Hearts are a maximum of two wins away from clinching the Championship title after beating Raith Rovers 3-1 at Stark's Park on Tuesday night.
Kevin McHattie's opener was cancelled out by Craig Barr but Jamie Walker and Billy King scored for Robbie Neilson's men after Christian Nade had been sent off.
Third-placed Rangers were held to a 2-2 draw by Alloa at Ibrox. The Wasps went in front through Ben Gordon but a Nicky Clark double had Stuart McCall's men ahead, only for Liam Buchanan to level with eight minutes left as Alloa moved out of the bottom two on goal difference.
