MELBOURNE: Shane Watson notched up his second half century as Australia extended their lead to 307 on the third day of the first Test against Pakistan here today.

The opener fended off a fiery opening spell from Mohammad Aamer (2-43) to end the day on 64 not out and guide Australia to 111-3 at close. Earlier, left-armers Doug Bollinger and Mitchell Johnson each took three wickets to dismiss Pakistan for 258. Umar Akmal (51) and Misbah-ul-Haq (65) provided the sole resistance.

With the impetus back in Australia’s favour after Umer’s dismissal, Bollinger ripped through Pakistan’s tail with three wickets in four overs. Misbah brought up his half century as Pakistan just moved beyond the follow-on target before Johnson (3-36) bowled Saeed Ajmal to end the innings.

Seamer Mohammad Asif gave the tourists the perfect start when he removed Simon Katich caught behind for two.

Ponting survived an LBW referral before he pulled a short delivery from left-arm seamer Aamer into the hands of Salman Butt at the deep square leg boundary. And the 17-year-old collected his second wicket when he trapped Mike Hussey (three) leg before wicket to leave Australia precariously placed at 40-3.

But alongside Michael Clarke (21 not out), Watson played with circumspect and aggression to ensure Australia maintain their dominance.
