The Boston Celtics won the NBA Draft lottery on Tuesday, capitalizing on a trade they made with the Brooklyn Nets four years ago.

The Los Angeles Lakers were other big winners, moving up one spot to second to hold onto their pick. They would have had to trade it to Philadelphia if it fell outside the top three.

The Celtics will go from No 1 seed to No 1 pick after their 25 percent chance of winning came through on Tuesday night.

Boston opens the Eastern Conference final at home on Wednesday against Cleveland.

Brooklyn finished with the worst record in the league but the Celtics had the right to swap picks with the Nets from the 2013 draft-night trade that sent Kevin Garnett and Paul Pierce to the Nets.

The 76ers will pick third, while Phoenix fell two spots and is fourth.

The Celtics were going to be in prime position no matter how the ping-pong balls bounced.

They were guaranteed no worse than the No 4 pick to add to a team that had the best record in the East this season. And they still get one more first-round pick next season from the Nets, who likely will miss the playoffs again.

Boston acquired the Nets' 2014, 2016 and 2018 first-round picks in the deal.

Their victory made it three straight years the team with the best odds has won the lottery, after going the previous decade without a victory.

Minnesota snapped that streak by getting eventual Rookie of the Year Karl-Anthony Towns in 2015 and Philadelphia took Ben Simmons last season.

The upcoming draft is considered a deep one, loaded with point guards such as Markelle Fultz, Lonzo Ball and De'Aaron Fox.

And the Lakers will get a chance to take one of them after beating the odds to move up in their first year with Hall of Famer Magic Johnson as their team president. They had about a 53 percent chance of falling out of the top three, which would have triggered a trade of the pick as remaining payment of their acquisition of Steve Nash in 2012.

Not only that, but they would have had to trade their 2019 first-round pick to Orlando if that happened, so Johnson was all smiles even after finishing behind the rival Celtics.

Sacramento moved into the top three, but the 76ers had the right to swap with them through terms of a past trade.
