South Africa vs India 2018: 3 key battles that can decide the outcome of the ODI series 

#3 Bhuvneshwar Kumar vs Hashim Amla

Amla has struggled against Bhuvi's in-swinging deliveries in the recent past

After being mysteriously dropped from the side for the second Test match, Bhuvneshwar Kumar made a splendid comeback in the third Test and won the Man-of-the-Match award for his all-round show. While he had to fight for his position in the Test side, he will garner an automatic entry in the ODI series as he is the leader of the bowling attack. He has been excellent for India against top-quality sides, like England and Australia, and will want to carry on the good form against the Proteas as well. But Bhuvi will have his work cut out, as he will have to bowl against South Africa's most dependable batsman, Hashim Amla.

Amla opens the batting for South Africa in one-day cricket and has been highly successful. With Quinton de Kock going through a lean patch and AB de Villiers pulling out of the first three ODIs due to an injury, Amla will have to shoulder the responsibility of putting up a good score for the side. If Bhuvi is able to take Amla's wicket early on in the innings, India can attack South Africa's fragile middle order and restrict them to a low total.
