Motherwell made their first Scottish Cup final for 20 years after a first-half demolition of St Johnstone.
Stephen Craigan nodded the Steelmen in front after just five minutes when Saints goalkeeper Peter Enckelman failed to deal with a corner.
It was Jamie Murphy who doubled their lead soon after with a fine run and low shot leaving the keeper helpless.
John Sutton sealed the win before the break with a superb volley from around 30 yards.
Motherwell will play either Aberdeen or Celtic who play tomorrow afternoon.
Congratulations to Motherwell!
