A five-wicket haul to Piers Robinson late on Saturday has given Waratah-Mayfield a chance of an upset victory over defending champions Wests.
The 21-year-old seamer from England finished with figures of 5-21 off six overs as Wests ended up 5-52 at stumps on day one at Waratah Oval.
The fifth-placed Rosellas, who have already lost Joseph Price (9), Aaron Wivell (21) and captain James King (0), need a further 100 runs this weekend to secure first-innings points.
Josh Emerton (16 not out) and Edan Brichta (6 not out) are the unbeaten batsmen.
Earlier in proceedings Waratah were dismissed for 151 inside 78 overs.
Across at No.1 Sportsground and Matt Willett took season-best figures of 6-33 from 27.3 overs, featuring 12 maidens, as Cardiff-Boolaroo bowled Newcastle City out for 173. Cardiff are 0-11.
And at Kahibah Oval some rearguard action from Charlestown’s tail saw the hosts reach 272, including 61 runs for the last two wickets, after Sri Lankan import Sashreeka Pussegolla top scored with 71 at No.4. Wallsend are 1-33 in reply.
Wet weather on Friday night meant there was no play in the remaining Newcastle District Cricket Association first grade fixtures at Ron Hill Oval, Cahill Oval or Lynn Oval.
The top-four clash between Toronto and University, the meeting of Belmont and leaders Hamwicks as well as Merewether visiting Stockton will now take place this Saturday but still under two-day laws.
The team batting first can face a maximum 45 overs.
