Dundee closed the gap on Ross County at the top of the division with a comfortable 3-0 win against 10-man Livingston.

Ryan Conroy opened the scoring after 19 minutes when he found space inside the box and fired a left-footed strike past Andrew McNeil in the Livi goal.

Kenny Deuchar had two great chances to level the scores either side of half-time. His weak header from six yards was easily stopped, while another shot cleared the bar from close range.

Deuchar's misses proved costly as Neil McGregor made the points safe for Dundee after 74 minutes when he converted a Conroy cross before visiting midfielder Mark Fotheringham saw red for a second bookable offence moments later.

Substitute Nicholas Riley added a third after 82 minutes when he met a Stephen O'Donnell corner with a thumping header.
