The Hawks No.3 crossed four times in two games as both her under 18s league tag and opens league tag side won through to this Sunday's grand finals in Bathurst, and she loved every minute of it.

"I'm so keen oh my God," Baker said post-game of the prospect of back-to-back grand finals, grinning from ear to ear.

"We're very happy but in the back of my head know we need to get to training and work hard during the week."

The young side will come up against CYMS in an all-Orange derby in the under 18s league tag, while Hawks take on the daunting St Pat's in the opens decider.

A remarkable eight of the 18 Hawks senior sides will be backing up grand finals, with Jes Pearson, Millie Lenahan, Courtney Morgan, Savannah Moore, Emily Irwin and Caitlin and Rebecca Prestwidge joining Baker in playing the both games.

Baker and experienced head Jacky Lyden have both hailed the mix of young and old as superb in the past few weeks.

Lyden said the youngsters had invigorated the more experienced players, while on the eve of finals Baker said the mixed squads felt like "a family" and give the thumbs up to the experience and advice from the likes of Lyden, Bec Ford, Cheynoah Merchant, Em McDonald and more.

The flow-on effect of that mentoring was on full display on Sunday as the under 18s dismantled the Mudgee Dragons 46-4, including three scores in the opening four minutes as Baker (three tries) Jes Pearson (two) and Courtney Morgan-Jones (two) all cashed in.

"We knew we had a lot of things to work on in 18s, completing our sets in particular," Baker said.

Baker added she loved the all-out attack giving her chance to score, saying it was a "pretty mad" to have four tries to her name across the day.

"I love the feeling of getting up from a try and the whole team is getting around you. It's just the best feeling to get your family around you," she said.

Morgan-Jones the onslaught "just happened" with no emphasis on starting that hard against the Dragons.

"We worked as a team and gelled really well and wanted to work through to the grand final ... our hard work all year paid off," she said.

However, Morgan-Jones said the defensive effort was just as important, with a focus on not letting the Dragons score after half-time coming to fruition.
