South Australia are in the mire against Tasmania despite paceman Jordan Buckingham taking a career-best seven-wicket haul on day two of their Sheffield Shield match.
Tasmania, with Charlie Wakim scoring a polished 110, posted 381 all out in reply to SA's first innings of 307 at Adelaide's Karen Rolton Oval.
SA's top order crashed to 3-47 at stumps, trailing by 27 runs.
Buckingham had seemingly rescued the Redbacks with 7-71 from 23.1 overs after Tasmania's Wakim and opener Caleb Jewell (87) put the visitors in a position of power.
The pair featured in a 189-run stand, taking Tassie to 1-211 when Wakim slashed to backward point and Daniel Drew reeled in a spectacular one-handed catch.
Jewell followed 14 runs later, denied a century when, hooking a short Buckingham ball, the left-hander was caught at deep fine leg.
Beau Webster (62) and Matthew Wade (43) steadied before Buckingham, the 23-year-old born in Bundoora, Victoria, returned to mop up the tail.
In his 12th first-class game, the right-armer collected the final five wickets of the innings - the last six Tasmanians fell for only 67 runs.
Buckingham's command of line and length has already caught the eye of national hierarchy, playing two Australia A games and a Cricket Australia XI fixture.
But his SA teammates failed to ride the momentum he created, turning out another brittle batting display.
The Redbacks, who lost 4-19 in a first innings spell, collapsed to 3-10 in the eighth over.
Tasmanian quick Lawrence Neil-Smith (2-16) struck first, dismissing Henry Hunt (two) before his new-ball partner Gabe Bell (1-12) had Kelvin Smith (four) caught at slip.
Drew (one) lasted just five balls, outed by a canny off-cutter which trapped the SA batsman plumb lbw.
Captain Jake Lehmann, a first-innings centurion, is not out eight and Nathan McSweeney is on 28.
