Tiger Shark, the impressive three-year-old filly trained by Group 1 Stradbroke Handicap-winning trainer Natalie McCall, was being considered for a southern sprint tilt after putting the bite into her opposition when scoring at Doomben last month.

However, Tiger Shark, part-owned by Boost Juice tycoon Jeff Allis, is still doing a few things wrong so the spring blueprint has morphed into a summer mission.

Tiger Shark will have a hitout in Saturday’s Fillies And Mares Class 3 Plate (1200m) at Doomben and potentially one more run before then being put away to freshen for a crack at Queensland summer carnival riches.

“She is still doing a couple of little things wrong and you can’t be making any mistakes if you go to Sydney at this time of year,” McCall said.

“Damien (Thornton) said she wasn’t on the right leg in her last win and she was getting a little bit lost.

“Jeff (Allis) is nice and patient, we had a chat about it and we will take the softer option for now and hopefully we are rewarded a bit later.

“We just have to iron out a few little things with the filly, nothing terrible.

“So we thought we would just give her another couple of runs and then we will get her ready for the Mode Plate in the summer carnival.

“And then after that we will just give her a nice break and get her ready for next year’s winter carnival.

“We will get black-type with her somewhere along the line.”

Tiger Shark races out of her own age group for the first time on Saturday where she will face older fillies and mares.

But she will have a weight advantage over many of her rivals and has also drawn barrier one.

TAB now has her as a $3.20 chance after she went up $4.20 in opening markets.

“She is up against the older girls for the first time, but she is going really well,” McCall said.

“There’s nothing to stop her having a repeat of her last win.

“She is quite a big, gross filly and she will strip fitter on Saturday having trimmed up after her last run.

“She definitely hasn’t gone backwards.”

Bookies have pegged Rob Heathcote-trained four-year-old mare Outlawed, who has won her last two, as the $2.80 favourite.
