Manchester won 10-4 against Coventry, easing clear by scoring four times without reply in the third period. Annie Clapperton, top goal-scorer in the women's Super 5s last season, was on target with four.
Katie's Hesketh's three goals in the opening quarter set Liverpool Lizards on the way to a comfortable 12-7 victory over Sheffield Sharks while, in Division 2, Liverpool Liver Birds remained undefeated after a 16-2 hammering of Welsh Wanderers, with Molly Boniface-Ashton (8) and Charlotte Hopwood (5) contributing most of the goals.
Penguin Emperors also retain a 100 per cent record in Division 2, surviving a late scare against London rivals Otter Lutra to win 7-6. Otter recovered from 7-2 down late in the game.
Later, Otter outplayed Hucknall 17-1 to join Manchester at the top of the table with three wins from three matches.
