Conquistadores is a product of the Magic Millions March sales and will be ridden by apprentice Jace McMurray.
“He’s got 60kgs so we’re going with the claim for a bit of weight relief,” Peter said.
McMurray is apprenticed to trainer Adam Campton who won the Gold Coast trainers’ premiership last season.
Meanwhile, Peter is hopeful another apprentice, Rob Thorburn, can turn Sir Carter’s fortunes around in the Benchmark 65 Handicap.
Sir Carter has just two wins from 21 starts in his career.
