Bosson gave the colt an inch-perfect ride on the horse he chose of the three contenders he could have ridden for Te Akau trainers Stephen Autridge and Jamie Richards in the $500,000 1600m race.
A finishing margin of less than two lengths split the trio, with Age Of Fire running second to Embellish and Te Akau Shark running fourth. Ever Loyal, trained by Tony Pike, was third.
It was Bosson’s early opinion of Embellish that ultimately paid group 1 dividends for him on Saturday.
"I’ve always liked him. He had raw ability as a 2yr-old and I knew as a 3yr-old he would be a top-class colt," he said.
After a quick getaway, Bosson placed Embellish perfectly in the trail behind leader Ever Loyal before easing off his heels approaching the home turn when he had the measure of the pacemaker.
Victory never looked in doubt for the $775,000 yearling sales purchase down the straight as his stablemates fought out the minor placings with Ever Loyal.
Embellish’s victory gave Bosson his seventh win in the 2000 Guineas. Six have been in Te Akau colours.
Though he came to a decision before the race on how to split the three Te Akau runners, co-trainer Jamie Richards could not.
"Everybody was asking me before the race which was the best one, but I couldn’t tip one and all three have gone very well," he said.
Richards and Autridge will now have the big task of placing their colt by Savabeel out of the O’Reilly mare, Bling, to further secure his future as a stallion.
"It’s a stallion-making race and this bloke has a top future," Richards said.
Te Akau’s group-1 celebrations turned to major concern just hours later when its star galloper, Gingernuts, was injured on the way to the barriers for the $A2 million ($NZ2.21million) Emirates Stakes at Flemington.
Rider Michael Dee told media that the horse was cantering to the start when he felt "something went amiss".
"I definitely felt it happen so straight away I pulled him up and got off as quickly as I could.
"It’s very unfortunate for the connections and not very nice to happen to the horse."
The jockey immediately dismounted and veterinarians were quickly on the scene.
The equine cult hero was late-scratched and then transported to the University of Melbourne Veterinary Clinic in Werribee.
Stewards later reported Gingernuts had been diagnosed with a fractured pastern in his near foreleg and would undergo surgery today.
Former Japanese galloper Tosen Stardom, trained by Darren Weir, won the Emirates from Happy Clappy and It’s Somewhat with a huge late finish after being denied clear running for most of the home straight.
Redzel reaffirmed his standing as the pin-up sprinter of Australian racing with victory in the $1 million Darley Classic. The Peter and Paul Snowden-trained gelding beat Australia’s sharpest horses in The Everest last month and backed it up on another big-stage success. Redzel led on the grandstand side for jockey Kerrin McEvoy as the field split into two divisions in the group 1 1200m straight race and the favourite prevailed by three-quarters of a length.
The 8yr-old Terravista, who Redzel narrowly beat in a listed sprint at Flemington during last year’s Melbourne Cup carnival, charged home with blinkers on for the first time to finish second. Stradbroke Handicap winner Impending was third.
Peter Snowden did not need any more convincing Redzel was the premier sprinter in the country, but he got it.
"I thought he did that in the Everest and the hype around was that he needed to prove himself again, and that’s what this horse keeps doing. He keeps stepping up and keeps proving all the doubters wrong."
Redzel has won his past six races stretching back to the Sydney autumn.
