The club has launched an exclusive ticket + pint + programme deal, which can all be got for the price of £10.
The offer is only available on Sunday from midday at the Mountain Ash RFC clubhouse on 16A Oxford St, Mountain Ash CF45 3PL.
“I hope that all Scorpions and Rochdale fans who like a pint before the game take this offer up,” said Grady.
“It’ll be great to see them in the club house after the game too – I’m always willing to have a chat with fans and it’ll be a great atmosphere while watching Magic Weekend games.
“We’re all looking forward to Rochdale coming to town on Sunday.
“We know it will be a tough game but there’s a lot of competition for places in our side right now and I know all the players will give 100 per cent as we look for our first home win this season.”
