Siggy Carr, with a little help from her Gee Gee friends, took the riding honours at Elwick on Sunday.
Carr landed a treble on Gee Gee Musicmaker, Gee Gee Lanett and Gee Gees Jet, with the latter just holding on to win the $20,000 Pink Cup.
On a good day for the girls, Georgie Catania chimed in with her second double at successive meetings, scoring on Northern Soul and Geegee Trendsetter.
As well as winning four of the eight races, the Gee Gee horses filled the first four placings in the main race, with Gee Gees Jet beating Geegees Doublejay, Gee Gee Red Prince and Geegees Soprano.
Scott Brunton and his partner Tegan Keys landed a training treble with Northern Soul, Going Purple and Catalyst Fire.
Underplay showed he could be a Devonport Cup contender with a dominant win in the Benchmark 82 Handicap.
After sitting behind the free-running Miss Hissy early, apprentice Chris Graham eventually took control on the David Miller-trained five-year-old and he strolled away to win by six lengths.
Up until 12 days ago, Underplay had never won beyond 1350m but he has now won his past two starts over 1620m and 2100m.
The Devonport Cup is over 1880m on his home track where he has won five races.
Miller has always been confident that the Written Tycoon gelding will get a middle distance, as his dam Darcenell won the Tasmanian Oaks.
Four-year-old mare Catalyst Fire is another winner that looks destined for bigger things.
