The teenage duo of Jack Edwards and Jason Sangha both brought up their maiden Sheffield Shield centuries for the NSW Blues on a momentous day at the SCG on Tuesday.

Sangha, 19, was dismissed for 117 on the second day of the match against Tasmania, while Edwards (101) became the fourth youngest player to score a First Class century for New South Wales at 18 years and 201 days. The Blues declared at 9/442 during the second session and, in reply, Tasmania are 3/108 at stumps.

Blacktown-born Jake Doran (6 not out) and Tasmanian captain George Bailey (1 not out) were unbeaten at the close of play. Blues seamer Trent Copeland (3-22) claimed three late wickets for the home side.

Edwards and Sangha shared an immense 180-run partnership for the sixth wicket and showed maturity beyond their years to rescue the Blues from the precarious position of 5/181 late on day one.

It was the third occasion in the history of Sheffield Shield cricket that two teenagers had scored a century in the same Sheffield Shield match and the pair joined illustrious company.

Former Australian captain Ricky Ponting and Michael Di Venuto both made centuries in the same fixture before their 20th birthdays in 1993. Queensland pair Martin Love and Jimmy Maher did likewise as teenagers in 1994.

Love played five Tests for Australia in 2002/03. Di Venuto and Maher both played One-Day Internationals for their country.

Sangha struck 10 boundaries and one six during his 223 balls at the crease. It was his second First Class century after he made 133 against the touring England side last summer.

In the process, he became the second youngest batsman to ever score a century against the English behind Indian master batsman Sachin Tendulkar.

Edwards spent 149 deliveries in the middle during his knock. He also reached the boundary 10 times and cleared it twice.

Both young men were team mates for Australia at the Under 19 World Cup in New Zealand earlier this year in a squad captained by Sangha.

Their magnificent partnership was broken when an attempted hook shot by Edwards found Alex Doolan in the deep to give Riley Meredith (2-64) his second scalp.

Sangha was the next wicket to fall when he spooned a catch to point from the part-time medium pace of Matt Wade (1-31).

Steve O’Keefe (31) and Trent Copeland (27 not out) both played some free-flowing strokes and added some handy runs before the declaration was made.

Tasmanian seamer Gabe Bell (3-75) claimed best figures for the visitors.

It was tough going for the Blues bowlers across the final two sessions of play until Copeland weaved his magic.

Doolan (53) and Jordan Silk (39) shared an opening partnership of 92 and looked at ease before Copeland finally struck.

He claimed the vital scalps of Doolan for 53 in the 38th over. The opener was dropped by Edwards from the bowling of Nathan Lyon early on his innings, but the teenager redeemed himself by taking the catch that eventually removed Doolan.

Copeland soon had two wickets, when on the second last ball of the same over, he claimed Silk caught behind. The wily Blues seamer then had three when Webster fell in similar fashion for eight and all of sudden the visitors had lost 3/8.
