Gai Waterhouse is saving herself for an all-out assault on the final two rounds of the Sydney trainers' premiership battle after scratching her only runner from Saturday's Randwick meeting, Swift Alliance.

Waterhouse, who returned this week from a month-long European holiday, leads rival Peter Snowden by just 2-1/2 wins in the premiership race which concludes at Warwick Farm on Friday.

Snowden, who has seven runners at Randwick, resurrected his bid for the title with a winning double on the Kensington track on Wednesday.

Waterhouse's racing manager Robyn Hartney confirmed her boss would be watching the Randwick meeting from her loungeroom but would have a strong hand at both Canterbury on Wednesday and the metropolitan season finale two days later.

"We've got last-start winner Tinjirarni, Bondi Blonde and Exceed With Me on Wednesday and then at Warwick Farm we'll have last-start winners Boca Chita and Bermuda Bankroll going around as well as Moti, Refuse Me and Deedra," Hartney said.

Exciting colt Swift Alliance, who has won three of his four starts, was set to run in the General Nediym Handicap (1300m) but will be saved for a 1200-metre race at Rosehill on Saturday week.

Swift Alliance is being aimed at the Listed Show County Handicap (1200m) at Randwick on August 22.

"The owners are keen for us to keep him at the sprint journey and then step him up to black type," Hartney said.

The news of Swift Alliance's scratching was good for trainer Gary Portelli who has Sacred Orders in the General Nediym.

"Last campaign he was racing against horses like Causeyacan and they were too good for him on dry tracks but now the tracks are wet he's coming into his own and looks ready for this level," Portelli said.

Sacred Orders led all the way at Canterbury on July 15 to make it consecutive wins at the inner-city track over 1250 metres.

The track for his last start was a heavy eight, the same as Randwick track manager Dave Hodgson anticipates for Saturday.

The surface was rated a heavy (9) on Friday.

"He's a fast-running type and if you slow him down he doesn't sprint off the back of it," Portelli said.

"You have to let him run and Nathan (Berry) will do that."

Meanwhile, Waterhouse's stable jockey Blake Shinn has informed stewards he will not be able to make the weight for a couple of 53kg rides at Randwick.

Chris Munce replaces Shinn aboard Sequinella in the Our Maizcay Handicap and Kathy O'Hara takes over on Saturday Matinee in the Testa Rossa Handicap (2000m).
