Reigning champions Team Bath fell to a 61-51 defeat against unbeaten Surrey Storm in round nine of Superleague.
The league leaders held a 29-25 lead at half-time but produced an impressive defensive display to keep the hosts at bay, while England shooter Rachel Dunn continued to dominate in attack.
But second-place Manchester Thunder kept up the pressure, winning 53-46 against Hertfordshire Mavericks.
Meanwhile, Team Northumbria and Yorkshire Jets battled to a 46-46 draw.
Round nine's final game will be played on Thursday between bottom club Loughborough Lightning and Celtic Dragons.
Surrey remain top of the standings with seven wins and two draw, and Thunder remain one point behind.
Team Bath, who earned a draw against Storm in round three, sit third on 17 points.
Bath captain and England mid-courter Serena Guthrie said after Monday's defeat: "Obviously we are disappointed to go down by 10 goals but Surrey are a good team and were never going to give many balls away.
"I feel we made a step up from where we have been playing recently and now we need to make a step up again in consistency. We need to be even more clinical."
