Motherwell hustled Aberdeen out of the Scottish Cup semi-final to reach their second final of the season.
Curtis Main and Ryan Bowman scored twice in two minutes in the first-half as Motherwell established their authority.
Aberdeen toiled, even as manager Derek McInnes sent on an array of attacking substitutes.
Main added a third after the break with a fine finish following a Kari Arnason mistake at the back.
Motherwell reached their first Scottish Cup final since 2011 with the victory, having also knocked Aberdeen out of this season’s League Cup on their way to losing to Celtic in the final.
It was a measure of Aberdeen’s grim afternoon at Hampden that their first shot on target – from Adam Rooney – did not come until the 62nd minute. They committed critical errors in defence, but Stephen Robinson’s side were alert and ruthless enough to take full advantage.
