Aaron Finch’s hard work in the nets is starting to reap its rewards as a timely boost for Australia ahead of this summer’s World Cup.

Australia will be confident heading into Sunday’s second one-day international with Pakistan after a comfortable victory in the series opener on Friday.

Set 281 for victory, the Baggy Greens reached their target with one over to spare thanks to a superb century from skipper Aaron Finch and an unbeaten 91 by Shaun Marsh.

Peter Handscomb also chipped in with 30 not out while Shan Masood’s unbeaten 101 for Pakistan proved to be in vain.

The sides do it all again on Sunday, once again in Sharjah, and the Asians will hope to hit back with the World Cup now looming large on the horizon (Pakistan 9/1 World Cup Outright).

However it will be tough, with Finch looking in ominously good form, something Marsh feels is down to his dedication in practice.

“He was brilliant tonight. He led from the front,” he said. “I know how hard he’s been working in the nets and to see him get the rewards was fantastic.”

The Aussies are third favourites for the World Cup at 5/1, with 15/8 England heading the market and India next at 3/1.

Finch is a perfectionist when it comes to his batting and, despite his brilliance, was seen ranting in the changing room after getting out.

“It was a really important time when we could have put the game to bed. I was disappointed,” he said when quizzed on his post-innings demeanour.

The 32-year-old Victorian will lead the Baggy Greens into this summer’s World Cup and, with Steve Smith and David Warner back in the ranks, the defending champions will be tough to beat.

Odds subject to change.
