The Lake County were well beaten by Derek Lyng's Leinster champions.
Westmeath were "ran over" in their Leinster Championship opener according to the county's manager.
Joe Fortune watched his team succumb to last year's provincial champions in a first half that saw Westmeath concede 17 points, replying with just four of their own.
The second period followed along similar lines to produce a final score of 0-29 to 0-7.
A disappointed Fortune says the first half in particular wasn't good enough:
