Mumbai Indians retain Rohit Sharma, Lasith Malinga and Harbhajan Singh

Defending champions Mumbai Indians Friday decided to retain skipper Rohit Sharma, Harbhajan Singh and Ambati Rayudu, Sri Lankan fast bowler Lasith Malinga and West Indies all-rounder Kieron Pollard in accordace with the Indian Premier League (IPL)'s new retention rules for the season 2014.

Mumbai Indians surprisingly have decided to let go Australia's Ashes hero Mitchell Johnson, who picked up 37 wickets during the Test series against England. The franchise, however, could get back the fast bowler with the right-to-match option during next month's players auction.

"The formidable combination of these five players - Rohit, Pollard, Malinga, Bhajji and Rayudu - forms the nucleus of Mumbai Indians. They have exemplified the spirit of Mumbai Indians and are match-winners in their own right," said team owner Nita Ambani.

Nita Ambani said the five retained players will form the core of the team.

"With the retention of the core players, Mumbai Indians look forward to build a stronger, well-knit team and share the joy of an enthralling and entertaining performance with its ever-growing fans in the coming season," she added.
