Blacker is also a part-owner and soon-to-be-trainer of Quick Defence who took out a $53,000-to-the-winner race at Rosehill on Saturday.

He had bought the imported horse only 12 days earlier for $50,000 and now races him with eight Tasmanian partners.

After one more run in Sydney, where he is being trained by Chris Waller, Quick Defence will join Blacker’s Longford stable and be set for the weight-for-age races and major cups.

Blacker is confident that Blackberry Rose, who came from well back to win over 1350m, will also measure up to some of the better races over the summer carnival.

“We’ve been riding her on the pace and she hasn’t been finding the line as good as I thought she should,” the trainer said.

“I said to Craig (Newitt) to ride her a bit quieter, maybe a couple of pairs further back – I didn’t expect him to be five pairs further back.

“But the way she finished off suggests she should run 1600m-plus.”

Blacker said Blackberry Rose had been a bit unlucky not to break her maiden status sooner.

“If she had, she’d have been in the paddock a fortnight ago,” he said.

“Now that she’s won, she’ll have three or weeks out to freshen up and her main aim later in the season will be the Oaks at Mowbray.”

At least one tote and fixed-odds operator paid out on the wrong numbers after the last race.

Correct weight was declared on the placings of Mississippi Grind (No. 6), Really Sure (No. 8) and The Grey Crusader (No. 5).

However the correct numbers were 6, 5 and 8.

Ubet is believed to have paid out on the incorrect 6, 8, 5 result for about 10 minutes but other agencies, realising it was wrong, delayed payments.

Normally, once correct weight has been declared, the result cannot be altered for betting purposes.

But, on this occasion, betting agencies appear to have taken it upon themselves to correct the numbers.

Stewards will prepare a report for the relevant authorities.

Mississippi Grind won the race by 0.5 lengths from Grey Crusader with Really Sure 0.3 lengths further back in third place.

Trainer Michael Trinder was pleasantly surprising by Mississippi Grind’s performance after her training routine had been interrupted by an injury to trackwork rider Dianne Parish.

“She might be better than I originally thought,” the trainer said.
