Supremely talented NSW teenagers Jack Edwards and Jason Sangha have achieved a rare feat in their side’s JLT Sheffield Shield clash against Tasmania today.

The pair underlined their immense ability by both reaching three figures during the first session of day two at the SCG.

It is thought to be just the third time in Shield history two teenagers have scored centuries in the same match and the first time in almost 25 years.

The duo combined for a 180-run stand for the sixth wicket, with 18-year-old Edwards dismissed for 101 shortly before lunch, while 19-year-old Sangha made 117 before falling in the second session.

In November 1993, Michael Di Venuto (125) and Ricky Ponting (105) both scored tons for Tasmania against Western Australia, while in January 1994 Jimmy Maher (122) and Martin Love (119) hit centuries for Queensland against WA.

The four were all aged 19 at the time and all went on to represent Australia.

After NSW experienced a collapse of 4-44 on Monday, Edwards and Sangha helped the home side reach 5-285 at stumps.

Edwards resumed on 50 before racing to 101 from 149 balls – an innings which included 10 fours and two sixes – with an errant hook shot resulting in his dismissal.

Sangha had 10 fours and a six to his name when he was removed and displayed a cool head against a Tasmanian attack featuring Test bowler Jackson Bird and the emerging Gabe Bell.

Edwards and Sangha were members of Australia’s under-19 World Cup team which went down to India in this year’s final.

"Jackson Bird was quite tough when I first came out, swinging it both ways," Sangha said after day one.

"They all bowled well.

"It was good fun but we've got a lot more hard work to do. This is just a start."

NSW handed full-contracts to five rookies – Param Uppal, Jason Sangha, Dan Fallins, Mickey Edwards and Liam Hatcher – at the end of last summer as they looked to build for the future.
