Manchester Thunder produced a sensational second-half comeback to beat Loughborough Lightning in the Superleague third round at Belle Vue.
An injury-hit Lightning looked set for a third straight win over the champions but Thunder, playing in front of a club home record 1,951 fans, won 67-54.
Unbeaten Thunder are level on points with Team Bath and London Pulse at the top of the table.
"Wow, my nerves are shot," Thunder head coach Karen Greig said.
"It certainly wasn't pretty but my team showed great resilience and unity to pull it back.
"Loughborough certainly brought it today, they spilled very little and made it hard for us."
The hosts found themselves 12 goals down midway through the third quarter following a stuttering attacking display, which was in contrast to a diligent and composed performance from Lightning.
Eight goals adrift heading into the fourth period, Thunder swiftly began chipping away at the lead, as a youthful Lightning - who were missing a number of experienced players including England's Natalie Panagarry due to injury - began to crumble.
The Black and Yellows outscored the visitors 21-9 in the final period, with the calm heads of player-of-the match Laura Malcolm and Caroline O'Hanlon in the centre court key to the remarkable turnaround.
Two late intercepts from wing defence Amy Carter and defender Becky Airey and the flair of shooter Ellie Cardwell were also central to Thunder's fightback.
Lightning head coach Sara Bayman says the result is "pretty devastating" but that she will take "lots of the positives" and hopes her side's first-half performance will "be the catalyst" for the rest of the season.
"Thunder are a quality side but it was in our control and we have to learn from this so that next time we can close the game out," former England centre-courter Bayman said.

They were cheered on by tennis coach and former Fed Cup captain Judy Murray, who was delighted to meet Sirens mascot Serena...
In the final fixture of the round on Monday, London Pulse beat Celtic Dragons 69-38 to secure their third consecutive victory, which surpasses their total win tally of two from the whole of last season.
