The announcement came after former India pacer Ajit Agarkar, who guided the Mumbai team to their 40th Ranji Trophy title last season, announced his retirement.
"Rohit Sharma has been selected as captain of the Mumbai Team for the season 2013-2014," the MCA said in a statement issued here on Wednesday (October 16).

Rohit would be doing national duty against Australia in the ongoing ODI series at that time.
Sachin Tendulkar, who is retiring from Test cricket after playing his landmark 200th match here against the West Indies next month, has also been picked in the 15-member squad against Haryana.
