Australia miss review as Pakistan pass 300

Australia have been left with DRS regret as Pakistan made use of a missed chance to hammer home their advantage at 1-302 on day two of the first Test in Rawalpindi.

On a tough morning for bowlers, Azhar Ali closed in on his third century in five Tests against Australia in Asia as he went to the break unbeaten on 95.

Imam-ul-Haq remains not out on 154, having batted through the first 115 overs of the innings for his maiden Test century.

Australia have gone to lunch knowing they had the chance to remove the opener but didn't take it.

Wearing two black armbands to commemorate the deaths of Shane Warne and Rod Marsh, Nathan Lyon outsmarted Imam-ul-Haq on 143 when the left-hander went back to cut.

There were two sounds and Australia immediately went up, before wicketkeeper Alex Carey immediately played down any chance of a review when Iman was given not out on field.

Replays immediately showed a spike on ultra edge, meaning the on-field call would likely have been overturned had Australia requested a review.

The ball was a rare moment of excitement for Australia on what has otherwise been a flat morning on a docile wicket.

Pakistan scored at just 2.28 runs per over, with very little on offer for the bowlers and only some turn for Lyon.

Captain Pat Cummins offered up the only other real moment of life with a ball that climbed quickly and struck Azhar's gloves early, with other short balls generally sitting up.

Australia's best hope is likely if the ball begins to reverse swing, with some hint of that for Mitchell Starc late in the session.

Cummins entered day two knowing they had to strike a balance between containing runs and taking wickets.

The tourists do not want the match to get away but know if Pakistan are still batting
