Ryan Edmondson scored a dramatic stoppage-time winner to lead second-place Carlisle to a 2-1 victory at Swindon and bolster their automatic promotion hopes.

Both teams struggled to create clear-cut chances in a first half lacking in quality in the final third.

Jack Armer came close to giving the visitors the lead, but his close-range effort was blocked on its way to goal.

Armer made amends with a superb finish to break the deadlock six minutes into the second half.

Swindon looked to have got off the hook when striker Charlie Austin headed against his own crossbar from a corner but the rebound fell kindly for Armer to rifle home from the edge of the box.

Swindon substitute Tyrese Shade looked to have salvaged a point with a calm left-foot finish from midway inside the penalty area 10 minutes from time.

But Edmondson broke Swindon’s resolve by heading in a corner with virtually the last touch of the game in the sixth minute of added time.
