David Warner and Steve Smith impress on return to Australian grade cricket

Banned internationals Steve Smith and David Warner were in the runs on their returns to Australian grade cricket for the first time since the ball-tampering scandal.

The pair were both banned from playing international and domestic cricket for 12 months by Cricket Australia for their roles in the plan to tamper with the ball during the Cape Town Test against South Africa earlier this year.

Former Australia skipper Smith and vice-captain Warner were allowed to play in the New South Wales Cricket competition, which began on Saturday.

Smith hit 85 for Sutherland against Mosman while Warner scored a match-winning knock for Randwick-Petersham, who won by four wickets off the last ball while chasing 278 against St George.

Warner carried his bat, his hundred coming off 98 balls, in an innings featuring 13 fours and two sixes.

"He played really well and is very good in those type of situations," said former Test team-mate Josh Hazlewood, who played against Warner on Saturday.

"We probably beat anyone else today, except David Warner. It was a pretty special knock."
