With their 120-114 loss to the Warriors at Oracle Arena, Cleveland fell to 19-61, clinching a top-three worst finish in the league and therefore a share of the best odds to win the No. 1 pick in the 2019 NBA Draft.
The New York Knicks also lost, 129-96 to the Houston Rockets, Friday night to clinch the worst record in the NBA. They are 15-64 with three games to play.
The Phoenix Suns matched the Cavs in the standings with a 133-126 victory over the New Orleans Pelicans Friday.
All three teams will hold a 14-percent chance to win the NBA Draft Lottery in May under new lottery rules that take effect this year.
The lowest the Knicks can pick is fifth in the draft, the second-worst team sixth and third-worst team seventh.
Cleveland won the NBA Draft Lottery in 2003 (LeBron James), 2011 via the LA Clippers (Kyrie Irving), 2013 (Anthony Bennett) and 2014 (Andrew Wiggins).
