Australia will be hoping that David Warner's debut as captain in Sunday's one-day international will be the circuit-breaker needed to rescue a disastrous tour of Sri Lanka.
The teams will take the field in Dambulla with the five-match series tied at 1-1, but with the weight of momentum leaning heavily in Sri Lanka's favour.
The home team embarrassed Australia with a 3-0 Test series clean sweep, and added insult to injury with a record 82-run win in Colombo to level the ODI series on Sunday.
Then came the surprise announcement that captain Steve Smith would return home mid-series "to make sure he's fresh", for the upcoming ODI tour of South Africa and home summer.
Warner's output with the bat will come under scrutiny after he was dismissed for 8 and 1 in the opening ODI's, and averaged just 27 in the Test series.

There is hope for the visitors, however, with the Dambulla wicket historically less favourable to spin.
Australia's frustration has been evident at times during the tour and fast bowler Mitchell Starc was reprimanded on Friday for a code-of-conduct violation after a run-in with batsman Dinesh Chandimal.
Sri Lanka paceman Thisara Perera was fined 15 per cent of his match fee for an over-enthusiastic send-off to Warner.
The third match will mark the final ODI for veteran Sri Lanka all-rounder Tillakaratne Dilshan.
