Both buoyed by mid-week wins
Rushen will be looking to make it three wins from three this season when they travel to The Bowl tomorrow (SATURDAY).
They head into their game with St Mary's on the back of a mid-week Old Firm triumph over Peel.
St Mary's meanwhile are in second place in the Canada Life Premier League after three matches and registered a big win away at Corinthians on Wednesday.
Goals from Jack McVey, Frank Jones and Craig Murphy helped them to a 3-2 victory at Ballafletcher.
