Kalkee took a one goal lead with just minutes remaining in the game, but a late flourish of goals from returning player Brittany Keller was able to propel Harrow-Balmoral to victory.

Keller crossed to the Southern Roos from Nhill in the off-season and showed her value in round one, scoring the final five goals of the match as her side won 46-41.

Harrow-Balmoral coach Ebonie Salter said Keller was superb late in the match after a difficult start adjusting to her new teammates.

"Brittany was great, it wasn't really Sara Mccuish's day so Britt really carried that in the goal ring," Salter said.

"She started alright, her movement was really good but she just didn't quite have the confidence early.

"She really came through with the goods in the end."

Prior to round one, Salter said the key component for the A Grade side would be learning to gel as a team, with several new players introduced into the fold.

"It got better as the game went on," Salter said. "We really clicked with about five minutes left in the game and that is reflected on the scoreboard.

"Kalkee played really well. They were good right across the board, we just got there in the end."
