Stakes placed last season in the Listed Gold Coast Bracelet, the Peter and Paul Snowden trained four year-old put the writing on the wall last start with a good second in the Group III ATC Aspiration Stakes at Randwick.
Stepped up to 1900 metres for this assignment, she relished the trip, powering to the line to win by a length and quarter taking her overall record to three wins and seven placings from 11 starts earning over $250,000.
"She has really furnished this time in and deserved that win," Peter Snowden said.
"That was a good performance today.
"I'm not sure where we go now. She might be looking for 2000 metres."
A half-sister to Group III winner Under the Eiffel and stakes-winner Tower of Lonhro, The Pinnacle (images Steve Hart) is the third stakes-winner from stakes-placed Danehill (USA) mare Spire, who was a winner up to 2400 metres.
The Pinnacle is the second new stakes-winner for So You Think in less than 24 hours with his three year-old filly Think Bleue winning the Group IIII MVRC Alexandra Stakes at Moonee Valley last night.
The Pinnacle is the eighth stakes-winner for So You Think, who has 14 entries for Inglis Easter.
