Striker Rachel Williams helped Birmingham City beat Doncaster Belles 3-0 to move seven points clear at the top of the Women's Super League.
The former Doncaster player, who switched clubs in the close season, struck twice to remain the WSL's top scorer with eight goals in eight games.
In a match that was tighter than the scoreline suggested, midfielder Dunia Susi opened the scoring with a header.
Williams then scored from the spot before nodding in late on to seal it.
Susi capped a good start by Blues, heading home in the ninth minute after good work by her England colleague Laura Bassett.
But five minutes later, goalkeeper Marie Hourihan had to produce a fine diving save from Shelley Cox to keep the lead intact.
Williams hit her seventh goal of the season from the penalty spot following a 38th-minute foul on England winger Karen Carney.
Donny kept pressing, however, and midway through the second half Hourihan was forced into another good stop from Vicky Exley's powerful free-kick.
The home side were on the back foot for quite a spell, but victory was assured five minutes from time when Williams headed her second goal from a Jo Potter cross.
The result maintained the WSL's only remaining unbeaten record as Blues, in front of a crowd of 465, stepped into the second half of the season in great style.
