Waller's quartet on Saturday took him to a Sydney record 189 metropolitan winners, 20 more than the previous standard he set two years earlier.
The eight-time premier trainer wasted no time on Wednesday, winning the first race of 2018/19, and the first Sydney race for the newly turned three-year-olds, with Charge who races in the colours of Qatar Bloodstock.
Ridden by James McDonald, Charge ($2.80 fav) beat stablemate Altair ($4) by 3-1/2 lengths in the 1100m-maiden.
“We purposely brought him back a bit early to try and give him a bit of confidence,” Waller said.
“I think the sky's the limit for a horse like this. I won't say how far he'll get because I certainly don't know.
“I'll be aiming high.”
Formerly trained in New Zealand by Kevin Myers, Follow Suit claimed his third Australlian win and third at Wariwck Farm in the 2200m handicap.
Carrying 60.5kg, Follow Suit ($4.60) beat the Waller-trained Cormac ($3.50 fav) by 1-1/2 lengths.
Both are in the field for a 2400m-race at Randwick on Saturday in which Waller has all but one of the 11 runners.
Sweet Scandal and Impasse completed the stable's winners.
Ready To Prophet was disappointing on debut at Canterbury on July 4 on a rain-affected track.
“A few things went wrong at Canterbury and I don't think she liked the ground,” jockey Tim Clark said.
“She was very impressive today and it was nice to see her produce that.
“Obviously it's not going to get any easier at this time of the year and I'm not sure how deep they plan to go into the spring but there's options for a filly like this.”
