Toolleen trainer David Jensen heads into Friday night’s Group 2 Geelong Gold Cup heats with three litter siblings and a big chance to compete in the $67,000 feature the following week.

Eight Geelong Cup heats means there is no margin for error, only the winners will make it through to the 2018 Group 2 Geelong Gold Cup.

Big Flash Marjen, Big Sam Marjen and Sideshow Marjen make up three of the Barcia Bale and Big Bang Marjen litter who was bred by Matthew Murphy.

Big Flash Marjen is Jensen’s first of three contenders and hasn’t he drawn a tough race. A notable wide runner, Big Flash Marjen has drawn box three in the opening Geelong Cup heat.

“If he gets a clear run he is in with a chance, but you can’t forget how good some of the dogs are that he is up against,” trainer David Jensen said.

Group 2 Cranbourne Cup winner Mossimo Bale will jump from box one and Harry Manolitsis’ Italian Plastic who is aiming for three wins on the trot is drawn ideally in box eight.

“Like his brother Big Sam Marjen, Big Flash Marjen loves a wide draw so box three isn’t ideal for him in his Geelong Cup heat.”

Big Flash Marjen is a winner of seven races from 20 starts and has banked more than $14,000 in prize money. He has run second in two restricted win VIC Bred races, one at Horsham and the other at Shepparton being beaten a combined 5.79 lengths.

Sideshow Marjen is the lightest raced out of the three, having had just seven starts but has recorded six wins and a second placing.

“Sideshow Marjen has had a couple of niggling injuries which meant I had to scratch him from his last two starts at Healesville and Shepparton, but has come good after some time off,” Jensen said.

“Sideshow Marjen has guts and tenacity which is what sets him apart from Big Flash Marjen and Big Sam Marjen – he also boxes a lot better.”

Jensen believes that patience is the key to success with greyhounds.

“You need to take your time with young greyhounds, make sure that they are confident in their environments which will mean they race better, and I believe they don’t develop as many injuries.”

Sideshow Marjen finds himself up against one of Victoria’s best sprinters, Orson Allen (box five) as well as the consistent local Wise Piquet (box eight).

Big Sam Marjen is Jensen’s final contender in the Geelong Cup heats on Friday night and he is ideally drawn in box eight, so much so, the Watchdog have tipped him to come out on top.

“He loves a wide box and he has a big motor,” Jensen said.

In August, Big Sam Marjen stopped the clock at 25.58 second at Warragul over the 460 metre distance from box seven.

“When I looked up at the clock I couldn’t believe it, I was so surprised and very proud.”

Big Sam Marjen finds himself up against talented field on Friday night which includes Michelle Mallia-Magri’s Zoom Out who is knocking on the door of a Country Cup win.
