Mahendra Singh Dhoni, sometimes abbreviated as MS Dhoni (Hindi: महेन्द्र सिंह धोनी) (born 7 July 1981 in Ranchi, Bihar) (now in Jharkhand) is an Indian cricketer and the current captain of the Indian team. Initially recognized as an extravagantly flamboyant and destructive batsman, Dhoni has come to be regarded as one of the coolest heads to captain the Indian ODI side. Under his captaincy, India won the 2007 ICC World Twenty20, CB Series of 2007-08 and the Border-Gavaskar trophy 2008 in which they beat Australia 2-0. He also lead the team to their first ever bilateral ODI series wins in Sri Lanka and New Zealand. 
Dhoni has also been the recipient of many awards including the ICC ODI Player of the Year award in 2008 and 2009 (the first Indian player to achieve this feat), the Rajiv Gandhi Khel Ratna award and the Padma Shri, India's fourth highest civilian honour in 2009. As of November 2009, Dhoni is the highest ranked ODI batsman on the ICC Rankings List. Also Dhoni was named as captain of Wisden's first-ever Dream Test XI Team in 2009. Mahendra Singh Dhoni has topped the list of world’s top 10 earning cricketers compiled by Forbes. 
Personal life:Mahendra Singh Dhoni was born in Ranchi, Bihar (now in Jharkhand) to Pan Singh and Devaki Devi. His paternal village Lvali is in the Lamgarha block of the Almora District of Uttarakhand. Dhoni's parents, moved from Uttarakhand to Ranchi where Pan Singh worked in junior management positions in MECON. Dhoni has a sister Jayanti and a brother Narendra. Dhoni had long hair which he has now shortened; he cut it because he wanted to look like his favourite film star John Abraham. Dhoni is a fan of superstar Rajnikanth, Adam Gilchrist, and his childhood idols were cricket teammate Sachin Tendulkar, Bollywood actor Amitabh Bachchan and singer Lata Mangeshkar.
Dhoni studied at DAV Jawahar Vidya Mandir, Shyamali,(now the school is known as JVM , Shyamli,Ranchi) Ranchi,Jharkahnd where he initially excelled in badminton and football and was selected at district and club level in these sports. Dhoni was a goalkeeper for his football team and was sent to play cricket for a local cricket club by his football coach. Though he had not played cricket, Dhoni impressed with his wicket-keeping skills and became the regular wicketkeeper at the Commando cricket club (1995 - 1998). Based on his performance at club cricket, he was picked for the 1997/98 season Vinoo Mankad Trophy Under-16 Championship and he performed well. Dhoni focused on cricket after his 10th standard. 
Playing style:Dhoni is a right-handed batsman and wicket-keeper. Dhoni is one of the number of wicket-keepers who have come through the ranks of junior and India A cricket teams to represent the national team — Parthiv Patel, Ajay Ratra and Dinesh Karthik also followed this route. Dhoni, referred to as 'Mahi' by his friends, debuted in the Bihar cricket team during the 1998/99 cricket season and was selected to represent India-A for a tour to Kenya in 2004. Along with Gautam Gambhir, Dhoni made multiple centuries against the Pakistan-A team in a tri-nation series and was selected in the Indian national team later in that year.
Dhoni tends to play mostly from the back foot with a pronounced bottom hand grip. He has a very fast hand speed through the ball which often results in the ball racing across the ground. From this initial stance his feet do not show much movement which sometimes results in chasing balls while not coming to the pitch of the ball or inside edging a lot of balls.
Dhoni scored 148 against Pakistan in his fifth ODI match in 2005 — then the highest score by an Indian wicketkeeper. Later in the year, he broke his own record as well as set the current world record for the highest score in the second innings in ODI matches as he scored 183* against Sri Lanka. Dhoni's success in the limited overs format secured him a place in the test team. Consistent performances in ODI cricket through the end of the 2005/06 season saw Dhoni briefly ranked as the No. 1 batsman in the ICC ODI ratings. 
Dhoni's form dipped through 2006 as India lost matches at the ICC Champions trophy, DLF Cup, away bilateral series against West Indies and South Africa. A return to form in the home series against West Indies and Sri Lanka in early 2007 proved to be an inaccurate indicator of Dhoni's form as India crashed out of the first round in the 2007 Cricket World Cup. Dhoni was out for a duck in both India's losses. After the World Cup, Dhoni won the Man of the series award in the bilateral ODI tournament against Bangladesh. For the tour of England, Dhoni was named the ODI team vice-captain. 
As a batsman, Dhoni has shown the maturity to restrain his aggressive nature and play a responsible innings when the situation requires. Apart from traditional shots, Dhoni has two very unorthodox but effective cricket strokes. Since his entry into the Indian cricket team, Dhoni's aggressive batting style, success on the field, personality, and long hair have made him one of the most marketable cricketers in India.
