The Giants received a mighty 'kick up the bum' with a surprise 56-53 loss to the Queensland Firebirds in Sydney on Friday night.
But goal shooter Jo Harten says her side remain focused on securing a top-two finish when the Super Netball regular season winds up next week.
The competition frontrunners trailed from start to finish against a hard-working Firebirds side eager to keep their slim finals hopes alive.
The Giants stormed back from a nine-point third quarter deficit to set up a tight finish, but they lacked the fluency necessary to overcome the visitors' tireless defensive work.
The loss leaves the Giants in peril of falling to third on the ladder if the Melbourne Vixens and Sunshine Coast Lightning win their respective matches on Saturday.
Finishing third would mean the Giants would lose the right to a 'double chance' in the finals.
'It was a great fightback from the girls, but we left it way too late,' England representative Harten said.
'The Firebirds got well ahead in the early part of the game and deserved to win tonight.
'They disrupted our flow, disrupted our timing.
'They really got into the spaces we wanted to put the ball. They played well, forced us into too many errors.
'But I think we can take responsibility for that ourselves.
'We didn't look enough, we didn't have the right options to deliver the ball to.
'I think that's a bit of a kick up the bum for us.'
The Giants face the high-flying Lightning next round in a game that will decide the structure of the top four.
'It will be huge for us,' Harten said.
'We don't want to slip into that third and fourth place in the top four. We want to contest that first game.'
Giants coach Julie Fitzgerald said playing a highly-fancied team was a good opportunity heading into playoffs.
'You want to play the best teams coming into finals,' she said.
'And you want to know that you've got the game there.
'So, tonight we will learn lessons and hopefully we'll be able to do better next week.'
