Hertfordshire Mavericks held Team Bath to a thrilling 49-49 draw in Superleague round 11.
In a battle between third and fourth place, the Mavericks went in 29-22 ahead at half-time.
The hosts snatched the lead and kept it until last final minutes of the game before Herts levelled, and Bath then missed a penalty in the dying seconds.
There were also wins for Manchester Thunder and Team Northumbria on Friday.
Northumbria eased to a 68-40 win over Loughborough, who have yet to win a game this season.
Thunder beat Yorkshire Jets 51-50 to stay second in the table, with Bath and the Mavericks occupying the final play-off places.
Herts are five points adrift of reigning champions Bath but stunned the hosts in the early stages of Friday's game by taking a four-goal lead.
Jess Thirlby's team levelled at 12-12, but as the Mavericks defence began to frustrate the opposition attack, Sophie Hakin and Kadeen Corbin performed well under the post at the other end to give the visitors a seven-goal cushion at the break.
Thirlby opted to make tactical changes - fit-again Stacey Francis was brought on as goalkeeper, while captain Serena Guthrie moved to wing defence from centre - and it made the difference.
Bath won five turnovers in the third quarter and pulled ahead, leading 40-37 with 15 minutes to go.
But Herts fought back yet again and drew level with only seconds remaining on the clock.
Late drama ensued when shooter Rosie Allison earned a penalty and unopposed shot, but the England international saw her attempt go amiss and her side had to settle for a point.
The remaining round 11 game take place on Saturday, as leaders Surrey host Celtic Dragons.
