Exciting young stallion So You Think has his fourth winner in the past eight days after top Sydney jockey Hugh Bowman piloted the David Pfieffer-trained I Thought So to victory at Randwick on Wednesday.

I Thought So as a yearling

I Thought So ($2.45 fav) was well-found in betting on the Glen Miller Handicap (1200m) after two impressive barrier trials at Warwick Farm last month.

Bowman elected to lead on the colt in a leisurely-run contest before the pair staved off challengers inside and outside over the final stages to score by a short-head.

The Michael Tubman-trained Bye See ($11) finished second, a half neck clear of Ron Leemon's Perfect Rhyme ($31) in third.

Recent wins to So Spirited, Naughty Thoughts and The Pinnacle has So You Think climbing up the second-season sire list and Bowman believes there is a lot more to come from the dual-Cox Plate winner's offspring.

"They're obviously not two-year-olds but now that they're three-year-olds we are starting to see them come through the ranks," Bowman said.

"They're good strong boned horses and are racing very well.

"This horse had been trialling well so he wasn't under the radar but he's certainly got scope.

"He's been looked after as a younger horse and it's starting to show now – he's a nice horse."

I Thought So is out of the stakes placed Cat's Pyjamas (by Fusaichi Pegasus), a sister to multiple Group winner Cats Whisker, the dam of Blue Diamond favourite Catchy.

He was purchased by Pfeiffer for $200,000 out of the Coolmore Stud draft at the Magic Millions Gold Coast Sale.

So You Think has 15 yearlings set to go through the Melbourne Premier Sale starting February 26 and a further 17 entered at Inglis Easter.
