The Westmeath county champions booked their place in the Leinster semi-final on Sunday.
The Downs manager Lar Wall is crediting their early goal through Kevin O'Sullivan for their impressive victory over Ardee St Mary's.
The Westmeath champions were six points clear at half time, and finished with a final scoreline of The Downs 1-17 Ardee 12 points.
That result sets up a meeting with Ratoath of Meath who despatched Rhode on Sunday in an ill-tempered affair.
Speaking to Gerry Russell after the game Lar Wall says he's happy with both the result and performance:
