White Marlin remains unbeaten after taking out The Macca’s Run at Flemington.

The Gai Waterhouse and Adrian Bott stable hope to be back at Flemington in 12 months' time with White Marlin contesting the Melbourne Cup. 

White Marlin stretched his unbeaten streak to five with an emphatic win in The Macca's Run (2800m) on Tuesday. 

Tracking the speed throughout for Tim Clark, White Marlin, the $2.35 favourite, took over on straightening before racing to a soft 5-½ length win from Protection Money ($71) with Caboche ($8) a further 1-½ lengths away third. 

After two wins in the UK, White Marlin has continued that form in Australia winning at Rosehill in September before victory over 2000m on the middle day of the Caulfield Cup Carnival. 

Bott said White Marlin had taken it to another level with his victory on Tuesday. 

"He just keeps getting better," Bott said. 

"He was very impressive today. He's gone to a new level, up in class, up in trip, he was very dominant. 

"It's very pleasing to see and for the connections going forward." 

Bott said White Marlin may have one more start in Melbourne to finish up the Spring Carnival, but the stable was also mindful of not wanting to go too far, too early. 

"We did leave the option for one more run this campaign and we'll have a good look at the Sandown Cup with him stretching out over 3200 metres," Bott said. 

"I think it would be an option the way he ran it out today. 

"We're mindful of it being his first preparation over here and obviously the long-range plan is to be back here in 12 months' time. 

"We'll see how that 12-month program will look and we'll see if that run again fits in. 

"He's shown us enough potential today and we'll do what feels right for him."
