Batting with the world's best batsman one day, a trip to Old Kings to take on a desperate Parramatta the next.

That's the journey young Manly-Warringah batsman Ollie Davies has been on this week as he prepares to return to McDonald's Men's Premier Cricket after debuting for the NSW Blues.

On Monday, the 20-year-old lived out the dream of cricketers around the world when he strolled out to bat with Steve Smith in the Blues' Marsh One-Day Cup against Victoria.

Davies immediately showed he belonged at that level, becoming just the 13th NSW player to reach a half-century in his first appearance in a one-dayer.

The power-hitting right-hander finished with 57 from 41 balls, sharing in an 89-run partnership with Smith at North Sydney Oval.   

"It's not every day you get to go out and bat with Steve Smith," Davies said.

"It's a bit surreal to think I got to bat with Australia's best cricketer. It was pretty cool.

"He just kept backing me and telling me to do my thing and to put it away if it's there.

"I don’t think it’s really hit me yet that I almost put on a 100-run partnership with Steve Smith.

"I was batting with Steve Smith one day and back to normal the next."

Davies will return to Premier Cricket on Saturday after a two-month BBL-enforced absence, considerably bolstering Manly's line-up for the trip to Parramatta.

He is one on a long list of NSW-contracted players to be released back to their clubs.

All 10 matches will be played under limited overs format after day one was washed out without a ball being bowled.

Manly need victory to maintain their position in the top three while a loss for Parramatta will officially kill off any slim chance they have of making the finals.

North Sydney's clash with Northern District at North Sydney Oval is another critical match.

Norths are one spot below fifth-placed NDs but have a stack of sides breathing down their neck.

Bankstown (eighth) and Gordon (11th) are two of those sides and their meeting at Bankstown Oval is of equal importance, as is the Easts (ninth) v Wests (12th) encounter.
