India captain Virat Kohli has won the toss and elected to bat against Australia in the fourth ODI in Mohali.
The hosts, who lead 2-1, have made as many as four changes.
Rishabh Pant comes in for Mahendra Singh Dhoni, who has been rested for the last two games, while KL Rahul replaces the struggling Ambati Rayudu.
Mohammed Shami also misses out with injury as he makes way for Bhuvneshwar Kumar and leg-spinner Yuzvendra Chahal comes in for Ravindra Jadeja.
Welcome to the coverage of the fourth One-Day International between India and Australia in Mohali on Sunday.
India will be aiming to resurrect their middle order woes and bounce back to winning ways, which will help them clinch the five-match series.
Providing opportunities to all Cup hopefuls would be on Virat Kohli’s mind and the team management is expected to ring in a few changes in the playing XI in the remaining two matches of the series.
Bhuvneshwar Kumar also makes a comeback as he replaces Mohammed Shami, who was hit on the leg in his follow through during the third match.
However, what will keep the Indian team worried is the batting form of the top-order — save skipper Kohli.
Kohli has 283 runs in three games with two hundreds in the series so far and the next best in the Indian team is Kedar Jadhav with 118 runs.
Rohit Sharma is undergoing a rare slump in ODIs, having scored only 51 runs in three innings. Even worse is Ambati Rayudu’s performance at No 4 with an aggregate of 33 runs in three games.
Shikhar Dhawan’s struggles are well-documented and he has scored only 22 runs in three games.
Dhawan and Rayudu’s form should be a cause of concern even though both are certainties as far as their place in the World Cup squad is concerned.
