Tony Pike's decision to let Haussmann take his place in the listed Great Northern Foal Stakes at Ellerslie proved a wise move.
The Cambridge trainer had major concerns about the heavy going yesterday, but rolled the dice with the youngster in the Graeme Thomson Jeweller-sponsored feature and the son of Pour Moi came up trumps.
"He'd only ever trialled and raced on good or dead ground, but it is a stakes race and it was always going to be his last run for the season," Pike said.
Ridden by Vinnie Colgan, Haussmann was forced to cover extra ground near the back of the field before he circled runners across the top.
The 2-year-old stuck grimly to his task in the straight and, despite not enjoying the footing, he proved superior in the run to the line.
