Beginning his career at his local club, Pont l'Evêque, Batum made his professional debut with Le Mans in 2006 before switching to the NBA in 2008 when he was drafted 25th overall by the Houston Rockets who then traded his rights to Portland. During the NBA lockout in 2011, he briefly returned to France to sign with Nancy before resuming his career with the Trailblazers before being traded to Charlotte in June 2015. He played on the French national teams that claimed the gold medal at the U16 (2004) and U18 (2006) European Championship, taking MVP honours at the latter. He made his senior debut in 2009 in a friendly with Austria and had made 96 appearances heading into 2015, including an All Star Five berth as France took silver at the 2014 FIBA World Cup. His late father Henry also played professional basketball but died on court from a heart attack during a game in 1991. He helped set up the Foundation Batum to assist pregnant women and women with children in Africa.
