Tim Clark believes his Group One heroics at Randwick on Saturday could help propel him to a new level in his riding career.

The young jockey turned a wet and gloomy Saturday into one he'll never forget with Group One wins in the $2 million Doncaster on Sacred Choice and the $350,000 Galaxy on Atomic Force.

"I'm sure this will do my career the world of good," Clark said.

The 24-year-old is best known for his association with popular mare Hot Danish who has recently been retired from racing.

Clark has been enjoying an excellent season in Sydney where he is knocking on the door of a top five placing.

His Group One double took him to 40.5 wins in Sydney so far this term, trailing only Nash Rawiller (69), Corey Brown (59.5), Hugh Bowman (52), Glyn Schofield (49.5) and Kerrin McEvoy (43.5) in the premiership.

"I have had my best season to date, 40 winners is by far my biggest season yet," Clark said.

"I'm probably just on the cusp of being in that top echelon and this is certainly a great boost."

Originally from Young in south western NSW, Clark made an immediate impact when he came to Sydney and won the 2005-06 Sydney apprentices title.

His first Group One victory came in the 2008 Galaxy aboard the Tim Martin-trained Typhoon Zed.
