Kohli hits ton in India's debut day-night Test

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."

Mumbai, Mar 3: India on Tuesday retained their number one spot and captain Virat Kohli remained static at second in the ICC rankings despite a dismal Test series against New Zealand.

India have 116 rating points, six more than New Zealand with third-placed Australia accumulating 108 points. The 0-2 result against New Zealand was India's first series loss in the World Test Championship.

Kohli remains in second position in the batting rankings despite a forgettable Test series in which he made 38 runs in four innings, the ICC said in a statement.

New Zealand opener Tom Blundell and his Indian counterpart Prithvi Shaw and debutant paceman Kyle Jamieson were among the biggest movers in the rankings, released on Tuesday.

Blundell had a successful series against India, scoring 117 runs in four innings, with one half-century, which put him among the top two run-scorers in the series.

The performance meant he was rewarded with a jump of 27 places to No. 46. Shaw, who returned for his first series since his Test debut against West Indies in 2018, and made a punchy 54 in the first innings of the Christchurch Test, rose 17 places to No.76.

Australia's Steve Smith retained his top spot, holding a 25-point advantage over Kohli. Smith's apprentice Marnus Labuschagne jumped one spot to round off the top three, taking the place of New Zealand captain Kane Williamson.

England all-rounder Ben Stokes and India opener Mayank Agarwal moved a spot each and swapped places to break into and fall out of the top 10 respectively.

Among bowlers, Tim Southee's Player of the Series winning performance against India took him into the top five, with a jump of two places to No.4, while Jasprit Bumrah and Trent Boult returned to the top 10, gaining four places each to occupy the seventh and ninth positions respectively.

But the biggest gainer was Jamieson, who rose from No. 80 to 43.

There was only one change in the top ten among all-rounders, with Southee dropping a spot to No.10 and team-mate Neil Wagner falling out of the top 10 with a drop of four spots.

As with the bowling rankings, Jamieson, who frustrated India with handy lower order runs, gained big on the all-rounders' table, rising 26 places to No. 22.
