Yasir Shah is the new name for leg spin in the world. Shane Warne declared him as the best leg spinner in the world at the moment so the debate over his new crown is a waste of time. The leggy picked up 15 wickets against England in the 2 games he played.
Yasir now has 76 test scalps in 12 test matches with an average of 24.17. These are the highest number of wickets by any bowler playing this much number of test matches in the last 100 years. There has been no way who got this many wickets in 12 matches.
He was awarded man of the series for his performance. Bob Willis commented on his performance that if Yasir would have been played the first test match as well it was 3-0 for England.
