Leeds United and Southampton will compete for the last Championship promotion spot.
Following the Saints’ 3-1 victory over West Brom on Friday night, this was verified.
After the first leg ended in a scoreless draw, Southampton won the second leg at St Mary’s to advance to Wembley.
In the second half, Will Smallbone and Adam Armstrong’s double put the Baggies to the sword, winning the semi-final match late on.
The Baggies, who will now play in the second division for a third straight season, received a late-game consolation goal from Cedric Kipre.
On Sunday, May 26, Southampton will play Leeds in the championship match; the victor will advance to the Premier League for the following season.
