Zebrinz ended his last campaign with three straight wins and co-trainer Troy Corstens is now looking forward to seeing what the gelding can produce this time in.

Five-year-old Zebrinz is nominated for three races, including the Group Three Aurie's Star Handicap, at Flemington on Saturday and Corstens said a decision would be made which race he resumes in just before acceptances on Wednesday.

"He'll probably run in the 1000 metre race or the Aurie's Star," Corstens said.

"We're just waiting to see how he gallops tomorrow morning to decide.

"He's going in off one trial so we'll make a decision after he gallops tomorrow on whether he runs over 1000 metres or the 1200."

Zebrinz has 59kg in the benchmark-84 over 1000m while in the Aurie's Star (1200m) he has 54kg and is among 20 nominations headed by dual Group One winner Trust In A Gust.

Zebrinz won a benchmark race at Ballarat and then a Sandown midweek race in March before ending his campaign with a convincing win in the Vobis Gold Mile (1600m) at Caulfield in April.

"He's just a horse that every time we raised the bar with him, he just kept stepping up," Corstens said of his autumn campaign.

"Who knows where he'll get to this time in.

"It's tough to think about where he'll get to, but I think he's quite a nice horse."

Corstens said Zebrinz has improvement to come from his first-up start but said he was going well and trialled nicely in a jumpout at Flemington last Friday.

Trainer Patrick Payne told Melbourne Radio station RSN that Ihtsahymn will resume in the 1400m handicap at Flemington on Saturday rather than the Aurie's Star.

Ihtsahymn, the 2013 Group One Kingston Town Classic winner in Western Australia as a three-year-old, will be having his first start for the Payne stable having not raced since being unplaced in the Perth Cup on January 1.
