Raith opened their Ladbrokes Scottish Championship campaign with a comfortable 3-0 victory over Livingston.Rovers never looked back after taking an eighth-minute lead through Mark Stewart, while Ryan McCord's penalty later on in the first half and Mitch Megginson's strike in the dying stages saw them make an ideal start to their league season.Livingston, who avoided relegation last season on goal difference alone, were behind inside the first 10 minutes when Craig Wighton's shot deflected into the path of Stewart to slot home.It got worse for the visitors when defender Craig Sives was adjudged to have fouled Stewart in the area. The decision seemed harsh but McCord made no mistake with his penalty.Raith made sure of an emphatic win in the first minute of time added on as James Craigen picked out Megginson and the substitute striker, with his back to goal, turned and fired past Livingston goalkeeper Darren Jamieson.
