Mary Reveley has her horses in terrific form and a magnificent Musselburgh four-timer with Chaos Theory, Linea-G, Harfdecent and Riviere made it seven winners in a row for the stable since New Year's Eve.

The Saltburn trainer, who was taking her overall score for the season to 65, said: "I don't think we have ever had seven winners in a row before. I think we have had six on the Flat, we had four at Redcar one day and I think we had had two the previous day."

Reveley has five runners at Catterick today but she added with a smile: "I don't think we will be making it 12 in a row somehow!"

Chaos Theory, closely related to the mighty Desert Orchid and carrying the same colours, has plenty to live up to but at least he got his name on the score sheet for the first time in the Heart of Midlothian Maiden Hurdle.

Given a lovely ride by promising amateur Tony Ross, Chaos Theory was produced with a perfectly-timed run to lead at the final flight and go six lengths clear.
