#2 Ravindra Jadeja
Ravindra Jadeja is the front-runner to grab the spot of a third spinner in the Indian squad for the 2019 World Cup.
Jadeja also comes with the added advantage of his batting and in recent times, has improved this facet quite a lot. He has always been very accurate with the bowl and can definitely give the skipper a cushion of being the fifth bowling option. And if Kedar Jadhav is also fit, India might play both of them as they can both give the team 10 overs and also bring depth to the batting.
Jadeja also played a vital role during India's Champions Trophy triumph in 2013, which also took place in England and he is also in the ODI squad for the upcoming series against Australia. This shows that the selectors are keen on picking him in the squad for the World Cup next summer.
