A veteran of 30 starts that have netted the six-year-old only three wins, Etymology was emphatic in victory over 2500m on December 22.
The gelding had a 2-1/2 year absence from the winner's circle until he won at Moruya in April and another gap until his win last time out.
Grimwade said the stable learned a fair bit about Etymology after his win at Flemington when he backed up for a third start in as many weeks.
“It took a couple of those back-up races to get him fit which surprised us but he's taking his racing really well,” Grimwade said.
“It's not James' style to pour the work into them at home and I think those couple of quick back-up races helped us learn a bit more about the horse.
“He's so consistent and hopefully he gets that confidence boost of getting his head in front and it will keep that momentum going.”
Grimwade said Etymology had come out of the Flemington win in great condition.
“James came down to have a look at him on Friday and was happy with him,” Grimwade said.
“His work on Saturday was faultless and we're really happy with him.
“He's a big staying kind of horse and the extra 300 metres isn't going to make too much difference and as long as he settles in his race that will take him a long way towards victory.”
