The recent Group 2 All Stars Sprint winner overcame a wide draw to work her way to the lead, before powering away to score by nearly five lengths in 22.40sec.
The win cemented Sveta Monelli’s splendid record on the Peel circuit, where she has seven wins and five seconds from 13 attempts.
Last year’s Mandurah track-star Buddy Be Cool proved he is no spent force, after he qualified for the race he won last year, claiming his heat in 22.57sec.
Wins have been rare for the Terry Erenshaw-trained black dog in recent times, but he displayed some of his old launching speed when he led all the way from box five.
The other heat was determined in an exciting three-way finish as Special Maestro overpowered Ritchie Rich and Uno Reltub on the line.
Special Maestro conceded the early advantage to the other two chasers, but came from behind in the home straight with a late surge that carried him to victory by a head in 22.47sec.
