Western Force skipper Matt Hodgson hailed his side's superb start in Saturday's 30-20 win over the Reds in Perth.
Departing wing Nick Cummins scored a try and had a hand in another - scored by Ben McCalman - as the hosts raced into a 17-3 lead inside the first 20 minutes.
The Reds fought back to tie the match at 20-20 after 68 minutes, but the Force responded with a late try to hooker Nathan Charles, converted by Jayden Hayward, who also added a penalty.
Western Force moved into seventh place with one regular season round remaining and with a strong chance of reaching the play-offs for the first time in their history.
"Our first 20 was probably our best 20 of the year but we went up and down and it was good to get a win," said Hodgson.
"Next week's game with the Brumbies is a big game for us but we've put ourselves in this position and we're going to go down there and try to get the win for sure."
The Reds have long been out of the play-off race but have a chance next weekend to upset the Waratahs' run towards a home semi-final.
"We probably hurt ourselves a lot by missed opportunities and silly errors," said captain James Horwill.
"We couldn't get the flow of our game going and also they pressured us at the breakdown and we probably weren't efficient enough there."
