Jamie Walker's first-half goal was enough to give Scottish Championship leaders Hearts victory over Livingston and take them 20 points clear.

The midfielder scored at the second attempt after initially being denied by goalkeeper Darren Jamieson.

Jamieson had saved earlier efforts from Walker and James Keatings and Prince Buaben missed chances for Hearts.

Livi's Nejc Praprotnik was sent off for receiving a second booking with 16 minutes remaining.

Genero Zeefuik and substitute Billy King squandered good opportunities towards the end but it mattered little as Hearts extended their advantage over second-place Hibernian, who beat Rangers to move up the table on Friday evening.

Callum Fordyce had gone close to giving Livi the lead in the first half, his header from a corner hacked off the line, and they remain three points adrift at the bottom of the table.
