WESTMEATH HIT THREE second-half goals to book their place in the Leinster SFC quarter-finals.
Callum McCormack, Shane Dempsey and Ray Connellan all raised green flags as the Lake County proved too strong for Louth in Drogheda.
John Heslin was in menacing form, kicking nine points as Westmeath set up a clash against Wexford in the last eight.
There was little to choose between the sides in the opening 35 and late scores from Ryan Burns and Declan Byrne left Louth just one point adrift at the break, 0-7 to 0-6.
McCormack and Dempsey struck a decisive blow with two goals inside six minutes of the restart.
And when Connellan hit a third to put Westmeath ahead by 3-11 to 0-13, it all but condemned Louth to a place in the qualifiers.
