Marnus Labuschagne notched a gritty score of 44 not out to guide Australia through a rain-interrupted first day of play in the second test against Pakistan at the Melbourne Cricket Ground on Tuesday. Invited to bat first by Pakistan captain Shan Masood, who won the toss in overcast conditions, Australia reached 187-3 at stumps. Pakistan squandered a golden opportunity to put Australia on the back foot early, allowing openers David Warner (38 off 83 balls) and Usman Khawaja (42 off 101) to share a 90-run partnership on a pitch offering sideways movement for the seamers. Warner, in his penultimate test, played a loose shot outside off stump on 38 in the final over before lunch and was caught at slip off the bowling of spinner Agha Salman. The 37-year-old Warner, who scored 164 in the first test in Perth, was lucky to reach double figures Tuesday. Warner offered a regulation chance on 2 to first slip off the bowling of Shaheen Shah Afridi in the third over, but it was put down by Abdullah Shafique.
