South Australia 2 for 222 (Weatherald 110*, Smith 62) lead Tasmania 98 (Sayers 6-32) by 124 runs
Jake Weatherald celebrated his 22nd birthday by flying to his maiden first-class century at Adelaide Oval, where Chadd Sayers had earlier demolished Tasmania to leave South Australia firmly in command at stumps on day one. Sayers picked up 6 for 32 as the Tigers were rolled for 98, before Weatherald and his opening partner Kelvin Smith cruised past that total without the loss of a wicket.
Smith was eventually caught off the bowling of Jackson Bird for 62 and Callum Ferguson was dismissed for a duck by debutant Cameron Stevenson, but Weatherald motored on to finish the day on 110 from 116 deliveries, alongside Travis Head on 37. It meant South Australia ended at 2 for 222, already with a 124-run lead.
Tasmania had won the toss and chosen to bat, but not one of their batsmen reached 20. Joe Mennie, released from his 12th man duties in the Perth Test so he could bowl in Adelaide, picked up two wickets, and Daniel Worrall also collected two, but Sayers was the man who wreaked havoc.
Sayers, who had been part of Australia's Test squad in New Zealand earlier this year, finished with six wickets from 16 overs. Only once has Sayers claimed better first-class figures, when he took 7 for 46 in March this year - also against Tasmania.
