The West End Redbacks are 0/26 in reply through openers Jake Weatherald (22*) and Henry Hunt (3*), after the quicks struck to bowl the Tigers out.
Joe Mennie (3-76) tore through the top-order and was ably supported by Wes Agar (3-68) after they won the toss and sent the hosts in to bat.
In his final first-class match for Tasmania, veteran George Bailey managed just seven thanks to Chadd Sayers.
The Tigers blunted the new ball to reach 1-60 at lunch but lost four wickets in the middle session.
Allrounder Simon Milenko proved the only resistance to the Redbacks whose first Shield century saved the Tigers from a lowly total.
Milenko shared a 57-run partnership for the ninth wicket with Gabe Bell (six) before being bowled by Will Bosisto, who is playing his first game for South Australia.
While we wait for the rain to pass, this was the moment Tim Nielsen handed baggy red 641 to Will Bosisto, and Callum Ferguson to West Torrens teammate Daniel Drew (642)! 🎓🕷 #SheffieldShield pic.twitter.com/QSrb6KUPCq— West End Redbacks (@WestEndRedbacks) December 7, 2019
Nick Winter also struck with a double breakthrough in the third session, bowling both Lawrence Neil-Smith and Jackson Bird to have the Tigers 8/190.
Off-spinning allrounder Daniel Drew is on debut for the Redbacks along Bosisto.
