Talking points: Cam Green's technical flaw exposed, Windies catching nightmare, third umpire's shocker performance

Two days into Australia's first Test against the West Indies, and the same problem has presented itself on both occasions: the top order.

With a new make-up, there's no doubt it's going to take time for the likes of Sam Konstas and Cameron Green to adjust.

But with the introduction of the World Test Championship, results matter and patience isn't a virtue.

Both Green and Konstas showed why at their young ages, there's a lot to improve on with their techniques as the West Indies fast bowlers continue to exploit them.

Here are the talking points from day two.

'Disturbing' pattern in Green's game

When the runs don't come, prepare for your technique to be scrutinised within an inch of its life.

That's the case for Cam Green who hasn't had a happy start at No.3.

In the first innings, Shamar Joseph bowled back of a length outside off stump, with the Aussie edging to gully. He was let off the hook, though, with Brandon King dropping the catch.

However, Green copped a similar delivery from Justin Greaves in the second innings and this time edged to Roston Chase at first slip who took the chance.

"Almost a carbon copy," Ian Bishop said on ESPN.

"Patterns in his game with dismissals are quite illuminating and disturbing at No.3."

Greg Blewett also made the observation Green is happy to leave balls that are fuller outside off stump but changes his attitude when it's shorter.

Former West Indies all-rounder, Carlos Braithwaite, made the point that Green is currently at a stage of his career where he's learning about new conditions.

"He's a proper unit and you normally associate tall guys with being front foot players but he loves to get back and punch the ball," he said on ESPN's Around The Wicket.

"In Australia I can only imagine that where he's trying to intercept the ball, he'd be hitting into it but in the Caribbean he's coming out in front a little bit away from his body as well so there's a little bit of adaptation (needed).

"I remember him mentioning one of the training sessions at Winward cricket club, which is one of the fastest pitches in Barbados, and he said it was a touch slow and I said Cam relax your expectations, that's the fastest in the island."

Windies fielding struggles continue

It was the Sam Konstas we knew from his first Test appearance on day two at Barbados.

The opener tried to charge the West Indies fast bowlers, just like he did to Jasprit Bumrah.

It wasn't coming off in the first over but fortunately for him, the West Indies couldn't catch.

Facing his eighth ball, he was dropped at third slip by John Campbell after charging down the wicket to Shamar Joseph.

"What does this young man have to do for them to take their catches? Seriously," a frustrated Ian Bishop said on ESPN.

Two balls later, Joseph was screaming catch again after an edge to second slip.

This time Justin Greaves dropped it.

"Oh my goodness me ... Shamar Joseph, he needs to go to church," Bishop said.

Coach Darren Sammy could be seen screaming with his reaction.

Eventually, Joseph did it himself by bowling Konstas for five.

Third umpire having a nightmare

If you're a West Indies fan or player, you'd probably like to start all over again with the DRS system.

Roston Chase's men have been on the ugly end of the decision making from Adrian Holdstock.

On the first day, Travis Head was given a reprieve after it was ruled Shai Hope hadn't caught the ball cleanly behind the wickets.

Then on day two, almost the exact type of catch came again with Alex Carey, from Hope's edge.

This time it was given out.

That wasn't the only DRS drama though.

Chase was given out lbw off Pat Cummins' bowling and it was reviewed straight away.

A clear deflection was seen on the replay, with ultra edge showing a spike before the ball reached the bat. It appeared to be out of sync considering the deflection.

However, Holdstock ruled there was a gap between bat and ball and gave it out.

Chase wasn't happy, walking off very disappointed.

Green faced a similar decision during his innings, with the ball appearing to hit the bat and pad simultaneously. He was given not out.

Speaking about the Chase decision, Braithwaite wasn't impressed with the officiating.

"This you can see with the naked eye that it was a clear defection, albeit the technology may have left you wondering, the naked eye shows you it was a clear deflection," he said.

"There's definitely a lack of consistency and I'm sure West Indies fans and players, myself, felt aggrieved during the course of play."

Post-match, Mitchell Starc admitted there appeared to be errors with the system.

"It sort of looked like the snicko and images were out of sync to some capacity, you might have to ask the umpires on how that's perceived from their end," he said.
