Bumrah is taken as the fifth seamer because among other pacers, Bumrah is the only guy who is ahead of the line waiting for a test call up. However I do not see Bumrah picked ahead of even Ishant Sharma. Bhuvi, Shami and Yadav should take the first 3 slots, followed by Ishant and then Bumrah.
Good to hear that India are sending 4 quality pacers from our domestic scene to bowl to our batsmen in the nets in South Africa.

Shows how serious we are this time of a good performance. Siraj, Thampi, Avesh Khan, etc. And usually we are hampered by poor net bowlers whenever we tour abroad. And also not wanting to exert our frontline seamers who have been picked in the test squad. This is a very good decision.
