A rejuvenated Samadoubt proved his win in the Group 1 Winx Stakes was no fluke with a dominant performance in Saturday's Group II Chelmsford Stakes (1600m) at Randwick.
Tim Clarke let the son of Not A Single Doubt amble to the lead from an outside barrier and he kept up a relentless gallop to stroll home by three and a quarter lengths from the favourite Avilius with the fast-finishing Girl Tuesday a half-head back in third. (images Steve Hart).
"Unless Winx returned, nothing was going to run him down," Clark told AAP.
"He's flying. He was able to control it a bit better today, just at the mile and drawing out wide I was able to take my time and got into a great rhythm.
"He's proved the other day was no fluke and now the great mare has gone, somebody has got to put their hand up as the next weight-for-age horse and, at the moment, he's doing just that."
If trainer Bjorn Baker was surprised by the 6yo geldings win in the Winx Stakes he went in to the Chelmsford with a degree of confidence.
"His work since his first run has been nothing less than sensational and, I say it tongue in cheek, but he's been working like a Group 1 horse," Baker said.
"Going forward, it gives him a lot of options.
"He's nominated for the Caulfield Cup but not the Cox Plate. I was surprised we didn't get a call for the Everest after he won first up."
With just the Listed Canberra Cup to his credit in black-type races before the present preparation, Samadoubt advances his record to 10 wins, 6 seconds and 3 thirds from 36 starts with earnings of $937,510.
A $40,000 purchase by Darby Racing from the Riversdale Farm draft at the 2015 Inglis Classic Yearling Sale, Samadoubt is a three-quarter brother to the Group III placed Thin Red Line and is the best of five winners out of the Gold Fever (USA) mare Isadora who is a half-sister to the Group II VRC Bloodhorse Breeders' Plate winner Apollo Wonder (Rory's Jester).
Isadora died in October last year. Her final foal is a yearling filly by Rothesay.
