Henry Hunt scored his maiden Sheffield Shield century as part of a record-breaking opening partnership for South Australia on Monday.
The Grenfell junior combined with Jake Weatherald to post 293 for the first wicket, Hunt departing on 132 during the 79th over of the opening day against Tasmania at Adelaide Oval.
It was Hunt's highest score in his short four-game Sheffield Shield career, and the biggest opening partnership in South Australia cricket history, eclipsing Les Favell's and John Causby's 281-run stand in 1967.
It was also the biggest first-wicket partnership the competition has seen since Victoria pair Matthew Elliott and Jason Arnberger scored 353 in 1999.
Weatherald remained 195 not out to lead South Australia into a commanding position at 1-359 at stumps.
Hunt, speaking to media after the day's play, said it was "pretty cool" to be a part of a record-breaking partnership.
"It's pretty cool I reckon. We both worked hard in pre-season, it's just a good moment for both of us," he said.
"It's been a pretty good opportunity so far to whack the colours on with the South Australia boys. I've loved every minute so far since I've come over for pre-season. Obviously playing games has been really enjoyable.
"My goal is to bat as long as I can and work around the other blokes. Luckily I did it today."
He said he's taken onboard advice from South Australia high performance manager and former Australia coach Tim Nielsen.
"Tim Nielsen gave me some advice before my debut and that was to play the ball not the bowler so that's been my mentality the last four games," he said.
"It's been different, obviously facing first string bowlers like Hazlewood, Lyon, Holland, Pattinson the last few weeks has been challenging, but I've taken a few things out of that to try and build on my game. At the moment it feels good."
The Shield match was still continuing on Thursday afternoon at the time of publication, with South Australia looking to notch their first win of the season after two losses and a draw to start the year, Tasmania chasing just over 200 runs with eight wickets in hand.
