Stylish Doomben winner Stroak is another example of a successful rebuilding strategy by trainer Bryan Guy.

Stroak gave Guy his second two-year-old winner from only three juvenile races this season when she won Saturday's Teldaco Handicap (1010m) at Doomben, following the victory of stablemate Grapevine at the same track a week earlier.

"A lot of our older bread-and-butter type horses have all retired or gone as far as they can so I bought a lot of two-year-olds this year," Guy said.

"We've got 25 two-year-olds and a few of them will be coming through in the next few weeks and I think they'll measure up as well."

Guy paid $27,000 for Stroak and will spell the daughter of Real Saga before aiming her at the Magic Millions Classic (1200m) at the Gold Coast in January.

"She's out of a Redoute's Choice mare and even though she sat outside the leader today I think she'll be even better when we can ride her quiet and let her get home," he said.

"In her trackwork she's showing us the further we go with her in distance the better she'll be."

Stroak, the $2.90 favourite, surprised jockey Michael Cahill with the speed she showed out of the barriers and surged clear in the final 200m to win by 1-3/4 lengths.

"On what she did in her barrier trial I expected to be near the tail of the field and running on but she began brilliantly and put herself outside the leader without using up too much energy," Cahill said.

"It was a pretty soft win and I only rode her out hands and heels.

"With two-year-olds a lot of times they don't find much extra when you hit them but I'm sure that filly would've today if I had to put her under more pressure."

Cahill said Stroak was inclined to stargaze on the home turn but believes she has plenty of scope for improvement.
