The powerhouse club added another premiership to its coffers on Sunday, defeating Cobden in South West Cricket's Twenty20 final to book a Sungold Cup berth.

Mortlake lifted the Sungold Cup - a tournament in which the best Twenty20 teams from across the south-west compete for a $15,000 purse - in 2018.

First-year captain Tyler Schafer was proud to add to the club's swag of premierships, but insisted the job was not yet complete.

"We've got to look at the big picture," he said.

"I took over captaining this year and I really wanted to focus on (Twenty20) cricket.

"To be honest, we haven't played our best cricket yet. That's still all to come. We have our eyes set on the Sungold Cup."

Schafer revealed tight bowling through the middle overs against Cobden helped secure the short-form trophy.

"The bowling through the middle with Jack Lehmann and Todd Robertson really tightened it up," he said.

The opening batsman backed his team to claim every available honour in South West Cricket, including the overall one-day premiership in March.

"I think we have the team to do it," Schafer said.

"We've shown that in Twenty20. It's more the transition from Twenty20 to 50-over cricket that will take a bit.

"That's especially true with the Sungold Cup in there on Australia Day and that.

"But that comes back to training and getting that right."

He revealed morale was strong among his tight-knit teammates.

"It can even just be getting together on a Tuesday and watching the Big Bash over a beer," Schafer said.
