Shrewsbury Town defender Aristote Nsiala headed a late winner as the League One leaders overcame Fleetwood.
The central defender crowned an impressive performance when he nodded home Shaun Whalley's 89th-minute corner for his second goal of the season.
Shrewsbury, the only unbeaten team in the EFL this season, have now won 11 and drawn four of their 15 matches.
Home skipper Abu Ogogo had an early effort blocked before Whalley's low shot was comfortably gathered.
Alex Rodman then fired a half volley off target for the hosts before Shrewsbury ended the half strongly when Junior Brown twice went close.
The left-back's 20-yard drive was held by Cairns before the Fleetwood keeper stopped Brown's header from Whalley's corner.
Kyle Dempsey fired wide for Fleetwood just after the restart before Shrewsbury twice called Cairns into action to save first from Carlton Morris, then Whalley.
Ogogo then went close to a breakthrough for the home side when he volleyed just wide before Nsiala's decisive 89th-minute winner kept Paul Hurst's men top, two points clear of Wigan - and now 10 clear of the chasing pack.
