Five days of fascinating Karachi contest ends with a draw on Wednesday with Pakistan skipper Babar Azam playing an epic knock against Australia. Pakistan managed just 148 runs in reply to Australia's 556/6d in the first innings, which featured Islamabad-born Usman Khawaja's emotional ton. But the hosts, chasing an improbable target of 506 runs, scored 443/7 in the fourth innings at National Stadium. Australia declared their second innings at 97/2d early on Day 4, and they were in control after taking two early wickets. But Azam and young opener Abdullah Shafique dropped anchor to stitch a 228-run stand in 524 balls to keep Pakistan's hopes alive. Shafique missed a ton by four runs, but vice-captain Mohammad Rizwan completed his and fended off the Aussies in a tense finish. Nauman Ali played the perfect supporting role to Rizwan. Nathan Lyon, who toiled so hard, claimed two wickets in two towards the end on Day 5 to end with figures of 4/112. For the record, Azam's 196 in the highest fourth innings score by a captain. The third and final Test at Gaddafi Stadium, Lahore starts March 21. Catch Day 5 highlights and cricket scores of the second PAK vs PAK Test match:

Day 5 Preview

More than two years after he scored his last hundred, Babar Azam timed his century perfectly. The Pakistan skipper showed his class and temperament on?Tuesday?as Pakistan battled Australian bowlers on a hot day in Karachi.

Till?Monday, it was all about Australia. Day 4 was won by the Pakistanis as Babar Azam (unbeaten on 102) and Abdullah Shafique (batting on 71) stitched a valuable 171-run partnership for the third wicket to keep the hosts afloat and Australians frustrated.

Pakistan still need an improbable 314 runs to achieve a world record run chase on the last day or survive the remaining 90 overs to deny Australia taking a 1-0 lead in the three-match series. Pakistan’s highest successful chase in Test matches is 382 for 3 in 2015 when they beat Sri Lanka by seven wickets at Pallekele.

Australia still have the advantage in this Test. Batting will be a challenge on Day 5. Australia will come out charging with the second new ball. Spin and reverse swing, seen in plenty in this PAK vs AUS game, will also come into play. The first Test in Rawalpindi ended in a draw.
