They now sit in third in the Allianz League table.
Westmeath were the convincing winners of the midlands derby in the Allianz League Division Two at the weekend.
They overcame Laois on a scoreline of 1-18 to 13 points at TEG Cusack Park in Mullingar.
The Lake County went on a seven point run to start the game and never looked back, John Heslin carried on his form for the club championship kicking six points in the opening 35 minutes.
It puts the Lake County into contention for promotion ahead of the final weekend meeting with Kildare.
A win against the lillywhites would see Jack Cooney's team into second place if Armagh don't match the result in their game with Clare.
Meanwhile Laois will need at least a point away to Fermanagh to secure Division two football.
Mike Quirke will be keeping a close eye on events in Clare and Cavan who are both in contention with the O'Moore county for the second relegation spot.
