A solitary first-half goal gave leaders Celtic the points in their Development League fixture against Hearts at Riccarton.
There were no over-age players in either line-up and it was Celtic who began the brighter. However, it was Hearts who had the first two serious attempts at goal with Angus Beith firing a shot well over the crossbar and Alistair Roy hitting an angled shot just past the post.
The visitors opened the scoring on 29 minutes, central defender Jamie McCart netting a Joseph Thomson free-kick at the back post.
Six minutes later, Hearts keeper Kelby Mason produced a brilliant save, turning a Sam Wardrop header over the crossbar.
Hearts came more into the game towards half-time with Beith again hitting an effort too high and Ian Smith sending a strong angled shot just past a post.
The home side began the second half strongly and, within 15 minutes, had two efforts cleared off the Celtic goal-line, Fiacre Kelleher stopping a Beith shot while Robbie Buchanan had an effort from the rebound deflected just past the post.
Six minutes later, Lewis Moore also had a header cleared off the line as Hearts dominated.
On 73 minutes, substitute Russell McLean hit a shot against the post following a Moore corner, but this was Hearts last serious attempt at goal as Celtic finished the contest on top.
