Bachasson's victory in the Boomerang Animal Bedding And Boomerang Horse And Country Store Chase was the highlight of a double for Willie Mullins and Paul Townend at Thurles.
The 8-11 favourite tracked Val De Ferbet in the early stages of the Listed contest and travelled powerfully throughout, before pulling clear on the back straight and leaving the pacesetter 24 lengths behind at the line, with Townend barely having to move a muscle.
The double was completed when 11-10 favourite Ainsi Va La Vie was equally impressive in winning the Sportsmens Mares Maiden Hurdle.
Townend was happy to track the early pacesetters on the grey, who picked up in taking fashion when asked turning for home and powered clear to win by 13 lengths from Martello Park.
Billys Hope gave Jessica Harrington a winner when landing the Go Racing At Thurles Mares Beginners Chase.
