Steve Smith has been left out of the men’s T20 squad World Cup for next month’s tournament in the Caribbean, signalling a shift towards a new era for Australian cricket.

But selectors chose not to include youngster Jake Fraser-McGurk despite 259 runs in six Indian Premier League matches including 84 off 27 in Delhi’s victory over Mumbai on Saturday.

Despite the omission of Smith, chair of selectors, George Bailey, said this was an “experienced” squad that “covers the scenarios the panel believes will factor in the West Indies.”

He said Smith and Fraser-McGurk were both part of “long conversations”, but his panel were limited to 15 players for the tournament.

“We will continue monitoring several players who have missed out on this preliminary squad and note that if we wish to change this squad, we have the option to do so over the coming weeks in accordance with ICC regulations,” he said.

The side is largely as expected, and is led by Mitch Marsh. It includes openers David Warner and Travis Head. First-choice fast bowlers Pat Cummins, Mitchell Starc and Josh Hazlewood are joined by Hobart Hurricanes’ Nathan Ellis.

Ashton Agar is back in the squad as back-up spinner behind Adam Zampa. Matthew Wade and Josh Inglis provide wicketkeeping options.

Marsh said it was a “good group of people” and a privilege to be named captain.

“We have had some strong success in recent times and I am hopeful that will continue in what looks like a wide-open tournament,” Marsh said.

Smith’s exclusion comes after limited T20 opportunities and a poor return from two matches against New Zealand in February. He made scores of 11 and 4 against the Black Caps opening the batting alongside Head.

Smith didn’t have the opportunity to impress selectors in the IPL, after he was overlooked in this season’s auction.

His comments after the New Zealand series suggested he anticipated his Australian T20 career might have run its course.

“I’m easy, I’m content where everything’s at in my career and what I’ve been able to do so if I’m part of the World Cup great, I’d love to be, but if I’m not then so be it,” he said in February.

Fraser-McGurk – who turned 22 last month – left his run narrowly too late, despite his recent IPL heroics.

At the start of last season he relocated to South Australia, and the move paid dividends.

In October he set a new record for fastest List A century, hitting three figures against Tasmania off just 29 balls. And he made his Australian 50-over debut against the West Indies in February, and hit 41 off 18 in his second match.

Back-to-back BBL MVP Matt Short was also overlooked, although Bailey noted he was another one who was among final cuts.
