The NSW Blues remain in a strong position against Queensland after another disciplined bowling performance in their Marsh Sheffield Shield match at the Gabba on Saturday.
By stumps on the third day Queensland was 5/186 in its second innings, a lead of just 51.
With the first session washed out extra overs will be bowled on Sunday, leaving plenty of time for a last day result, weather willing.
Once again the wickets were shared around. Harry Conway followed his five wickets in the first innings with 2-20 while Trent Copeland has 2-39 and Sean Abbott 1-44.
The main stumbling block for NSW is again new Test batsman Marnus Labuschagne, who is unbeaten on 48 after top-scoring with 69 for the Bulls in the first innings.
Keen to keep the game moving after a second rain interruption in two days, NSW declared on its overnight score of 9-288.
Copeland claimed the first wicket yesterday, trapping Matt Renshaw leg before wicket for 12.
Bulls captain Usman Khawaja was the second to go, caught behind off the bowling of Abbott for 24.
Queensland opener Joe Burns top-scored with a gritty 52 off 105 balls before he was caught by Steve Smith at second slip off Copeland.
Charlie Hemphrey (6) and Sam Heazlett (8) were both caught behind by Blues captain Peter Nevill off Conway in very different ways. Hemphrey went pushing outside his body at a delivery down the leg side and Heazlett nicked a regulation defensive shot.
After posting 125 for the Blues on Friday, David Warner is the only player to pass 70 in the match.
