Australia relieved as captain Cummins finds form

Pre-match talk of Pat Cummins being sensationally dropped from Australia's World Cup lineup to face Sri Lanka was proved unfounded and also somewhat ludicrous after the pace-bowling skipper produced a crucial spell to help beat the South Asians.

Spinner Adam Zampa led the bowling with four wickets in Australia's five-wicket win on Monday but it was Cummins who unlocked the Sri Lankans after openers Pathum Nissanka and Kusal Perera put on a century stand.

Cummins banged in a short ball to remove Nissanka for 61, with David Warner assisting with a brilliant catch, before the captain bowled Perera for 78 with a fine delivery that extracted movement from a largely tepid pitch.

Cummins then produced an inspired piece of fielding to run out Dunith Wellalage for two as Sri Lanka were bowled out for 209 and easily picked off by the Australian batters.

With Cummins managing a total of one wicket from twin thrashings by India and South Africa, former Australia captain Michael Clarke caused a media storm back home when he told local radio that the skipper was set to be dropped against Sri Lanka.

The very idea of Cummins being on the chopping block was mystifying to legspinner Zampa, who was adamant there was no heat coming from within the team.

"I thought Cummins's spell in particular was a bit of a game changer for us and even his energy in the field, the run-out after the rain-break, yeah, it changed the energy for us," Zampa told reporters.

"We all back each other 100 per cent in this team, so I don't really know what's been said or what people are reading, but the only thing that I saw come on the WhatsApp group was same 11 as last game.

"So, yeah, there's no pressure on Pat there."

The win lifted Australia off the bottom of the World
