Ellsberg tuned up for the upcoming Brisbane Winter Carnival by taking on Royal Ascot bound sprinter Nature Strip in a jump-out on Tuesday.
The Gerald Ryan and Sterling Alexiou-trained son of Spill The Beans is now due to head for the Group 1 Kingsford-Smith Cup on Saturday, for which he is a 10/1 chance.
Ryan was pleased with the work that he saw and is happy to send the four-year-old to this weekend's 1300-metre contest at Eagle Farm. The Stradbroke Handicap is also on the agenda just a fortnight later.
"He had a jump out (Tuesday) morning and ran second to Nature Strip," Ryan said.
"He went well. Nash (Rawiller) came out and rode him and he was quite happy with him. He runs in the Kingsford-Smith on Saturday."
Ellsberg won the Group 3 Liverpool City Cup and finished third behind Cascadian and Tofane in the Group 1 All Aged Stakesin a productive autumn carnival campaign.
Heavy rainfall has seen some of the feature races set to be run at Doomben on Wednesday now transferred over to a bumper 10-race card at Eagle Farm on Saturday.
