The rise of left-arm spinners is a significant shift in international cricket from the 20th to the 21st century. In just 23 years of this century, left-arm spinners have exceeded the total wickets taken by their predecessors from the entire 20th century. Previously, 194 left-arm spinners took over 6,000 international wickets with a strike rate of 77.2. Since 2000, their numbers have doubled to 408, who have now taken over 13,600 wickets with a greatly improved strike rate of 43.5.
