Sania-Tecau in finals of mixed doubles

Jul 2: Cricket Australia has decided to not use the Dukes ball from this summer's Sheffield Shield, having used it alongside Kookaburra for four seasons.

CA has confirmed that the Kookaburra ball will be used for the entire 2020-21 first-class season.

Australia has been using Dukes ball since the 2016-17 season in Shield matches with an aim to help its cricketers prepare for the hostile English conditions.

CA's Head of Cricket Operations, Peter Roach, said the decision to axe the Dukes was the right call. "The introduction of the Dukes ball has been a worthwhile exercise, particularly in the lead up to overseas Ashes series where the Dukes is used so well by our English opponents," Roach said.

"We have been happy with how the ball has performed when used in Australian conditions over the past four seasons. We do, however, feel that reverting to one ball for 2020-21 will provide the consistent examination of our players over a full season that CA and the states are presently seeking. The Kookaburra is the ball used for international cricket in Australia and many parts of the world and we see benefits this season of maximising our use of it," he added.

Roach said the ineffectiveness of spinners in first-class cricket in recent times played a role in CA's decision to do away with the Dukes. "We have noted that spin bowlers in the Sheffield Shield have been playing less of a role in recent seasons, most notably in games when the Dukes ball is in use. We need spinners bowling in first-class cricket and we need our batters facing spin. We hope that the change to one ball will have a positive benefit here," he said.

The CA official, however, didn't rule out the possibility of re-introducing it later.

"We see a definite opportunity to reintroduce the Dukes ball at some stage in the future."

Sydney, Jan 6: Nathan Lyon captured five for 50 and 10 match wickets as Australia crushed New Zealand by 279 runs on Monday, capping a golden domestic summer as they swept the three-Test series.

The off-spinner led the powerful Australian bowling attack to dismiss the Kiwis for 136 and seal another heavy win over the Black Caps after similar victories in Perth and Melbourne.

Australia have been unbeatable this season, winning all five Tests at home -- two against Pakistan and three against New Zealand -- after retaining the Ashes by drawing the series 2-2 in England.

"It's been a great summer for the Australian Test side," Lyon said.

"It's pretty special to be part of it, we have been impressive, pretty clinical, the batters have done well and given us bowlers plenty of time."

Australia declared their second innings at 217 for two with David Warner scoring an unbeaten century, leaving the Black Caps with a revised 416-run target in the fourth innings on a wearing Sydney Cricket Ground pitch.

But the Kiwis buckled under the pressure of Australia's superior bowling attack with Mitchell Starc taking three for 25 to support the wiles of spinner Lyon.

"They were clinical in all areas and after the first match they put us under pressure session after session," said skipper Kane Williamson, who missed the Test with a virus.

New Zealand were reeling early at 27-4 and never recovered after Starc and Lyon took two wickets each in the middle session to put the skids under the tourists.

Starc removed both openers, Tom Latham and Tom Blundell, in the first five overs. Blundell fell to a stunning catch by a diving Lyon at point for two and stand-in skipper Latham lost a review for leg before wicket.

Jeet Raval was out in a review to the faintest of edges on 'Snicko' in Lyon's first over for 12.

First-innings top-scorer Glenn Phillips went for a duck after technology detected a faint outside edge to wicketkeeper Paine off Lyon.

Taylor's Kiwi record

Ross Taylor became the leading all-time Kiwi batsman, going past Stephen Fleming (7,172) before he was bowled by Pat Cummins for 22 to take his Test aggregate to 7,174.

Big-hitting Colin de Grandhomme smacked Lyon for six to bring up his fifty but went next ball hoicking to Joe Burns at deep mid-wicket for 52.

Todd Astle was out to a superb diving catch by James Pattinson in the outfield for 17.

Starc yorked William Somerville's middle stump for seven and BJ Watling was the last to fall, caught at backward square leg by Pat Cummins for 19.

Earlier, Warner completed his 24th Test century and remained unbeaten when skipper Paine declared upon the dismissal of Marnus Labuschagne.

"You know you're capable of doing so," Warner said, when asked about how he had bounced back from his disastrous Ashes campaign in England last year.

"I was in the nets hitting the ball well and had the skipper backing me. To be able to play with freedom helped me. It's all paying off."

Labuschagne, who was dropped on four in a regulation caught-and-bowled chance by leg-spinner Astle, was caught at long on off Matt Henry for 59 -- his seventh score over 50 in eight innings this domestic summer.

Labuschagne finished the home five-Test season with a stunning aggregate of 896 runs, made up of his 215 in the first innings, three other centuries and three half-centuries in eight innings.

There was drama late in the Australian innings when Warner was given an official warning by umpire Aleem Dar for running down the middle of the pitch in scampering a single.

It resulted in five penalty runs being added to New Zealand's first innings total meaning their target was revised down from 421 to 416.

The Test was played against the backdrop of one of Australia's most devastating bushfire seasons with at least 24 people losing their lives in blazes raging across the country, including on the outskirts of Sydney.

New Delhi, Jan 16: Veteran cricketer Mithali Raj was on Thursday demoted to Grade B from A in the BCCI central contracts while Radha Yadav and Taniya Bhatia were elevated to the middle bracket.
