Trainer Tiarnna Robertson has thrown down the gauntlet to her rivals in the Group 3 Northam Mazda Stakes (1100m) at Ascot on Saturday.

Robertson says if tactics are employed to take on Fabergino and disrupt her dominant front-running style of racing, they could come unstuck.

Noted speedster Mervyn is expected to take on Fabergino for the lead, but Robertson says her mare’s best asset will see her come out on top.

“We are not going to change our tactics and if they want to take her on so be it,” Robertson told Tabradio.

“She is a jump and run horse and always has been

“Leading into Melbourne everyone was telling me it’s not a leader’s race running down the straight, but that’s the way she runs and we are not going to change for another race or another horse.

“She will come out, jump and run and fingers crossed she can hold them off late.”

Fabergino has proved to be dynamic at short course sprinting with seven of her eight victories over 1000m and one at 1100m.

Her only real failure in 11 starts came in the Marjorie Charleson Classic last year when she was stretched out to a 1200m journey.

Despite 1000m being her pet distance, Robertson is confident Fabergino can perform as strongly over 1100m

“She has matured and strengthened a lot,” Robertson said.

“Obviously there are question marks over an extra 100m, but the way she has come through these last couple of races, she has been strong running through the line.

“That fills me with confidence to tackle a race like this with her.”

Robertson says Fabergino has come along in leaps and bound after a defining win in the Bob Hoysted (1000m) at Flemington in February.

It capped a Listed race trifecta for the daughter of Maschino after wins in the Crawford Stakes (1000m) and the Summer Scorcher (1000m) at Ascot.

“Even in the last couple of races I have noticed a change in her attitude,” Robertson said.

“She’s always been a headstrong sort of filly and she still is, but she has really matured into a race horse.

“She really knows what her job is, it’s taken her a while, but I’m really happy with the way she is leading into tomorrow.”

Fabergino has landed a plum draw in barrier one. Mervyn, with Jade McNaught aboard, will jump from gate four.

Peter Knuckey renews his association with Fabergino. A groin injury prevented him from being aboard her in Melbourne.

Fabergino is the $1.65 Tab favourite.
