"Can't catch. Can't field."

Pace legend Waqar Younis has slammed Pakistan's fielding in the third Test against Australia in Sydney.

The tourists face the genuine prospect of a 3-0 series whitewash after the hosts cantered to a mammoth 4-454 at lunch on day two at the SCG.

Veteran paceman Wahab Riaz put the onus on the bowling unit after day one, however Waqar said the attack wasn't solely to blame for a sorry start to the match.


At least three chances went begging in the first session on Wednesday, including Younis Khan handing debutant Hilton Cartwright a lifeline by dropping a regulation catch off hard-working spinner Yasir Shah's bowling.

"That was the easiest of the lot. Can't catch, can't field," bemoaned Waqar in commentary for the Nine Network.

"(The bowlers) get demoralised. It's very difficult to pick yourself up to bowl again. It's a tough wicket to bowl on and you create an opportunity or a chance, then someone put it down."

Yasir should've had Cartwright stumped earlier in the day, while poor fielding continued to cruel any chance of the visitors playing themselves back into the contest.

Captain Misbah-ul-Haq wasn't immune to their problems in the outfield, almost pegging a ball into a teammate in the third over of the day.

Australian great Shane Warne empathised with Yasir.

"This is just disheartening for the bowler. Yasir Shah's gone for 140 again and 40 of them could've been stopped. You've got to feel for the Pakistan bowlers, you can't miss that," he said.
