The clash at Ferguslie’s Meikleriggs ground promises to be a cracker between the two Capital rivals, who have both had good summers.
And Morton, the 28-year-old spinner, said: “Ever since I was young I have been hooked on the Scottish Cup and always given it a lot of importance.
“I was lucky enough to play in a final with my dad [Willie, the former Scotland player] for Penicuik when I was a teenager in 2008 and, although we lost that one, it made me determined to get back to the showpiece game again.
“I then won the event with Heriot’s in 2012 and it will be a special moment for me leading out the team on Sunday.”
Stuart Davidson, now 46 and out of first-team retirement to spearhead the Grange bowling attack this summer, has played his part in a number of Cup triumphs in the past, including in 1998 when the Stockbridge men won the double.
“The blend of experience and youth we have in the team works really well and everyone is enjoying their cricket,” he explained.
“That is down to the likes of captain Preston Mommsen, [player/coach] John Blain and Neil McCallum who create a fun environment and a spirit which means everyone wants to learn and play for each other.”
