Note: Super Over wins and losses have been counted as wins and losses.
They are the joint-most successful team in terms of winning the IPL, for which they are tied with Mumbai Indians (MI) with three titles. And here too, they are the most successful IPL team in terms of win percentage. Chennai Super Kings (CSK) have arguably been the best team in IPL despite the two-year suspension from the league (2016 and 2017) for their owner’s alleged involvement in the IPL 2013 spot-fixing case and stats like these justify that assertion. Winning more than 60 per cent of their matches proves that Super Kings have been the most consistent team in the Indian Premier League. That they have played 23 matches less than Mumbai shouldn’t be a bone of contention.
Coming to Mumbai, they, too, have been consistent. In 2008 and 2009, the first two seasons of the league, they managed only 12 wins in 28 matches. So, to have won 86 of their next 143 matches (a 60.13 win percentage) is a reflection of how consistent they have been over the last nine seasons. The recurring failure to defend titles has undermined their win percentage.
As you can see, Pune Warriors India (PWI) have the lowest win percentage of all IPL teams, though they played only three seasons from 2011 to 2013.
Of the teams who have played all 11 seasons of IPL, Delhi Daredevils (DD) have the lowest win percentage (41.61).
Royal Challengers Bangalore (RCB) are the franchise who have underachieved the most, in terms of their failure to win the IPL even once. A win percentage of only 47.30, with more defeats than wins, shows they have not been consistent. However, they have reached the final thrice (2009, 2011 and 2017) and thereby had chances to lift the trophy.
