Rain and an entertaining final-wicket stand have frustrated Victoria at Bankstown Oval, where NSW claimed a first-innings lead of 174 runs after being bowled out for 364 on day three of the Sheffield Shield clash.
The Blues resumed at 7-304 in Sydney on Saturday, having claimed the upper hand in the contest thanks to Moises Henriques' 141.
James Pattinson removed Pat Cummins (17) and Trent Copeland (15) in his opening spell, threatening to quickly clean up the tail and end the innings.
But light rain ensured no play was possible between 11.25am and 2.15pm (local time).
It ensured Nathan Lyon and Harry Conway's final-wicket stand, worth 37 runs, felt like an eternity for the Vics.
Lyon scored 18, with the highlight coming when he rocked back and pulled a short ball from Will Sutherland over the fence.
Conway, batting for the first time in domestic cricket since his concussion during a tour game against India, finished 12 not out.
Conway, renowned for his impersonations as much as being one of NSW's most promising fast bowlers, was typically lively at the crease.
The 28-year-old called loudly and confidently, left with gusto and even borrowed some of Steve Smith's mannerisms as he sought to process what the pitch was doing.
Mitch Perry ended the partnership with a teasing delivery that Lyon edged to keeper Seb Gotch.
