Dinoblue led home a one-two-three for trainer Willie Mullins and owner JP McManus in the Paddy’s Rewards Club Chase at Leopardstown.

A field of five runners went to post for the Grade One contest, with Henry de Bromhead’s 6-4 favourite Captain Guinness the only outlier in an otherwise Closutton dominated line-up.

It was clear from a long way out that it was going to be a clean sweep for the champion trainer, with the market leader never able to get to grips with a strong pace and eventually pulled up by Rachael Blackmore in the back straight.

Gentleman De Mee was deployed in a front-running role, but he was a sitting duck at the top of the home straight, as stablemate Dinoblue moved into his slipstream under a motionless Mark Walsh.

Once given her head, the 9-4 shot soon pulled away and safely negotiated the final fence to score by seven and a half lengths.

Saint Roi was third, with the other Mullins runner Dysart Dynamo falling at the last.

“Gentleman De Mee set a great pace in front and jumped fantastic. I wondered at one stage would she (Dinoblue) be able to stay jumping with him but she held her jumping together,” said the trainer.

“When he took a blow, she kept galloping and she is improving all the time. I’m very happy with that.”

Dinoblue is the 11-4 favourite (from 7-2) with the sponsors for the Mrs Paddy Power Mares Chase at the Cheltenham Festival in March.

Dinoblue kicked off the new season as she finished the last with a determined victory in the Barberstown Castle Chase at Naas.

Runner-up when favourite for the Grand Annual at the Cheltenham Festival in March, the JP McManus-owned mare subsequently struck gold at Fairyhouse and Punchestown before enjoying a summer break.

The six-year-old was the 5-6 market leader for her reappearance in a Grade Three contest formerly known as the Poplar Square Chase and jumped and travelled with zest throughout in the hands of Mark Walsh.

Dinoblue’s stablemate Sir Gerhard was not done with when crashing out two fences from home, which left Fil Dor as her only serious threat.

The latter did his best to reel in the Willie Mullins-trained favourite on the run-in, but she was always doing enough to fend him off and passed the post with a length and three-quarters in hand.

“She jumped well and handled the ground well. It’s a nice start to the season and you couldn’t be happier with her,” said McManus’ racing manager, Frank Berry.

“I’m not sure what plans Willie has for her, but I’m sure there will be similar down the road.

“She was getting all the allowances there, which was a huge help. She will come on from the run and Mark was delighted with her.”
