Manly-Warringah captain Jay Lenton has declared his team is in better shape than ever to get through the BBL period and stay on track to reach the McDonald's Men's Premier Cricket finals for the first time in six years.

The Waratahs (26 points) sit alone at the top of the table after beating the previously unbeaten Bankstown in Saturday's limited overs clash at Manly Oval.

Sydney Uni (21), Sydney (20), Randwick-Petersham (20) and Northern District (20) all kept the heat on with wins in their respective games, but Bankstown (15) slipped from second to sixth after its 48-run defeat to Manly.

Manly made 9-242 from their 50 overs on the back of half-centuries to Cameron Merchant and Ollie Davies before bowling the Bulldogs out for 194.

"It was a bizarre game of cricket - it ebbed and flowed all day – but that's a huge win for us," Lenton said minutes after belting out the club's victory song.

"We have lost games like that in the past but it makes me very happy that we stuck with it and beat a quality side.

"They got on top of us at various stages but I couldn't be prouder of the way we fought through it."

The Waratahs will lose Davies, Jack Edwards and Steve O'Keefe to the BBL, but Lenton is confident it won't be a massive disruption.

Lenton said: "Our depth is pretty good and we've some points in the bank, so I think we're in a lot better position to get through that period than we have been in the past."

Sydney's total of 355 against North Sydney fell just 10 runs short of the record 50-over score in Premier Cricket.

No.3 Anthony Mosca led the way with an even 100, ably supported by opener Ryan Felsch (69) and English import Stephen Eskanazi (75).

The Bears made 9-272 in reply.

Gordon's Tym Crawford scored his second century of the season – and the sixth of his career – to spearhead his side's win over Mosman.

Arjun Nair showcased his all-round qualities, making 65 and taking 5-36 as Fairfield-Liverpool beat Hawkesbury by 23 runs.

And St George was a comfortable victor over Sutherland in the southern derby at Glenn McGrath Oval.
