A full brother to Group III winner Stampede, Think' Big was an unlucky third at his last run in the Group I ATC Spring Champion Stakes, but more than made amends in this 2000 metre assignment.
Perfectly rated in front by Tim Clark, he powered away from his overmatched rivals to win as he pleased by a widening three lengths taking his overall record to four wins from six starts with prizemoney in excess of $480,000.
"He's a lovely horse," said Tim Clark.
"He's so easy to do anything with and for his first go at Caulfield he handled it so well. His attitude is his best attribute, he just wants to work with you."
Thinkin' Big was bred and retained to race by Peter Dunn of Dodmark Thoroughbreds and was foaled at Coolmore.
He still holds an entry for the Melbourne Cup with his co-trainer Gai Waterhouse keen to wait and see how he comes out of this race before making any decisions.
"He'll stay all day," she said.
"On his dam's side he's from the family of Nothin' Leica Dane and he is so much like him."
Waterhouse trained Nothin' Leica Dane to win the Caulfield Classic (Norman Robinson Stakes) in 1995 before he went on to win the Victoria Derby and then finish second in the Melbourne Cup won by Doriemus.
Thinkin' Big is the second winner for classy Tale of the Cat (USA) staying filly Nothin Leica Cat, who was second in the Group I BRC Queensland Oak and is from a half-sister to Group II winner I Am a Ripper.
Nothin' Leica Cat has a yearling filly by So You Think and has foaled this spring producing a colt by American Pharoah (USA).
