Wangaratta trainer Daniel McCarthy completed a 24-hour rollercoaster of emotions with Ashdam's disqualification in the Corowa Cup on Sunday followed by the victory of full-brother Ashlor at Moonee Valley on Monday.

Ashdam was sent out the short-priced $1.75 favourite in the Corowa Cup and was first across the line before controversy erupted with apprentice jockey Chelsea MacFarlane weighing in 600 grams light which led to the five-year-old being disqualified.

Runner-up Girls Own was awarded the race and events surrounding the jockey weighing in light are the subject of an adjourned inquiry.

McCarthy said he and owners, the Strain family, were still scratching their heads how they lost the race.

"The poor old owners had a fair kick in the guts yesterday along with their trainer and the rest of the team," he said.

"I saw the weight was right with my own eyes, she stood off the scale, gave me the saddle.

"There should have been no reason why it happened. Everything appeared fine.

"Unfortunately it has happened and no one can put a finger on why.

"It will be one of those things we will be talking about for a long time."

Ashdam finished runner-up to Darren Weir-trained star Burning Front at the Wangaratta Cup meeting seven days earlier.

Burning Front won again on Monday in the CS Hayes Memorial Cup on the Adelaide Cup card.

Ashdam's connections were originally planning a shot at back-to-back Albury Mile wins this Sunday.

But the Corowa Cup was targeted instead with a crack at the Albury Cup in mind five days later.

"We couldn't run in the Albury Cup if he ran in the Albury Mile," McCarthy said.

"We thought if he won the Corowa Cup with that sort of weight (60kg) he deserved a go.

"If it's going to be ridiculously strong we will stay home, but if it's winnable we will have a crack."

McCarthy has eight horses on his books including Kabrocco, who won on Wangaratta Cup day.

His small team has had eight wins from 30 starts this season with Ashlor the latest success story.

"It's nice to atone for yesterday, but it would have also been great to back-up yesterday," he said.

"He is still very green as you saw on the corner and doesn't really know what he is doing.

"To be left in front like that and still win is just an enormous effort.

"If we can teach him to relax he will be a much better horse."

Ashlor has now had three wins from four starts and his Moonee Valley victory followed two recent trials on his home track and Wagga after a four-month stint in the paddock.
