Seymour trainer David Bourne is unsure about plans for lightly-raced filly Reverberates who created a big impression with her first metropolitan success at Sandown on Wednesday.

Having only her third race start, the daughter of 2003 AJC Australian Derby and Epsom Handicap winner Clangalang impressed her rider Damien Oliver with the way she came from last at the 400m to win the Indian Summer Hcp (1400m).

"She had the others covered a long way out. It was a nice, soft win and Butch (Bourne) was hoping to give her not too tough a ride if I could," Oliver said.

"She's a lovely, game filly and there is a lot of potential there. It's a matter of how far she can take it this time in."

Oliver said there was still plenty of improvement in Reverberates as she still had to fill out and strengthen.

"There is a lot of untapped ability there and it will take her a long way," he said.

Bourne said the filly would get over more ground as she relaxed well but added he had "no idea" where she would go from here.

The filly is out of the winning Kaapstad mare Startling Belle while her great-granddam is Blue Diamond Stakes winner Out Of Danger who is the dam of three-time Group One winner St. Jude.

Reverberates ($3 fav) was bred and is raced by OTI Racing, managed by Simon O'Donnell and Terry Henderson, along with eight others, and scored by three-quarters of a length from Little Antics with Lilian Evelyn third.

She completed a running double for Oliver who also won aboard the Robbie Griffiths-trained mare Nuclear Force who was first-up in the Marie Louise Hcp (1000m).

Meanwhile, the David Racovolis-trained filly Lisas Lago became the first of the progeny of Lago Delight to win a metropolitan race.

The three-year-old was well rated in front by Chris Symons in the Special Dane Hcp (1800m) and kicked clear down the long Hillside straight before holding on to score by three-quarters of a length from Mam'selle Rouge with Boom 'N' Zoom a short half-head away third.

Lago Delight, a son of champion sire Encosta De Lago, won his first two starts, over 1000m at Flemington and the Mitchell McKenzie Stakes at Moonee Valley.

After being beaten a half-head when runner-up to Scaredee Cat in the 2003 Group Two Ascot Vale Stakes (1200m) at Flemington he was unplaced in four Group One races before injury curtailed his career on the racetrack.

He has had eight individual winners on provincial tracks including Palzago who was third to Reean in the 2008 Listed Blue Diamond Prelude (1000m) at Caulfield.

Racovolis, who is down to just six horses in work at Mornington, paid $7,000 for Lisas Lago as a yearling in Melbourne and races her himself.
