Giant filly Lunar Lights is on trial for Group One races in Adelaide and Sydney at the Sandown meeting on Wednesday.

The daughter of Bianconi and the unraced Encosta De Lago mare My Fair Lago goes second-up into the Betfair Hcp (1600m) and Troy Portelli, assistant trainer to his Sydney-based brother Gary Portelli, warned she was probably looking for longer.

"We're judging her as we go along race by race but if she gets into the prizemoney tomorrow we'll definitely head to Adelaide for the 2000-metre race (the Group One Australasian Oaks at Morphettville on March 21)," Portelli said.

"That give her time to come back after that trip and then head to Sydney (for the AJC Australian Oaks).

"She's a dour stayer. It's not as though we have to work her hard and wonder whether she will get over ground.

"She's a monster of a filly pushing 17 hands and she needs to be up on the pace, so it was good to see her hitting the line when she got back from a wide draw first-up."

Lunar Lights was having her first outing since finishing seventh to Samantha Miss in the VRC Oaks (2500m) at Flemington on November 6 when eighth to Red Flair over 1400m at Sandown on February 11.

"She's definitely filled out from the little break she did have from the spring and that was her first-ever race preparation. She hadn't done much before that," Portelli said.

The filly has raced seven times to date and broke through for her only win at her fourth start over 2010m in a Wangaratta maiden on October 10 last year.

She then ran a creditable fifth to The Tiger in the Listed Geelong Classic (2200m) on October 22 before the Oaks.

Jason Benbow, who won on the filly at Wangaratta and rode her at her last start, retains the mount on Wednesday.

Meanwhile, smart four-year-old Raffaello makes his first appearance for the Mark Kavanagh stable in the Torbek Hcp (1400m).

The Encosta De Lago entire was previously trained by his breeder and part-owner Jim Marconi who has given training away for health reasons.

Raffaello, a winner at Flemington and on both the Lakeside and Hillside tracks at Sandown, has had a seven-week break since running sixth to Hey Rosie over 1610m at Flemington on January 17.

He'll be ridden by Kerrin McEvoy who has three mounts on the seven-event program, the others being last-start Sandown winner Gatehouse in the Marvel Loch Hcp (1600m) and Sea Finniss Zip in the Poitrina Hcp (1500m).
