Australia skipper Pat Cummins won the toss and chose to bowl in the first of a three-match one-day series against Pakistan in Melbourne on Monday. With Mitchell Marsh and Travis Head on paternity leave, world champions Australia have a new-look opening partnership in Jake Fraser-McGurk and Matt Short.
Veteran Josh Hazlewood was rested with Sean Abbott joining Cummins and Mitchell Starc in the hosts' pace attack on an overcast day.

Pakistan's Test coach Jason Gillespie, the Australian former international, is in charge of the visitors for the series and three subsequent T20s.
