"He rode him [Greencast] beautifully," he said.
"I told him to jump out from the wide draw, aim for the corner and they will soon work out what they all going to do.
"He ended up with a lovely trail and they went hard up front.
"He rode him really well so good on him."
Gibbs was pleased with the performance of both of his runners who will now be aimed at the ITM Whangarei Gold Cup (2100m) on July 14.
"Both of the horses are aiming for the Whangarei Cup which has been our target," he said.
"Jake the Muss will hopefully then carry on through to the New Zealand Cup later in the year. Greencast might do that too but our earliest target has to be our local one.
"I was so pleased with Jake The Muss as he is definitely a New Zealand Cup horse."
Gibbs had earlier won a maiden 1400m contest with Tavezbac and went on to collect further victories with Vinevale, Not Usual Heart and Kyrie Eleison to round out the day.
