Motherwell only won one of their opening 10 Fir Park matches in all competitions this season - a 4-1 victory over Inverness. But they have now scored 15 goals in five home SPL matches and collected 13 points which helped them leapfrog the Highland side.
Michael Higdon netted a double - the first a tap-in on the half-hour mark and the second a wonderful first-time volley from the edge of the box in the 56th minute. Nicky Law grabbed the second with a typical burst into the box and good skill and persistence and Motherwell enjoyed a comfortable last half-hour.
McCall said: "That's us in the last five (home) games we have averaged three goals.
"You were asking, and had every right to ask, coming into December about our home form. Thankfully just like last season we have turned it round.
"We are not only winning games but we would like to think we are entertaining as well and scoring goals to boot."
Meanwhile, McCall played down anticipation that free agent James McFadden could re-sign for Motherwell after returning to the club to train.
The 29-year-old spent several weeks with his former club in the summer before moving to Sunderland after talks with Motherwell chief executive Leeann Dempster failed to come to fruition but is again looking for a club.
McCall said: "We have had Marc Fitzpatrick in with us, we have had Jim O'Brien in with us, I think the young boy (Paul) Slane might be coming in on Monday to train with us. We are just an open house.
"There is nothing to speak about on my point of view at the moment."
