A perfectly timed run by jockey Dwayne Dunn on Girl Gone Rockin’ saw the mare cause an upset win in the Group 2 $300,000 Momentum Energy Stakes (2000m) at Flemington today.

Just when the judge was going to call Queenstown the winner, Dunn was able to lift the Team Hawkes trained Girl Gone Rockin’ to get a nose decision over Queenstown who had been given every chance by Nash Rawiller.

Girl Gone Rockin’ was coming off a second over 1800m on the Kensington track at Randwick and was sent out a $17 chance but did enough on the line to beat Queenstown, the $4.40 second favourite with $12 chance Keep De Rose in third spot.

Rawiller crossed from a wide gate on Queenstown and settled in second spot while Dunn had Girl Gone Rockin’ out the back.

After easing the Gai Waterhouse trained mare over heels at the top of the straight, Rawiller had Queenstown in front everywhere but the post with Girl Gone Rockin’ making up five lengths over the final one hundred metres.

“She’s a lovely mare and deserved to win a Group race like this. She will make a lovely broodmare one day once they get her there,” Dunn said.

“She really pinned her ears and I just didn’t know late, was happy to get the bob.”

Wayne Hawkes representing Team Hawkes, agreed with Dunn saying that Girl Gone Rockin’ is destined for the breeding barn and today’s Group 2 win will enhance her broodmare value immensely.

“I thought about thirty yards to go we weren’t going to win and then right on the line she just bobbed the right way,” Hawkes said.

“It’s something special really to win a Group 2 race, a mares’ race, over the four weeks of the carnival, this mare’s value has gone up by about three fold in about a minute and a half.”

“She will probably go to the paddock now.”

The well supported favourite Lake Sententia ($3.80) was always well back and never threatened in the straight to finish just over three lengths form the winner in seventh spot.
