Rovers Ladies moved up to third in the table following a 2-0 win over Sporting Club Albion.
Goals either side of half-time from Lynda Shepherd and Saffron Jordan secured the points for Gemma Donnelly's side, who have now kept four successive clean sheets.
Rovers started strongly, twice going close in the early exchanges, before Sporting struck the woodwork and had a goal disallowed for offside on the follow-up.
Shepherd then fired over the bar, before another Sporting shot went just wide.
Alex Taylor was then denied by the Sporting keeper, before Rovers took the lead on 41 minutes. Holbrook delivered a free-kick into the box and Shepherd headed home her third of the season.
The visitors almost equalised just before the break, following a long ball over the top and shot, but Jo Hutcheson pulled off a superb one-handed save.
Rovers doubled their lead midway through the second half, as summer signing Jordan scored her first goal for the club.
The hosts looked to extend their advantage, as Millie Chandarana fired just wide from a free-kick, before Natasha Fenton fired just over the bar.
Jordan was a thorn in the visitors' side late on, as she was dragged down by the last Albion defender, who was lucky to stay on the pitch, before firing wide of the target after Taylor played her in.
A delighted Donnelly said: "We controlled the game from start to finish. Albion provided very little threat, other than when Sophie Flynn slipped and they hit the woodwork.
"I thought that the substitutes did brilliantly when they were required to do a job against a very physical side.
"They are probably the best team we've played so far in terms of mixing their direct style with a bit of quality, but we really did play some superb football and we've got to be happy with another clean sheet."
ROVERS: Hutcheson, Kinvig, Bickett, Chandarana, Flynn (Taylor 30), Shepherd, Holbrook, Fleming (Fenton 46), Jordan, Johnson, Sheen (Boyle 68).
Subs not used: Maher.
