The Melbourne Cup dream is alive for the next generation of the Cummings family with Ruling Dynasty taking a major step with his win in the City Tattersalls Club Cup at Randwick.

The four-year-old's Listed win over 2400m on Saturday takes him past the first ballot clause for the Melbourne Cup.

All going well, he could follow the path taken by Maluckyday five years ago when that horse followed his City Tatts win with victory in the Lexus and second to Americain in the Melbourne cup.

But like his late grandfather and training partner Bart, James Cummings will not be hurried into a decision.

"It's not an easy decision," Cummings said.

"There is no doubt he will be more seasoned next preparation.

"And we need to see how he comes through today. But he is a very special horse and he's an Australian-bred horse who could take on the internationals."

Bart Cummings holds the Melbourne Cup record of 12 and his most recent runner, veteran Precedence, is also trying to make the field again.

Sent out at $4.80, Ruling Dynasty travelled kindly for Tim Clark just behind the pace after the riderless Sasenkile circled the field and led without disturbing the other runners.

Sasenkile came out of the barriers awkwardly before tossing Serg Lisnyy who was unhurt.

Prince Cheri took the lead in the straight but was under siege from Junoob ($7) and Ruling Dynasty.

Eventually Ruling Dynasty gained the ascendancy by a short neck over Junoob with Prince Cheri another three-quarters of a length third.

Ruling Dynasty is raced by Cummings's grandfather-in-law, Eduardo Cojuangco's Gooree Stud and a family discussion will take place before a decision on a Lexus Stakes run.

The Peter and Paul Snowden training partnership brought up a stakes double on the program with Nayeli ($8.50) getting the nod over Peace Force ($7) in the Group Three Nivison (1200m).

Earlier Dothraki beat stablemate That's A Good Idea in the City Tattersalls Club Lightning (1100m).

Winning jockey Josh Parr admitted he had no idea whether or not he had won and Tye Angland on Peace Force was none the wiser.

"We asked each other as we went by the post," Parr said.

"We both had no idea.

"To Nayeli's credit she stuck her nose out and got the job done."
