St. Johnstone moved six points clear at the top of the William Hill Championship after being held to a 0-0 draw with Raith Rovers.
Saints had the best chance of the match with Josh Fowler striking the crossbar before Sam Stanton's goalbound effort struck Fowler and bounced out.
The result moved the Perth men on to 50 points with closest challengers Partick Thistle due to face Airdrieonians on February 22.
Rovers sit on 30 points, enough to put them in fifth position but Greenock Morton can overtake them by picking up points against Queen's Park.
