Grant Williams believes a weight swing will present Dreamaway with her best opportunity of upsetting Luckgray when they meet in tomorrow's $125,000 Group 3 Belmont Sprint (1400m).
Dreamaway, to carry 54kg, will enjoy a 7kg weight advantage over Luckgray after running fifth to the Gino Poletti-trained gelding in last fortnight's Roma Cup (1200m).
The Roma Cup was Dreamaway's long awaited return after she failed to perform in Melbourne when placed 8th, 11th and 12th respectively during last year's spring carnival.
The daughter of champion sire More Than Ready was sent east after dominating Perth racing as a three-year-old with victories in the Champion Fillies Stakes (1600m), Ascot Thousand Guineas (1800m), Natasha Stakes (2200m), WA Oaks (2400m) and WA Derby (2400m).
"I was happy with her run in the Roma Cup and if not for getting held up she would have finished closer," Williams said.
"Luckygray is obviously the testing material and beat us fairly easy the other day.
"But Dreamaway has 7kg's on him and if she was ever going to get close it will be on Saturday."
Dreamaway is one of three entrants for the Williams stable with Battle Emblem and Avante worthy of claims.
Avante has drawn barrier four for apprentice rider Jordan Mallyon and ran a narrow second to Zester in the Bolton Sprint (1200m) on May 12.
Battle Emblem, to be ridden by Kyra Yuill, jumps from gate 11 and will be out to atone after trailing the field in the York Stakes (1600m) earlier in April.
"The barrier will make it awkward but if he gets any luck he will beating a few home," said Williams.
"He did okay in this race last year and generally races well fresh.
"The sting out of the ground may help Avante and hopefully from the draw she can have one final crack at them."
Luckgray will have to top the performances of Marasco (2008) and Grand Nirvana (2011) who won the Belmont Sprint with 60kg.
"I'm totally happy with the horse and the improvement he has shown since his last win," said Poletti.
