NSW captain Peter Nevill spent almost an entire day out in the middle as players across the McDonald's Men's Premier Cricket competition battled heatwave conditions in round seven action on Saturday.
Nevill opened the batting for Eastern Suburbs against Blacktown Mounties at Waverley Oval, spending 314 minutes at the crease in making 137 before returning to the field shortly after his dismissal.
The Dolphins declared at 7-382 and have the Mounties 1-16 in reply.
Nevill's dig was just one of many heroic efforts as players in all games battled temperatures hovering around 40c.
Sutherland's clash with Western Suburbs at Glenn McGrath was abandoned for the day after 65 overs when the mercury nudged 43c.
The other nine games continued in energy-sapping conditions.
"The conditions progressively got worse as the day wore on, but if you play long enough you have these sort of days from time to time," Nevill said.
"Playing in India and Sri Lanka can be really oppressive, so this heat was uncomfortable but manageable in comparison.
"It was good to score some runs and help get the team into a position where we can win the game."
Nevill's ton – his 13th in Premier Cricket - was one of eight centuries on day one.
Manly-Warringah opener Joel Foster scored his first Premier Cricket ton, spending 406 minutes in the middle for a brilliant 160 against Northern District.
He clubbed five sixes and 14 fours in his breakthrough knock.
Teammate Jack Edwards made it back-to-back centuries, reaching 108 to help the Waratahs to 5-350 at the close of play at Mark Taylor Oval.
Randwick-Petersham's Daya Singh became just the ninth player in First Grade history to score a century batting at No.9, helping his side climb out of a hole against UTS North Sydney.
Sutherland's Tom Doyle celebrated his 100th First Grade match in style, scoring 102.
There were also centuries for Nick Larkin (Sydney Uni), Harry Dalton (Mosman) and Nick Stapleton (St George).
On a tough day for bowlers, Western Suburbs skipper Josh Clarke produced career-best figures of 5-69 against Mosman.
Ben Taylor's 5-28 for Bankstown against Campbelltown-Camden was the only other five-wicket haul.
Sydney University, Bankstown and St George all secured first innings points on day one.
