Kerry saw off the largely limp challenge of great rivals Cork in Division One of the Allianz Football League at Pairc Ui Chaoimh - the final scoreline of 0-13 to 0-11 somewhat flattering to the Rebels as Jack O'Connor's men made it four from four.
In front of 12,800, the Kingdom were always the better side and led 0-8 to 0-2 at the break with Declan O'Sullivan, who ended with a tally of five points, and Bryan Sheehan, who helped himself to one shy of Sheehan, operating at a different level to their Cork counterparts.
Elsewhere, James McCartan's Down recorded a fine 0-15 to 1-10 win over All-Ireland champions Dublin at Pairc Esler in Newry.
The visitors trailed by four points at the break, 0-8 to 0-4, but Kevin McManamon's 42nd-minute goal breathed new life into their challenge but in the end it was the hosts who chalked up their second win in as many weeks to move clear of the relegation zone.
In Portlaoise, Laois just about made home advantage count as they ran out deserving 1-15 to 1-10 winners against Armagh and in doing so eased their relegation worries.
The Ulster outfit trailed by four points at the break and their cause was not aided before the second-half when Ciaran McKeever received his marching orders for something he did while leaving the pitch at half-time.
To their credit the men from the Orchard County did not throw in the towel and Caolan Rafferty's goal gave them fresh hope but after getting to within two of their Leinster counterparts Paul Cahillane's riposte finally saw the O'Moore County over the line.
Meanwhile, Mayo's trip to Ballyshannon to face Donegal was not a worthwhile one as the hosts, for whom Colm McFadden, Michael Murphy and Patrick McBrearty starred from start to finish, ran out comprehensive 0-17 to 1-7 winners.
Enda Varley's 10th-minute goal looked to have set the Connacht champions on their way but that proved to be the highlight of the day for James Horan's men.
