The top two sides in JCK Division Two are on course to meet each other in the final of the GH Corlett Woods Cup on Good Friday, April 22nd.
Runaway leaders St John's booked their place in the last four with a 3-2 win against Ramsey Youth Centre, while second placed Union Mills had a 5-1 away victory at Braddan.
Two goals from Stephen Glover and one from Callum Gallagher saw St John's through, with Steven Jordan getting both goals for their opponents. St John's led 2-1 at half-time.
Second placed Union Mills effectively killed off their tie in the first half, during which they scored four times without reply. Steven Quine (2), Gareth Logan, David Thommeny and Kenny Magee were the players on target, with Will Smith replying for the home side.
Marown had already made it through to the semis, and in the fourth quarter-final tie Colby won 2-0 at Foxdale. They benefitted from an own goal in the first half, and Steve Kelly got the second after the interval.
The draw for the semi-finals was made on Manx Radio on Saturday evening. In the first tie Colby will entertain Union Mills, and in the other match Marown will be the visitors at St John's.
Both those ties will be played on Saturday, March 19.
