Trainer Bjorn Baker’s enthusiastic message to owner John Singleton came after Blue Door dominated the Group 3 $250,000 Heritage Stakes (1100m) at Rosehill Gardens on Saturday.

Blue Door displayed remarkable sustained speed to win impressively in time approaching the track record, earning a place in discussions for a coveted slot in the Group 1 $20 million The Everest (1200m) at Royal Randwick on October 17.

Although Singleton was absent for Blue Door’s victory, he can anticipate contact from slot-holders inquiring about his interest in The Everest.

It is understood that Newgate is taking a keen interest in Blue Door, as she is a progeny of their successful young stallion, Stay Inside.

Blue Door, in just her fourth start, secured her second win and added two placings, proving she possesses considerable natural speed as a filly.

“I tell you what no weight, weight-for-age, there is a race in three weeks – Singo you there?” Baker repeated.

“But that was exciting, she has always shown us a lot and we will see what happens.

“She would add a real dynamic to the race (Everest). She’s a very fast filly, she had to carry a bit more weight today, she has natural gate speed, she paraded great and is a filly on the rise.

“She set up a track record speed last time, you get them chasing and it could be an absolutely different story and with no weight, who knows?”

Blue Door has not raced beyond 1100m in her short career, and Baker offered a humorous response when asked about her suitability for 1200m.

“From 1100m to 1200m – Sir Edmund Hillary was getting to the final steps of The Everest and he got a bit tired but he found a way, it’s Kiwi trait. He was the first to climb Everest and he was a New Zealander,” Baker quipped.

The $1.85 favourite, Blue Door, was simply too quick and too strong for her rivals, winning by two-and-a-quarter lengths from Ciaron’s Star ($8), with Outspan ($41) a length further back in third.

Champion jockey Nash Rawiller, who has ridden many of Singleton’s top horses, most notably the outstanding mare More Joyous, will undoubtedly have glowing reports for the owner about the filly.

“Blue Door’s gifted, isn’t she! She’s just explosive,” Rawiller said.

“She has so much speed, it’s just harnessing it, I think. She’s too quick for her own good.

“It’s not very often you pull up and think, gee, this reminds me of a smaller version of More Joyous. I don’t know if it’s the colours of her, or just the long action but this filly is very exciting.”

Blue Door’s innate speed saw her take the lead early, and Rawiller was able to maintain a strong but controlled pace throughout the race.

“That’s her, though, she makes it look easy,” Rawiller said.

“Even though she makes it look easy, it’s a speed you can’t keep running, but she did a very good job today.

“She travelled well and with a couple of runs under her belt, she was really solid right to the line.”

Blue Door won the Group 3 Kindergarten Stakes on her sole start last season. Her current campaign began with successive seconds to Chilly Girl in the Listed The Rosebud and behind Guest House in the Group 3 San Domenico Stakes, before her commanding win in the Heritage Stakes.

“She was very smooth and lovely to see John Singleton’s colours winning,” Baker said.

“John isn’t here but his family is, his daughter is here, and this filly is pretty special to him.

“I’m very lucky to train a very good, very fast filly – and she is exceptionally fast.”

With her sights set on The Everest, Blue Door is attracting considerable attention from Australian betting sites.
