Princess Zesta recorded a personal best time for the 520m at the track when she lifted late to beat Federal Morgan for her 10^th win in 59 starts.

A $9 chance, the black bitch was second on the rails heading to the first turn after jumping from box two. She spotted Federal Morgan as much as four lengths on the back straight but railed the final turn and ran down her rival to win by a head in 29.95 seconds.

Princess Zesta had not won in her previous four starts at the track, which had all been at 720m. However, she had won there over 520m in April last year.

"She is probably capable of clocking around 42.50 over the 720m trip and could win a long-distance race at Wenty, but in each of her staying races she has run into a dog running very quick time,'' Grimwood told thedogs.com.au.

"Princess Zesta was well drawn near the rails in box two tonight and only needed to get a clear go early to be hard to hold off and that's how it worked out.''

It was part of a Hunter-trained double.

Salt Ash trainer Stephen Davies' Knocker Elly burst to the lead from box seven in a Golden Easter Egge Prelude (520m) and she bolted to a six-length win. It was her second in a row at the track and third in her past six starts, all at Wentworth Park.

At The Gardens on Saturday night, Cessnock trainer Wendy Brown had a winning double with Harmat and Flashy Manner.
