Cockshutt and Cooper purchased Watch This Spot in New Zealand last year for an undisclosed sum and immediately sent him to's stable.
The gelding won a 2YO on debut at Cranbourne and after a minor placing at his subsequent outing at Terang he was dispatched to Tasmanian where he scored an emphatic win in Launceston.
He was shipped straight back to Victoria where he placed at Kilmore before ending his 2YO season with a win at Bendigo,'
Watch This Spot resumed in March with a win at Kilmore and after meting interference in the VHRSC 3YO Cup at Melton he went to Geelong where he finished a game second to Ideal Majority in a 3YO Pace over 2100m.
Braun is quietly confident watch This Spot can emerge triumphant on Sunday.
"This is a very nice horse that is more than capable of winning the Tasmanian Derby," Braun said from Melbourne today.
"I wouldn't be sending him if I didn't think he could win."
"It is likely to be a strong Derby from what I hear but I have a lot of confidence in this horse. He hasn't disappointed me at any stage and provided he travels well I expect him to be hard to beat," he said.
The Derby promises to be one of the best in years with local star Resurgent Spirit aiming to notch his 14th consecutive win and steal the record for the most number of consecutive wins in Tasmania from the great Halwes.
Local 3YO Rusty Red Comet also has been racing in career best form with his win last Sunday night in Launceston testament to his ability to warrant respect in next Sunday night's classic.
