Goals fom Alex Burns and David Bingham were enough to send Livvy back to the top of Division One as they ran out 2-0 winners against Ross County.
Burns opened the scoring in the 12th minute when he fired a ball home from eight yards following a goalmouth scramble.
Craig Taggart missed County's best chance of the half in the 24th minute when he rounded keeper Neil Alexander, but defender Graham Coughlan put him off his stride and the shot ended up wide of target.
County competed better in the second half and almost grabbed an equaliser in the 67th minute when John Fraser got on the end of a John McQuade cross, but Derek Holmes blocked his team-mate's header right in front of the goal.
Bingham put the result beyond doubt in the 83rd minute when he headed home a Steve Tosh corner.
