Royal Tithe booked herself a place in the winter stakes races with a Doomben win, but trainer John Zielke was equally pleased with stablemate and runner-up Stryking Stunnah.

The favourite Royal Tithe ($2.25) gave Zielke his fifth two-year-old win of the season when she beat Stryking Stunnah ($8.50) by 1-3/4 lengths with two lengths to Royal Hussy ($12) in the Mary Valley Handicap.

Zielke said Royal Tithe would now go for a spell before being brought back for the winter carnival.

"She will have a couple of starts in the Listed lead-up races and then tackle the (Group Two) Queensland Sires' and the (Group One) JJ Atkins Stakes," he said.

"Royal Tithe is a good tough horse who has picked up a cheque at each of her six starts. She will be off to Melbourne after the winter and I think you will see a very good filly in the spring."

He is also looking to the future for Stryking Stunnah who led into the straight.

"At one stage I thought she was going to beat Royal Tithe," Zielke said.

"I think she will have a real future over more ground."
