In modern day ODI cricket, where the pitches are in favour of batsmen, leg spinners play an important role to pick wickets and restrict the run flow of opposition.
Since the 2015 World Cup, the conditions in England have completely changed. The seamers have gone for plenty of runs. In the past 2 to 3 years, leg spinners have played key roles in the middle overs to stop the run flow as the batting sides have been posting 300 plus total and chased easily.
Every cricketing nation taking part in the tournament have top quality wrist spinners that can create an impact on the match.
