Bowler Naseem managed, not injured: Waqar

Pakistan restricted their use of 16-year-old Naseem Shah on day three against Australia

As Australia's batsmen did as they pleased at the Gabba, teen sensation Naseem Shah mostly stood in the field and watched.

The 16-year-old bowled just four overs on Saturday - he sent down 16 on Friday - but still managed to rough up David Warner and collect the opener as his first Test scalp.

He was unsighted beyond that though as Marnus Labuschagne motored to 185 and the hosts racked up 580.

Pakistan will resume on day four at 3-64, still 276 runs adrift ahead of Adelaide's second and final Test starting Friday.

Captain Azhar Ali said pre-game he had confidence Naseem would be able to handle the physicality of a Test.

Following play on Saturday bowling coach Waqar Younis denied Naseem was injured and that his conspicuous lack of overs on day three was due to management.

"We have to be very careful with Naseem Shah," he said.

"He's very, very young and we have to manage him well because he bowls very quick.

"You don't want to put too much load on him, be careful with him.

"He is the future for Pakistan. We have to use him sensibly and I thought that's what the captain did.

"He's a wicket-taker. It was just his first Test match."

Waqar defended the decision to leave out proven Test performer Mohammad Abbas, who averages a Pakistan-best 18.86 after 14 Tests.

But he said his youthful attack, which also features 19-year-old Shaheen Shah Afridi, had learnt the hard way where not to bowl in Australian conditions.

"We sit down every evening and we talk about it and try to teach them what lengths need to be bowled. I think we missed it.

"It was very obvious and everyone has seen that our lengths weren't right.

"With the first new ball we bowled poorly. If we would have put the ball in the right areas, things might have been different.

"We got carried away and with a young attack it can happen in Australia."
