The son of Captain Rio was sent off an 8/1 shot and overcame greeness to score in the hands of Andrea Atzeni.
He was settled towards the rear by Andrea, who allowed the race to unfold ahead of him.
The gaps opened and Andhesontherun showed a smart turn of foot to take the lead inside the closing stages, winning by half a length.
Roger said: "He was a bit green early on but I liked the way he knucked down and he was well on top at the finish."
Andhesontherun was our first runner for owner Ken Gundlach and, in addition to his winner's prizemoney, he also netted a £10,000 Racing Post Yearling Bonus.
