Teenage sensation Sam Konstas was handed a maiden call up as Australia on Friday dropped rookie opener Nathan McSweeney for the final two Test matches of the Border-Gavaskar Trophy against India.
The 19-year-old is set to become Australia's youngest Test batting debutant in over 70 years.
Konstas' inclusion follows a series of disappointing performances from the Australian top order in the first three Tests especially McSweeney.
The 25-year-old, who made his Test debut in the series-opener in Perth, failed to score a single half century and could manage scores 10, 0, 39, 10 not out , 9 and 4 in his six innings and was dismissed by Indian pace Jasprit Bumrah spearhead four times.
Konstas had been in the reckoning to partner Usman Khawaja after grabbing the attention of Cricket Australia's selection committee following his twin Sheffield Shield centuries for New South Wales.
He had scored an unbeaten 73 at the MCG against India A while notching up a ton (107) in the Prime Ministers XI pink ball game against India in Canberra.
"Sam gets a call up to the Test squad for the first time. His style of batting offers a point of difference and we look forward to watching his game develop further," Australian Chair of Selectors George Bailey said.
"We remain confident Nathan has the ability and temperament to succeed at Test level in the future. It was a difficult decision to leave him out.
"It has clearly been a challenge at the top of the order for batters throughout the series and we want to provide the option of a different line up for the next two matches," he added.
If Konstas, who turned 19 on October 2, is selected in the playing XI in the Boxing Day Test, he would become Australia's youngest Test debutant since captain Pat Cummins, who was 18 years and 193 days old when he made his debut against South Africa in Johannesburg in 2011.
"It would be a dream come true (playing the Boxing Day Test)," Konstas had said earlier this week
"Maybe I'd get a little nervous before the game, but I've worked really hard for that. Hopefully, it happens one day, but we'll see," he added.
He would also become second-youngest player – and the youngest specialist batter – to debut for Australia since Ian Craig when he played against South Africa at the MCG in 1953 aged 17 years 239 days.
Pacer Jhye Richardson has also been included in the 15-member squad in place of Josh Hazlewood, who has been ruled out due to a cafe injury.
Richardson, who himself has overcome a series of injuries, has not featured in a Test match since his three appearances during the 2021-22 Ashes series.
"In the absence of Josh Hazlewood, Jhye provides further options in the fast bowling space. It has been pleasing to see his successful return throughout the early part of the domestic summer," Bailey said.
Speedster Sean Abbott is also back in the squad for the remaining alongside uncapped Tasmania all-rounder Beau Webster, who was added ahead of the second Test in Adelaide.
