Previously trained by Edward O'Rourke and Darren Weir, Ringerdingding showed his class last spring when taking out the Group II MRC Sandown Guineas and was entered for the Group I ATC Doncaster Handicap later in the program today, but missed a start when he was only listed as an emergency.
The easier race proved a soft target for Ringerdingding, who settled midfield for James McDonald and hit the line hard to win the 1600 metre feature by half a neck.
"Unfortunately he didn't get to the Doncaster," Chris Waller said.
"It's been the story of this preparation. In Melbourne he was very unlucky with barrier draws but things have just gone wrong and today they went right."
Winning rider James McDonald was well pleased with the son of Sebring and believes better wins are in store.
"He was able to race a little bit closer, which told late," McDonald said.
"He's a very good horse on his day and he overcame a few obstacles today which was good to see.
"No doubt we'll see him in some better races down the track."
A $170,000 Inglis Premier purchase from the Three Bridges Thoroughbreds draft for B2B Bloodstock, Ringerdingding was bred by Three Bridges in partnership as they purchased her dam Maybe I through Paul Willetts for $120,000 at the Inglis Broodmare Sale in 2015.
Ringerdingding is a half-brother to this season's stakes-placed two year-old Salome and is the second winner for Group III placed Red Ransom (USA) mare Maybe I, a grand-daughter of dual Group I winner Flitter.
Now with B2B Bloodstock, Maybe I produced a colt by Ringerdingding's sire Sebring last year and is now back in foal to him again.
