Tim Clark believed honest sprinter Gold Edition's straight-track victory was overdue, but he had to wait even longer than expected after a nasty barrier incident caused a significant delay to the start of what was an eventful fifth race.

Clark ran into trouble last start on Gold Edition over the same course and distance after getting stuck in traffic, but made amends with a tidy ride on Me Tsui Yu-sak's consistent four-year-old.

"I got into a bad spot on him last start and I should've won," Clark said. "But today I made sure he had plenty of room and I was happy to see this horse win. He is a lovely horse that tries his best and deserved to win a race."

Veteran sprinter Vintage Hussler was eventually euthanised after an ugly accident that saw the nine-year-old crash his head first into the starting gates after being loaded, then become cast - the drama causing the Citibank Rewards Card Handicap to start more than 20 minutes past its scheduled post time.

Tom Queally had already been dislodged on his way to the start by his mount Delight Fortune, who was quickly caught and passed fit to run when Dane Patrol became fractious and burst through the starting barriers. Vintage Hussler then rammed into the closed gates and collapsed.

Vets quickly sedated the gelding and were able to eventually move the horse to the rear of the starting barriers, but not far enough that the rest of the field could be loaded. The Gary Ng Ting-kueng-trained runner was also still being treated and kept vets occupied, as all the while the 20,000-plus crowd grew restless.

Vintage Hussler was the likely leader and his withdrawal also caused a re-think of speed maps, but once the field was finally dispatched, Dane Patrol this time got an orthodox jump and gave Clark a horse to tag in the run.

"I did think I would be following Vintage Hussler in the run, so I got lucky when Dane Patrol came across from his gate in that it gave me something to follow," he said.

Clark's win was significant in that it was his first for Tsui after 17 previous efforts - the victory further entrenching him in the top five of the jockeys' championship with 28 wins.

Soon-to-depart Irish jockey Neil Callan will have to serve a suspension of the equivalent of three racedays after being found guilty of not riding the Ricky Yiu Poon-fai-trained four-year-old Atacx, who finished fifth, out to the line. Callan will begin a suspension after Wednesday night's Happy Valley meeting.
