New Zealand-bred galloper Sansom made it three wins in a row at Sandown on Wednesday when victorious over 1300m.
The son of Charm Spirit jumped away well from gate six to take the early lead for jockey Ben Allen where he was able to dictate terms throughout and go on to win by nearly two lengths.
"It wasn't how I really mapped out the race, I would have liked to have had something to follow, but he was the first one out of the gate, so I thought I may as well take up the lead while he could," Allen said.
"He relaxed beautifully and each time he is stepping out he is improving. It's quite noticeable in his racing."
Trainer Phillip Stokes was pleased with the victory and said Sansom is starting to develop into a nice racehorse.
"We have had to do a lot of work with him. He had been doing things upside down," he said.
"We have been trying to really restrain him, but you just have to let him go out and get his rhythm and he seems happy.
"The track conditions didn't worry him and he put paid to them well.
"I'm in two minds now. I was going to tip him out, I still might, and just see if he can go to something a little bit better down the track."
Stokes purchased Samson for $140,000 at the 2018 Gold
Coast Magic Millions Sale.
