Remembering former Westbury cricketer Isaac 'Maxi' Walters, the Make Runs Maxi foundation began four years ago and has since campaigned heavily to promote social and emotional wellbeing.

Saturday's 10.30am clash at Westbury will see the home side play in special guernseys, a fundraising raffle and the Isaac Walters spirit of the game award presented to the man of the match.

Make Runs Maxi board member Jodie Mansell said she was excited to see Mowbray join the cause in 2020.

"Blake Cassidy is one of his best buddies, hence the relationship between Westbury and Mowbray," Mansell said.

"It's nice that the guys want to do this and support Make Runs Maxi, but also honouring Isaac who's their mate.

"Next year we've got a lot of things planned [as a foundation], we're looking at really focusing on young people - getting into schools and doing more work with younger people."

On a two-game winning streak, Westbury will make one change for the clash which forms one of the biggest weekends on the club's calendar, with Alex Jordan replacing Corey Briggs.

Skipper Dan Murfet said his side was eager to perform.

"The Make Runs Maxi Foundation holds a pretty sentimental place for the club in general," Murfet said.

"A lot of the players knew Maxi quite well on both teams, so the charity holds a good place in our hearts and it's really good that Mowbray have jumped on board.

"I think it's something we'll try and make sure we do every year and it's good that now it can coincide with this mental health round that is a focus this weekend."

Reigning one-day champions, the Shamrocks have netted bonus points in consecutive weeks to occupy third spot on the ladder.

Last weekend's thumping win over Sheffield came in part from the bowling performance of spinner Alex Kerrison, who finished with the incredible figures of 4-2 off 10 overs.

"It was awesome - I didn't realise until we got off the ground what his figures were," Murfet said.

"I said 'do you realise how many runs you went for?' and he just nodded at me.

"To go for two runs off 10 overs is unbelievable, let alone to take wickets at the same time.

"He's bowling really well, he's gone back to what he used to do when he was a bit younger - bowling a lot quicker with his change up ball being a slower one.

"He's putting a lot of pressure on batters and it's pretty difficult to handle at the minute."

Mowbray have made one change with Spencer Hayes returning from Raiders to cover the absence of paceman Ben Spinks.

Eagles skipper Luke Scott has been one of the competition's most consistent batsmen, with just one failure among scores of 47, 68, 41, 61 and 50.

The classy left-hander said the shield match would be a special occasion for his team.

"We've got a few players that went through St Pats with Isaac so it was a pretty important one for us to jump at the chance to be involved," Scott said.

"It's a great cause and something everyone should try and be a part of."
