In a tough round of 32 heat, Grimus made an excellent start through the first section to be leading at the first turn.
After being pushed wide, Grimus lost speed through the major drag section, eventually crossing the line in third place.
“It’s pretty frustrating because all the bits are coming together, especially with the start that I’ve been working on, and now the speed is coming through qualifying,” Grimus said. “It’s building and building though through the season, so I’m excited.”
Head coach Shawn Fleming said he feels for Grimus.
“Anton had a great quali and we felt really good going into today, and he trained well this morning,” Fleming said.
“I feel for Anton because he is frustrated with missing great opportunities. All we can do is hope the weather holds and we get another chance tomorrow,” Fleming added.
Meanwhile, Fleming said Sami Kennedy-Sim is recovering well from her crash prior to the event getting underway, but will not take any part in this weekend’s events.
The second of the weekend’s two races will be held Sunday night (Australian time).
