Rookie South Australia opener Henry Hunt has notched his second Sheffield Shield century in as many innings on a day when teammate Travis Head missed an opportunity to push his Ashes credentials.
The 24-year-old Hunt hit a dogged 134 from 236 balls at Bellerive Oval on Thursday against Tasmania, propping up the Redbacks' first innings of 220.
In reply, the hosts reached 3-102 at stumps on day two.
Hunt now has five centuries from 20 first-class appearances, including 108 against Western Australia in Adelaide a fortnight ago.
Only two other South Australians made it to double figures on a green-tinged pitch.
"It's probably one of my better ones in terms of the conditions. It was one of the more difficult wickets, especially with the new ball," Hunt said.
"Any first-class hundreds are a hard hundred but these ones are nice, when you grind and the patience pays off at the back end.
"I've worked quite hard over the winter, so it's nice to see some rewards come through."
Captain Head was among three batters to fall cheaply in the morning session as his side wobbled to 5-111 at lunch.
Head, one of several players fighting for a middle-order spot in Australia's Test side for the December 8 series-opener against England, was bowled for 14 by an inswinger from Lawrence Neil-Smith.
Head managed just nine and 21 in his side's last-start loss to WA but notched a half-century against Queensland and 163 against WA in the proceeding games.
Hunt resumed on Thursday on 14 with his side 2-27 after only 15.1 overs were possible on day one due to rain.
He brought up his century with a push into the covers and was the last man out when he was caught behind off offspinner Jarrod Freeman on the stroke of tea chasing quick runs.
Evergreen veteran Peter Siddle was the pick of the Tasmanian bowlers, finishing with 4-42 from 24 overs.
The 36-year-old struck back-to-back blows with the wickets of Australian representative Alex Carey (six), who was caught at point driving outside off stump and Harry Neilsen (0).
Tasmania's Charlie Wakim reached 68 but was bowled by Nathan McAndrew in the final half hour of play.
