The NSW Blues are chasing their third successive victory to start the Marsh Sheffield Shield season in a tight match against South Australia at the Adelaide Oval.
South Australia is 1/1 at stumps in its second innings needing a further 297 on the final day to claim victory. It would be the highest score of the match after NSW was bowled out for 253 on Sunday.
The Blues received a late boost when Josh Hazlewood trapped Jake Weatherald leg before wicket for a duck with the second ball of the innings.
Earlier, Trent Copeland joined the late great left-arm spinner Johnny Martin in equal eighth on the all-time list of leading wicket takers for NSW in First Class cricket with 291 scalps.
Opening batsman Nick Larkin was the glue that held the Blues’ second innings together, scoring 91 from 143 balls with nine fours and a six.
Larkin featured in a steadying 70-run partnership with Moises Henriques, who was dismissed for 38 when well set.
Larkin put on another handy stand with debutant Matt Gilkes (30), adding 72 runs and taking the visitors to a commanding 3/184 before the Blues lost their last seven wickets for 69 runs.
In a match dominated by seamers SA paceman Chadd Sayers collected career-best bowling figures. His 5-67 gave him match figures of 13-131.
NSW, seeking a third-consecutive victory to open their Shield campaign, made 289 in their first innings before bowling South Australia out for 245.
Seamers Harry Conway and Copeland claimed three wickets, spinner Nathan Lyon returned 2-45 from 22.2 overs and his Test teammate Josh Hazlewood 1-60 from 24 overs.
