A breakthrough century four years in the making, a 400-match celebration and a teenage all-rounder's five-wicket haul were among the highlights on day one of round six of McDonald's Men's NSW Premier Cricket.

Four teams – Bankstown, Sydney Uni, North Sydney and Sydney – posted 300-plus totals, but elsewhere bowlers enjoyed a day out as Randwick-Petersham, Blacktown Mounties and Parramatta were rolled cheaply. 

Manly-Warringah's Jack Edwards has scored a First Class and one-day century for NSW – as well as tons at under-17 and 19 national championship level – but had never raised the bat in Premier Cricket after debuting in 2016/17.

That all changed around 5.20pm Saturday when he sent a cover drive to the boundary to bring up three figures against Randwick-Petersham at Manly Oval.

With a big contingent of teammates and lower grade clubmates watching – along with brother Mickey and parents Phill and Sarah – a relieved Edwards (107) ended a four-year wait while putting his side in complete charge.

Replying to Randwick-Petersham's paltry 98, Manly is 5-230 and pushing for maximum points on day two. 

Many kilometres west, Fairfield-Liverpool skipper Jarrad Burke was presented with a memento in a pre-match ceremony before going about his job in First Grade game No.400.

The 37-year-old all-rounder picked up his 652nd career wicket as the Lions bowled Blacktown out for just 158 at Rosedale Oval.

Burke is just the sixth man to play 400 First Grade games.

At the other end of the age spectrum, Western Suburbs 19-year-old Connor Blaxall-Hill took the day's best figures - 5-116 – as the Magpies fought hard to bowl Sutherland out for 285 at Pratten Park.

Sydney's English import Stephen Eskinazi just keeps scoring runs.

The Middlesex professional scored his fourth Premier Cricket century to spearhead the Tigers' mammoth first innings total of 399 against UNSW.

Eskinazi cracked 18 fours and four sixes in his breezy 157, taking his total career run tally for Sydney to 1159 at 72.44.

And Tim Cummins received a 'well done' text message from brother and Australian Test star Pat after making 101 for Sydney Uni against Northern District.

The Students were 4-86 when Cummins walked to the crease but finished the day 9 (dec) 313 following the gloveman's patient 101.
