Meet Will Bosisto, Australia's captain
When his side has needed him at the ICC Under-19 Cricket World Cup, Australia captain Will Bosisto has delivered.
The 18-year-old scored 189 runs in his five matches at the tournament, catching the eye with his dogged displays at the crease.
But it has been the high-pressure situations his runs have come in that have really impressed.
In his side's first match of the ICC Under-19 World Cup, Australia skittled England for just 143 but were shaking at 30-3 when Bosisto came to the crease.
He hit a composed 35 not out from 85 deliveries and after scoring an unbeaten seven in Australia's 212-win over Nepal, he again carried his side over the line in a tricky run-chase.
This time it came against Ireland, as his side once again stuttered in the top order before Bosisto came to the rescue with a 91-ball 36 that helped Australia reach their victory target of 130 with six wickets in hand.
Those performances were impressive but once they were out of the group stages ? where Australia were always likely to progress in the top two ? the skipper stood up most.
A tense knockout match against Bangladesh saw a place in the semi-finals up for grabs and the Aussies were set a tricky chase of 172.
Cameron Bancroft (one), Meyrick Buchanan (zero) and Kurtis Patterson (zero) all fell early as Bosisto strode to the crease at 11-3.
He was batting when perhaps the most controversial moment of the tournament occurred, when Jimmy Peirson was 'mankaded' by Bangladesh's Soumya Sarkar and sent on his way for 21.
Like the umpires, Bosisto pleaded with the Bangladesh players to withdraw their appeal ? the dismissal occurred when Peirson left his crease early at the non-strikers end and Soumya whipped the bails off immediately ? but he was unsuccessful.
At 33-4, it would not have been surprising to see Australia lose.
They found themselves on the wrong side of potentially a huge turning point and such collapses are common in Under-19 cricket.
But it would not happen while Bosisto was at the crease.
He made a superb 71 not out from 134 deliveries, hitting seven boundaries in a composed innings that highlighted his fighting qualities with the bat as the Aussies won with five wickets in hand and 25 balls to spare.
The West Australian entered his side's semi-final against South Africa without a batting average after being not out for the four previous matches at the tournament.
And with the score at 188-6 ? just four runs away from Australia's victory target ? Bosisto was unbeaten on 40.
His amazing run of not outs did end though, with a Theunis de Bruyn direct hit catching him short of his ground.
It was not surprising that his long-awaited dismissal would come from a run out. After all, no bowler could get him out.
Bosisto's qualities are not limited to his batting.
He is an excellent leader and is an involved captain, who speaks to his bowlers regularly about plans to dismiss batsmen. He is also a terrific speaker and an impressive young man.
In four of Australia's five matches at the tournament, Bosisto has led his country to victory in run-chases.
And you would not bet against him doing it again in Sunday's final.
