The Grahame Begg-trained five-year-old will step out in the $150,000 open handicap over 1100 metres at Flemington.
It is the last heat before the $175,000 final, which is over 1200m, on the July 4 Finals Day card and Begg was reluctant to have De Bergerac go straight from the Listed Straight Six, in which he finished second on May 16, to the final.
"It was going to be six weeks between runs, so he's got to go around next week," he said.
"He loves the Flemington straight and this is his top-off run to go into the Santa Ana Lane two weeks later.
"He's already qualified for that because he ran second in the other race (last start)."
De Bergerac beat home all bar Losesomewinmore in the Straight Six, when he was a heavily-backed $2.90 favourite.
That was his sixth top-three finish from nine starts up the Flemington straight, where he has won twice.
