France won the Davis Cup for the first time in 16 years after beating Belgium 3-2. The Davis Cup is set to be transformed into a one-week, 18-nation World Cup of Tennis in a major overhaul of the international team event in mens tennis. The International Tennis Federation says it has unanimously endorsed a proposal to create a new season-ending event in November starting in 2019. The World Cup of Tennis would be played over seven days in the traditional week of the David Cup final and comprise a round-robin format followed by a quarterfinal knockout stage.
