Green impresses as Webster creates fresh headache with five wickets; Smith notches fifty in dismal NSW display

Beau Webster has added to Australia's Ashes selection headache, taking a five-wicket haul for Tasmania in their Sheffield Shield clash against South Australia.

But the news wasn't as promising for teammate Jake Weatherald, who again failed to go on with a promising start and was dismissed for 30 on Tuesday afternoon.

Weatherald scored just 23 in the Tigers' first innings and their second dig was his last chance to impress George Bailey and the selectors before the first Test, but he came undone after chopping on a Liam Scott delivery for the second-straight time.

Earlier in the day, Webster finished with figures of 5-50 from 13 overs as he tore through the Redbacks' middle and lower order.

Alex Carey was the only SA player to show some resistance, notching a half-century - but it was Webster who had the most at stake and he produced results that will make George Bailey's life even more difficult before the Ashes series opener.

The man who could potentially be picked ahead of Webster however is Cameron Green, who returned to the bowling crease for WA against Queensland and made an impact.

He dismissed opener Angus Lovell, with back-up Test keeper Josh Inglis taking the catch behind the stumps and bringing Marnus Labuschagne out to the middle.

Green took 1-13 from his first eight overs as Matthew Renshaw - who was overlooked for the Aussie squad - brought up fifty, while Labuschagne got off to a strong start.

The 26-year-old was bowling with real pace and looked to be back to his best after plenty of question marks surrounding his fitness to bowl.

In the other Shield game, a patient approach meant little for Sam Konstas on Tuesday afternoon, with the young gun knocked over by Scott Boland at the SCG.

The opener struggled to get his now-former Test teammate away in the first session of play but survived through to lunch alongside partner Ryan Hicks.

But once injury replacement Hicks (16) fell to off-spinner Todd Murphy after the break, Konstas would soon follow when Boland produced a peach to dismiss his NSW rival.

The ball from the Victorian split the gap between Konstas' bat and pad as the right-hander was sent back to the pavilion for 12 off 59 balls.

Konstas has now been dismissed by Boland on six occasions at domestic level.

It continues a tough start to the season for the 20-year-old, who has struggled for runs and was left out of Australia's squad for the first game of the Ashes series.

His departure allowed Steve Smith to trot out to the crease in Sydney and he looked to pounce immediately, dispatching a boundary from just his second ball.

Smith brought up his half-century from 75 deliveries as he gears up to take on England, but the NSW batters continued to fall around him throughout their first innings.

He was dismissed for 57 as the Blues were rolled for 128 in the final session of day two, trailing the Vics by 254 runs after a dismal first innings.

Mitchell Starc claimed the early wicket of Harry Dixon in the visitors' second innings.
