Co-trainer Troy Corstens is hoping for a nice showing at Flemington on Finals Day this weekend for possible 2017 Ladbrokes Caulfield Guineas contender Whoomph who is out to break his maiden status.

The High Chaparral colt has had two career runs to date, the latest seeing him finish four lengths second behind boom two-year-old Royal Symphony as a $31 outsider in a juvenile’s handicap at the Flemington track over 1400m on June 24 after making up ground from the back.

Tony McEvoy’s undefeated Domesday colt Royal Symphony was elevated to pre-nomination favourite following that win for the Group 1 Ladbrokes Caulfield Guineas (1600m) this spring.

The Caulfield Guineas on October 14 could also be on the new season agenda of the Leon & Troy Corstens-trained Whoomph who faces his last start conqueror again this weekend in the $120,000 Listed Taj Rossi Series Final (1600m).

“We contemplated putting him out after his last start and getting him ready for the spring but he really bounced through that run,” Corstens told AAP.

The Flemington run last time out was a huge improvement on Whoomph’s unplaced seventh on debut at Pakenham on the Synthetic track over 1400m on June 8.

“We’ve always had a really good opinion of him and we were actually pretty devastated when he ran the way that he did at Pakenham,” Corstens said.

“It’s come to light since that the surface there is probably not up to every horse’s liking, so when he performed the way he did at Flemington it just confirmed what we thought of him the whole way along.

“He’s always been a very classy horse.”

Royal Symphony is the obvious youngster to beat in the mile black-type feature as he looks to retain his undefeated status and remain top of futures Ladbrokes Caulfield Guineas betting.

Whoomph meanwhile also gets the chance to enter early calculations and move up the all-in Caulfield Guineas odds when he steps-up to a mile for the first time on Saturday.

“We just thought the final is there so we’ve got to have a crack at it. And stepping up to the mile is going to really suit him,” Corstens said.

“We’re talking about the favourite for the Caulfield Guineas, so you’ve got to show him the respect he’s due,” Corstens added of Royal Symphony.

“If Royal Symphony is favourite for the Caulfield Guineas, we didn’t finish too far off him last start and I think the mile is going to suit him.”

The Taj Rossi Series Final attracted 16 nominations on Monday with other standout two-year-olds in the mix including Chris Waller’s Hinchinbrook filly Madame Moustache and the in-form Lindsay Park-trained Sepoy gelding Mulk.
