Australia hopeful Sam Konstas became the youngest man to score a half-century in the Big Bash League as Sydney Thunder beat Adelaide Strikers by two wickets.

Konstas, who is 19 years and 76 days old, overtakes Jason Sangha, who held the record at 19 years and 104 days.

Konstas, who was making his debut in the competition, also set the record of Thunder’s fastest half-century at 20 balls.

The New South Wales batter, who was out for 56 off 27 balls, was in consideration for Australia’s Test squad against India, but they opted for Nathan McSweeney instead.

Chasing 183, Thunder were 149-7 and needed 34 from the final two overs, but Daniel Sams smashed Lloyd Pope’s penultimate over for 31, including three sixes and three fours.

Jamie Overton, who earlier made an unbeaten 45 in Strikers’ 182-8, took a wicket with the first ball of the final over but Thunder scrambled over the line with two balls to spare.
