An up-and-coming country sprinter could have his metropolitan return fast-tracked to capitalise on the absence of Sydney's strongest stables from a race for three-year-olds on Saturday.

Tamworth trainer Mark Mason took advantage of extended nominations to enter promising speedster Hot Hit in a benchmark sprint against his own age group at Rosehill.

"Originally I picked out a race at Canterbury next week but when the nominations were kept open for Saturday I decided to put him in," Mason said.

"No race is easy but there aren't any horses entered from the Waller or Waterhouse stables so that makes it attractive.

"There looks to be only one or two with genuine city form."

Hot Hit has won five of his nine starts, the latest when he looked beaten before kicking back to score from Kirinata and Fireball at Muswellbrook.

In his only Sydney start, Hot Hit ran just behind the placings at midweek level in January.

"Under the benchmark system he is getting hard to place in the country so there might be a few more trips to the city coming up," Mason said.

Robert Thompson has ridden Hot Hit in three wins but Mason is unsure if the champion bush jockey can make the trip to Sydney on Saturday.

Tromso, one of five Chris Waller-trained horses in the feature race, heads weights for the $100,000 Civic Stakes.

A winner of two of his past four starts, Tromso has 59kg, 1kg more than stablemate Coup Ay Tee.

Nine youngsters have been entered for the two-year-old race with Waller's promising Delectation shooting for a hat-trick after wins at Warwick Farm and Randwick.

Delectation has 59kg, 1.5kg more than talented filly Sheer Style.

Sheer Style failed in the Magic Millions Classic but she is already the winner of two races, including an easy return victory on the Kensington track at Randwick.

After having 24 acceptors for last week's Rosehill meeting, Waller will have numbers on his side again after nominating 18 horses in six races.
