Marist College are into the Connacht Schools Senior Cup Final after beating Coláiste Einde yesterday afternoon.
The win now means the Athlone school have extended their unbeaten record for the year and are now just 70 minutes away from a league and cup double.
The midlanders held a commanding 22-3 lead at the break and despite a brave comback from their Salthill counterparts, Marist held on to close out a 32 to 17 point win.
Marist will now play the winners of Garbally College or Sligo Grammar who meet later today.
