shug McGaughey-trained horse flashed past his rivals in the final stretch to win the mile-and-a-quarter classic and the $2m prize.

Outsider Golden Soul finished second and Revolutionary was third.

Orb now has the chance to capture US Flat racing's Triple Crown of the Kentucky Derby, and the Preakness and Belmont Stakes.

The Preakness follows in two weeks and the Belmont Stakes is on 8 June.

On a muddy track, Normandy Invasion had grabbed the lead on the home straight, but Orb stayed in contention to take victory and give Rosario his first Derby win.

Normandy Invasion faded to fourth with Orb finishing in a time of 2:02.89.
