When David Hayes shifted his attention from Sha Tin to Flemington at about 1.31pm on Saturday, he was confident Circuit Jolly had his debut victory in the bag.

But while Lindsay Park’s banner horse, Mr Brightside, made no mistake for Hayes’ sons Ben, Will & JD on his way to landing an eighth Group One success in the Champions Mile, Circuit Jolly cost himself any chance of victory for the second time in as many starts by jumping a mark in the Sha Tin straight.

“It happened smack in the middle of Brightside’s race. I watched Circuit Jolly, he jumped well, he was travelling into the bend and he looked like he had the race in his control. Then I started watching Brightside and Circuit Jolly jumped that thing again,” said Hayes.

Leading comfortably on debut last month, the three-year-old son of Ten Sovereigns threw away victory when losing his momentum after jumping over a strip in the turf left at the 170m mark by the off-season installation of an irrigation pipe.

He repeated the dose on Saturday, again bounding while leading.

While the mark does appear to be fading, Hayes believes a change of scenery is required to reset his young charge, who clearly has some ability.

“He had the race in his keeping and he threw it away. He was worse this time,” said Hayes.

“He’s clearly sighting something on the track and jumping it. I think it’s a combination of [the mark and him remembering it from last time]. It just takes his momentum away. I looked at it the day before and I thought it looked fine, but the horse is spooked by it.

“The club have been kind enough to let me school him and walk him over it a number of times. That’s the first thing I want to do, but we’re probably going to target a Happy Valley race where there’s no crossings.

“I’ll probably give him a trial in blinkers just to help his focus a bit, then I’ll run him at the Valley and then I’ll do some schooling at Sha Tin before he runs there again.”

It’s not long since Hayes was having to do extra work with another enigmatic galloper, with Global Harmony banned from racing in Hong Kong earlier this year after twice refusing to jump on race day.

Now back in Australia with Ben, Will & JD, Global Harmony – who was rated 81 when departing Hong Kong – is edging closer to a return to competitive action.

“He’s got one more trial to go in Australia. He’s been passing his jump outs and ticking everything off,” said Hayes.

“He was ready to trial last Tuesday but he got a foot abscess and he couldn’t trial. We’ll be seeing him in the [Australian] autumn in the good races. He’ll race over summer there and if he finds his good Hong Kong form and forgets his antics, there’s lots of nice races in the autumn.”

As for Mr Brightside, Hayes confirmed there is still a chance he travels to Hong Kong despite connections putting a line through next month’s international races.

“They really thought about it, but the best part of the autumn for Brightside is the early part in February and March. They’re going to go for the three Group Ones in Melbourne that he always goes for and then they’re going to bring him for sure for the Champions Mile [at Sha Tin in April],” Hayes said.

Hayes also provided an update on young superstar Ka Ying Rising, who will be red-hot favourite in Sunday’s Group Two BOCHK Private Banking Jockey Club Sprint (1,200m).

“I thought his trial [at Conghua on Friday] was a little bit better than his trial before his last win. I thought it was quite nice and Karis [Teetan] was happy with him. He’s eating all his food and, touch wood, things are going along very smoothly,” said the trainer.
