Eslöv won the match series 2-0 after tonight's win in Liljeholmshallen in Stockholm.
It was in the World Cup runner-up Möregårdh's second match, the one against Harald Andersson that he was warned and received a yellow card after throwing the racket on the floor after losing the first set.
Möregårdh also lost the second set but was able to turn around and win after three convincing final sets.
In the final, Halmstad, who won in Söderhamn with 4-0 and the match series with 2-0, is waiting.
The final series will be played April 13-16.
