South Australia 329 (McSweeney 118, Weatherald 100, Siddle 4-59) and 4 for 111 (Drew 54*, Bird 4-37) lead Tasmania 148 (Doran 42, Doggett 4-21) by 292 runs

South Australia's quicks 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.

Daniel Drew was unbeaten on 54, having struck nine of his 76 balls for four.

Veteran quick Jackson Bird worked his way through the SA top order, having taken the last two first-innings wickets to finish with 3 for 68.

South Australia added 20 for the last two wickets early on day two to get them to 329, and their three quicks took control of the game after Tasmania's openers put on 33.

Tasmania lost 5 for 33 either side of lunch, with Brendan Doggett causing most of the early damage, taking three of the first four wickets.

Fellow pacers Nathan McAndrew and Wes Agar maintained the pressure on a pitch offering some assistance for the quicks.

"We spoke about bowling hard and heavy into the wicket and trying to make the most out of the divots that were there," Doggett, who had taken just four wickets in three previous Shield appearances this season, said. "Wes Agar did a great job along with Nathan McAndrew, we all put in our best efforts."

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 after Tasmania were floundering at 5 for 66. However, Doran's dismissal triggered another slump of 5 for 17 either side of tea.

"Throughout the day they constantly challenged our defence and got rewarded on a wicket that's still got a little bit of life in it," Tasmania captain Jordan Silk said. "Their bowlers hit the wicket quite hard and challenged our defence and unfortunately we weren't quite up to it today.

"I thought full credit probably goes to their bowlers and the way they were able to make us feel unsettled out there."
