Jadeja, who leapfrogged Josh Hazlewood, James Anderson, Dale Steyn and Rangana Herath, has also gained a place to reach his career-best third rank in the list of all-rounders, which is also headed by Ashwin.
Meanwhile, India pace bowler Ishant Sharma has moved up two places to 23rd position.
In the Test Batsmen’s list, India’s KL Rahul and Karun Nair have also made huge gains. Rahul’s knock of 199 has helped him gain 29 slots to reach a career-best 51st spot, while Nair’s unbeaten 303 in only his third Test innings has lifted him 122 places to 55th position.
