Australia has had its first one-day international win away from home in more than a year, with a 21-run win over India.
While India won the five-match series after winning the first three encounters, Australia snapped an 11-game away losing streak in Thursday’s fourth ODI in Bangalore.
David Warner’s 124 in his 100th match helped his side set India 335 to win, a target which the hosts fell 21 runs short of after some classy bowling at the death from Australia.
“We have to keep thinking about how to get better overseas because at the moment that’s just not good enough,” said Saker, who is standing in for Darren Lehmann.
“For a team with the talent we’ve got we need to get better at playing away from home.”
Before the victory, their most recent win on the road was in September last year over minnows Ireland in South Africa.
India were on target until an outstanding piece of fielding from skipper Steve Smith gave Australia a crucial breakthrough at 1-135.
His save at backward point sparked confusion between Virat Kohli and Rohit Sharma, who ended up at the same end as his partner before being run out for 65 at the other end.
Kohli edged an attempted late cut off Nathan Coulter-Nile onto his stumps on 21.
Legspinner Adam Zampa went for 41 off his first five overs, but bounced back with the vital wicket of Hardik Pandya (41) who was caught on the boundary by Warner.
Australian pacemen Coulter-Nile, Kane Richardson and Pat Cummins were exceptional in the final overs with Kedar Jadhav (67) and Manish Pandey (33) departing and MS Dhoni (15) unable to rescue the chase.
Richardson took the wickets of Ajinkya Rahane for 53, as well as Jadhav and Dhoni, and finished with 3-58.
Earlier, a 231-run opening stand from Warner and Aaron Finch set a superb foundation after Steve Smith won the toss and chose to bat.
A mini-collapse stunted the momentum of the innings as Warner, Finch (94) and Smith (three) departed in the space of 14 balls with Australia losing 3-5.
Head never got going in his knock of 29 off 38 balls after being elevated ahead of Smith to bat at No. 3.
Peter Handscomb made a handy 43, while Marcus Stoinis chipped in with 15 from nine balls to round out Australia’s innings.
Kohli said the team had no regrets about resting the bulk of their front-line bowling attack with Bhuvneshwar Kumar, Jasprit Bumrah and Kuldeep Yadav.
“We won the series and you have to try the guys out at some stage,” Kohli said.
“You need to test your bench strength as well.”
