Enabler had seven starts for Tregea, winning three times, and is expected to take a lot of benefit from his first-up run for King.
“He had every chance last start but he just raced a bit too keenly that’s why we’re dropping him back in distance,” King said.
“I think he’s improved since his first run for me and he’ll be competitive.
“He’s just got to learn to relax more but that will come with maturity.”
Tregea took Enabler to Rockhampton in June in search of a big track where he easily won a Class 3 before he had his last run for him finishing fourth at Eagle Farm in mid-July.
King is highly regarded for his horsemanship and is a son of Norma King, who trains at Miles.
He rode 105 winners in nine years as a jockey and trained his first winner when Incentivise’s half-brother Argyle Lane won at the Sunshine Coast on Sunday.
The highly promising Argyle Lane maintained his unbeaten record from two starts when he strolled home to win a Class 1 by more than two lengths.
Argyle Lane is the last foal of Tregea’s Windemere Stud mare Miss Argyle who tragically died last year while foaling.
