Yuvraj Singh (born 12 December 1981) is a former Indian cricketer, who played in all forms of the game. An all-rounder who bats left-handed in the middle order and bowls slow left-arm orthodox, Yuvraj is the son of former Indian fast bowler and Punjabi actor Yograj Singh. Yuvraj was a member of the Indian cricket team in One Day Internationals (ODIs) between 2000 and 2017 and played his first Test match in October 2003. He was the vice-captain of the Indian ODI team between 2007–2008.
He was the Man of the Tournament in the 2011 ICC Cricket World Cup. He was one of the top performers at the 2007 ICC World Twenty20, both of which India won. In a match against England at the 2007 World Twenty20, he famously hit six sixes in one over bowled by Stuart Broad. A feat performed only three times previously in any form of senior cricket, and never in an international match between two Test cricket teams. In the same match, he set the record for the fastest fifty in Twenty20 Internationals and in all Twenty20 cricket. He reached 50 runs in 12 balls. During the 2011 World Cup, he became the first player to take a 5-wicket haul and score a 50 in the same World Cup match.
In 2011, Yuvraj was diagnosed with a cancerous tumor in his left lung and underwent chemotherapy treatment in Boston and Indianapolis. In March 2012, he was discharged from the hospital after completing the third and final cycle of chemotherapy and returned to India in April. He made his international comeback in a Twenty20 match in September against New Zealand shortly before the 2012 World Twenty20.
