Third-place Team Bath beat Manchester Thunder 55-51 to move within two points of their Superleague rivals.
The hosts had only lost once prior to Monday's round 10 match, but were punished for their slow start against the title-holders.
Bath built a seven-point lead at the break, going in 33-26.
And although Manchester fought back to cut the deficit to two, England goal attack Pamela Cookey guided the visitors to victory.
Team Bath head coach Jess Thirlby said: "I'm really proud with our performance. We started much better and we led for the whole 60 minutes against a top team.
"Although they came back at us, we never quite let them come level with us. We played well as a team. We have to have a contribution from everybody out there and we did that."
Bath kick off round 11 on Friday night at home to fourth-place Hertfordshire Mavericks, while Team Northumbria face winless Loughborough Lightning.
League leaders Surrey, who have already qualified for the play-off semi-finals, welcome Celtic Dragons on Saturday and Thunder travel to Yorkshire Jets on Monday, 31 March.
