In-form trainer Vaughn Sigley says Black Heart Bart’s impost of 61kg holds no fears and he is adamant the son of Blackfriars can add the $120,000 Listed Bunbury Stakes (1400m) to his bulging racing resume on Sunday.

Black Heart Bart has emerged as one of WA racing’s hottest sprinters and after commencing his current campaign in November as a maiden he has put together a sequence of six wins including the past three in succession.

The boom four-year-olds tally includes major features in the Carbine Club of WA Stakes (1400m), the Summer Scorcher (1000m), the Cyril Flower Stakes (1200m) and last fortnight’s Pinjarra Classic (1300m) when he lumped 59kg.

“My gut feeling tells me he can handle an extra 2kg against a similar line up to what he met in the Pinjarra Classic,” said Sigley.

“I would have liked 60 or 60.5kg but you take what you’re given and I’m confident he can cope and be very hard to beat.

“They had their chance to run him down and make ground in the Pinjarra Classic but he has a brilliant turn-of-foot.

“He is bouncing around and although it will be his final run this campaign he has never looked or felt any better.”

Black Heart Bart will be joined by Dawn Approach to form a potent two-pronged attack for the Sigley stable.

The four-year-old has also enjoyed a top campaign with wins in the Mungrup Stud Sprint at Mount Barker and Miss Andretti Stakes (1200m) at Ascot.

The Statue Of Liberty stallion, who has yet to be tested at 1400m, was runner-up to Black Heart Bart in the Pinjarra Classic.

“There is a query at the distance but they said that also when he won over 1300m at Mount Barker recently,” said Sigley.

I know he has been up a while but he is also going well and I couldn’t be happier or ask much more from both of my horses.”

Antique Belle ran on strongly for third in the Pinjarra Classic and appears the biggest threat to Black Heart Bart, but Sigley says don’t rule out Danablue who finished eighth.

“He might have missed the placings but he had no luck in running,” said Sigley.

“I think he is the biggest danger in the race.”

Black Heart Bart, to be ridden by Glenn Smith, will have to defy modern-day racing history with Finito, who carried 57.5kg in 2003, the highest weight-carrying Bunbury Stakes winner in the past 20 years.
