The 2011 Indian Premier League season, abbreviated as IPL 4 or the IPL 2011, was the fourth season of the Indian Premier League, the top Twenty20 cricket league in India. The tournament was hosted in India and the opening and closing ceremonies were held in M. A. Chidambaram Stadium, Chennai, the home venue of the reigning champions Chennai Super Kings. The season ran from 8 April to 28 May 2011. This season the number of teams in the league went from eight to ten with the additions of the Pune Warriors India and the Kochi Tuskers Kerala.
The tournament was won by the Chennai Super Kings for the second successive season, defeating Royal Challengers Bangalore by 58 runs in the final in Chennai, with the winning team's Murali Vijay being named Man of the Match. With this win Chennai Super Kings became the only team to have won the IPL on more than one occasion. Despite Bangalore failing to win the title, one of the team's players, Chris Gayle was named as the tournament's best player. He scored 608 runs in twelve innings – the most in the tournament – as well as picking up eight wickets, having joined the team after the start of the season due to an injury to another overseas player, Dirk Nannes. Mumbai Indians' Lasith Malinga set a new record for most wickets taken within an Indian Premier League season, claiming 28 wickets during the campaign, but Mumbai had to settle for third place in the tournament, having lost to Bangalore in the second qualifier. Chennai, Bangalore and Mumbai represented India in the Champions League 2011 tournament in September. The Fly Kingfisher Fair Play Award was again won by the Chennai Super Kings for topping the fair-play table.
Harbhajan Singh Plaha (born 3 July 1980 in Jalandhar, Punjab, India), commonly known as Harbhajan Singh, is an Indian cricketer. A specialist bowler, he has the second-highest number of Test wickets by an off spinner, behind Sri Lanka's Muttiah Muralitharan.
Harbhajan made his Test and One Day International (ODI) debuts in early 1998. His career was initially affected by investigations into the legality of his bowling action, as well as several disciplinary incidents. However in 2001, with leading leg spinner Anil Kumble injured, Harbhajan's career was resuscitated after Indian captain Sourav Ganguly called for his inclusion in the Border-Gavaskar Trophy team. In that series victory over Australia, Harbhajan established himself as the team's leading spinner by taking 32 wickets, becoming the first Indian bowler to take a hat trick in Test cricket.
