Miss Zig Zag had not raced or been tested over 520m in 10 weeks but was still able to run her rivals off their legs at Wentworth Park on Saturday night.
The Syd Swain-trained speedster reeled off a dazzling first split of 5.38 and a second section of 13.68 before winning by over five lengths in a personal best 29.58 for the 520m.
"Miss Zig Zag hurt her hock when she led before weakening out of a place at Wentworth Park on September 28 and tonight she was having her first start since resuming,'' Swain said.
"I was confident I had given her enough work to see out the 520m but she was still very fresh.
"Hopefully tonight's race will top Miss Zig Zag off perfectly for the heats of the group one Ladbrokes Paul Wheeler Simply The Best at Wentworth Park next Saturday night.
"I certainly think she can improve on tonight's run home time of 11.83.''
Ayden's Warrior's blistering 29.31 performance to win over 520m at Wentworth Park on Saturday night almost certainly has put the dog's transition to long-distance racing on hold.
Trained by Jodie Lord for breeder Craig Sheridan, Ayden's Warrior began smartly and wasn't headed in the 520m event, not only producing a personal best 520m time but running home in an extraordinary 11.49.
Andy Lord, the trainer's husband, has long declared that staying would eventually be the preferred option for Ayden's Warrior and his litter brothers and kennelmates King Tide, Lucky Blue Book and Law Book.
But Ayden's Warrior does not turn three until May and looks to have plenty of 520m wins in him before he is switched to long-distance racing.
Saturday's win took Ayden's Warrior's tally over 520m at Wentworth Park to seven wins and four placings from 13 appearances, justifying Andy Lord's recent declaration that "this fellow is a real race dog!''
My Monroe and My Pharaoh, who each led throughout on Saturday night at Wentworth Park, are owned and trained by Sue Smith, and are the great, great grand-daughter and great, great grandson of the greyhound her partner John Miles regards as one of his best ever.
My Pharaoh and My Monroe's dam is My Sapphire, who won 14 of 31 races, is a daughter of Blue Thunda, who won an remarkable 18 of 23 starts.
Whinging Wrench, Blue Thunda's dam, won 20 of 37 races for John Miles and was a daughter of Tommie's Placard, perhaps his all-time favourite.
"Tommie's Placard won 17 races over distances from 280m to 520m and at one stage she won four in a row at Wentworth Park,'' Miles said.
"She finished second to Lilli Pilli Power in the 2005 Tweed Heads Galaxy and that was a race I always wanted to win, but I managed to do so in 2012 with Chasing Glory.''
My Monroe showed brilliant early speed on Saturday, a trait typical of her breed, posting early splits of 5.46 and 13.81 before covering the 520m in a personal best 29.92.
Ninety minutes later My Pharaoh displayed similar brilliance from the boxes to carve out early splits of 5.48 and 13.79 before clocking 29.62 for the 520m, also a personal best Wentworth Park time.
My Pharaoh had taken out the $25,000 to the winner Young Star Classic at Wentworth Park on October 18.
Sue Smith said: "My Pharaoh has always been a bit quicker than My Monroe but she has been hampered by wide draws.
"Although she won from box eight on Saturday night My Monroe really doesn't like outside boxes, she is better from the rails.''
Saturday's top grade event was taken out by the Minnie Finn-trained group one National Futurity winner Gets Late Early, whose success took her earnings to nearly $215,000.
Gets Late Early began fast from box six and lifted her tally wearing the green rug to four wins from eight appearances when she led throughout in 29.54.
Her first split was a flying 5.36, a mere .06sec wide of her quickest figures recorded 11 months ago.
There have been fewer easier first-up Wentworth Park wins than the 15 lengths romp by the Tony Mason-trained Honk Honk, who scored her third win in five starts with an all-the-way 29.66 performance.
"While she had not raced at Wentworth Park I had given Honk Honk a post-to-post slip and a box-to-box trial there so she knew her way around the track,'' Mason said.
