For the fourth match running, the Roos were sunk by the Swans at Goulburn's Goodhew Park, who retained the coveted Burnass Cup, 11.11.77 to 5.6.36.

The Roos came into the match at a disadvantage, as a host of injuries and unavailabilities meant that they arrived in Goulburn with a team of 17.

To accommodate the smaller numbers, Goulburn agreed to play a 16-a-side game, which saw both sides forced to adjust their styles of play.

"We were down on numbers today," Roos coach Adam Curtois said.

"They're a quality team, they've beaten us in all three games this year. I think we were a bit better than the scoreboard showed today, but at the same time, we could've definitely done a few things better."

The first half of the game was an arm wrestle for control, as both sides fought it out to gain possession and configure their styles of play to a much more open field.

Unfortunately, the Swans' run-and-carry style was better suited to a game with fewer players, and the Roos' naturally congestive style of play was less effective.

While he was disappointed, Curtois said that his side is only young and will take away valuable lessons from tough losses.

"Skills are definitely one thing that could've been better today," he said.

"We've still got a lot of guys who are in their first year of football. They're not complete footballers yet, but they're all keen to stick around for a number of years, so I see it getting better.

"But until then, we've got a bit of work to do to compete with those top sides."

As is always the case in matches between Yass and Goulburn, it was highly competitive with players going hard at the ball and making sure to leave some bruises behind.

However, the end of the match saw tempers flare after some careless knocks, but Curtois was confident that all issues had been left on the field.

"Every time we play Goulburn, it's always a physical game and there's always heated moments throughout the game," he said.

The Roos will look to bounce back from their loss against Goulburn with the third and final Yass Valley home derby against the Murrumbateman Eagles, which will take place this weekend.

It will take place as part of the Roos' annual Pink Day, and will be one of four matches to take place at Joe O'Connor Park.

The day will raise money for the Yass Valley Can Assist branch. Saturday, June 27, will kick off with a women's match between the Cootamundra Blues and Queanbeyan Tigers at 9am.

Three more matches will follow, with the Roos and Eagles last at 3pm.
