A tragic fall on the home straight involving reigning Melbourne Cup winner Half Yours has marred the Caulfield Cup, with another horse euthanised on the track.

Chris Waller-trained mare Ohope Wins was put down on-course on Saturday as a result of an injury sustained when brought down by the fallen Half Yours.

Half Yours, who won a historic Melbourne and Caulfield cups double last year, escaped with only “superficial” lacerations, while jockeys Mark Zahra and Jye McNeil avoided serious injuries.

Racing Victoria confirmed both riders were taken to hospital for further observation, with stewards to conduct an inquiry into the racing incident.

The official crowd attendance of 30,051 was the largest in a decade for Caulfield Cup day in Melbourne.

The tragedy overshadowed Kingswood’s $6 million victory, with emotional trainer Gavin Bedggood shedding tears of joy.

Kingswood was the widest runner into the straight but avoided the falls and surged home.

The seven-year-old grey took the lead from Enfjaar with 100m left to run and won by half-a-length from Ciaron Maher-trained Saint George.

It was a first triumph as a trainer in a major for Bedggood.

Kingswood overcame a wide draw in barrier 17 to complete the upset, paying $26 on the TAB.

Half Yours co-trainer Tony McEvoy said the incident was “terrible to watch”.

“The horse, he’s got a couple of lacerations. He seems bright, he seems composed in himself,” McEvoy said in a statement posted on X.

“He’s got a laceration under his arm, he’s got a laceration on a hind leg. They look superficial. He’s just with the vets now but he came back to scale.”

Bedggood paid tribute to his family and staff.

“I”m just rapt for my team at home. They all turn up every day and they work really hard,” Bedggood said.

“I’m a hard taskmaster. I’m anal and like things done a particular way.

“They put up with me, and I don’t get the results that I’m getting without good people behind me.”Kingswood overcame a wide draw in barrier 17 to complete the upset, paying $26 on the TAB.

“We were pretty much posted three-wide all the way and everyone wanted to question the horse’s credentials at a mile and a half,” Bedggood said.

“We couldn’t condemn him on his (previous) run here. It was on a heavy nine and you had to put a line through it.

“It’s great to be vindicated.”
