South Australia 7 for 239 (Head 106*, Bird 4-51) lead Tasmania 91 (Triffitt 25, Sayers 7-46) by 148 runs
Chadd Sayers ripped through Tasmania before Travis Head cracked an unbeaten century to give South Australia a chance of squeezing into the Sheffield Shield final, after day one at Gliderol Stadium in Adelaide.
Having opted to bat, the Tigers were rumbled for a mere 91, with Sayers' 7 for 46 a new personal mark in first-class matches. Sayers claimed seven of the first eight Tasmania batsmen, while benefiting from tight supporting spells delivered by Daniel Worrall and Joe Mennie.
Only George Bailey, Tom Triffitt and last man Jackson Bird were able to make it into double figures, offering SA the chance to push for a major first innings advantage and an outright win.
SA lost regular wickets in their reply, but Head and Alex Ross helped their side forge ahead in the final session. Head's century followed his second-innings hundred, which guided SA to an unlikely fourth-innings chase against Western Australia in Perth.
That result kept SA in the race for the Shield final, and while they are reliant on other results in Alice Springs and Brisbane, they have given themselves a chance.
