The Lake County are 70 minutes away from a provincial decider.
Westmeath Footballer Luke Loughlin says players "had a point to prove" following their win over Meath yesterday.
The Down's man finished with six points as his side secured a 4-18 to 25 points win against the Royal's in the Leinster Quarter-Final.
Matthew Whittaker and Shane Corcoran scored their side's two first half goals, with Corcoran adding another in the second half, before victory was sealed thanks to a Danny McCartan strike in the final minute.
Victory for the Lake County means they will now face Kildare in the semi-finals.
Loughlin says a performance was needed in order to win:
