South Australia's quicks have put their side in control against Tasmania as the visitors closed in on a 300-run lead at stumps on day two of their Sheffield Shield match in Hobart.
Tasmania were rolled for 149 in just 50.3 overs at Blundstone Arena, leaving them 180 behind on the first innings.
SA opted not to enforce the follow-on and expanded their lead to 291 by stumps, as they reached 4-111.
Daniel Drew was unbeaten on 54, having struck nine of his 76 balls for four, and Jake Lehmann two not out.
Veteran quick Jackson Bird (4-37) worked his way through the SA top order, having taken the last two first-innings wickets to finish with 3-68.
South Australia added 20 for the last two wickets early on day two to get them to 329, and their three pacemen took control of the game after Tasmania's openers put on 33.
Tassie lost 5-33 either side of lunch, with Brendan Doggett (4-21) causing most of the early damage, taking three of the first four wickets.
Fellow pacers Nathan McAndrew (3-51) and Wes Agar (2-50) maintained the pressure on a pitch offering some assistance for the quicks.
Jake Doran, who returned a positive COVID-19 test on day one, was the only home batter to get on top of the SA attack.
He scored 42 off 53 balls and put on 66 for the sixth wicket with Beau Webster (26) after Tassie were floundering at 5-66.
However, Doran's dismissal triggered another slump of 5-17 either side of tea.
