Fourth Season, 2011
Two new teams from Pune and Kochi were added to the IPL for the fourth season. The addition of teams representing Pune and Kochi increased the number of franchises from 8 to 10. The BCCI originally considered extending the tournament format used in previous season to ten teams, which would increase the number of matches from 60 to 94. Instead, the round-robin stage of the tournament was replaced by a group stage with two groups of five, limiting the number of matches to 74. But this format was replaced by another one in which each team would play 5 other teams in a two-way round robin format and there would be 2 teams against whom they would play only at home and remaining 2 teams against which they would play only away matches. Thus each team plays 14 matches.Top four teams would qualify for the semi-finals.
