Suspension for betting

In September 2016, Lestienne was suspended for seven months and fined $10,000 by the International Tennis Federation for betting on tennis matches. The Tennis Integrity Unit (TIU) in cooperation with French online gambling regulator ARJEL found that Lestienne had bet on 220 tennis matches from February 2012 to June 2015. None of these matches were his own. Half of the ban was suspended, and his fine would be cut in half if he assisted the TIU.
