The Brooklyn Nets upstaged the Los Angeles Clippers 129-120, despite Kawhi Leonard's big performance in the NBA on Sunday.
Leonard posted a game-high 39 points for the Clippers but it was not enough against the Nets in Orlando, Florida.
Caris LeVert put up 27 points and 13 assists as the Nets clinched the seventh seed in the Eastern Conference.
Joe Harris added 25 points of his own for the Nets at Walt Disney World Resort, where team-mate Jarrett Allen (16 points, 16 rebounds) finished with a double-double.
Damian Lillard, meanwhile, dropped 51 points to inspire the Portland Trail Blazers to a 124-121 win over the Philadelphia 76ers.
Lillard made 16 of 28 shots and 15 from 16 free throws to lift the Trail Blazers past the 76ers and within a half-game of the Memphis Grizzlies for eighth place in the Western Conference.
It was Lillard's fifth game of 50-plus points this season – tying Houston Rockets star James Harden – with all of those performances coming against teams that made the playoffs last year
Per STATS, the last player to have five 50-point games against postseason teams from the previous campaign was Michael Jordan (6) in 1986-87.
Career-high night for Rivers
Austin Rivers had a game to remember as the Rockets soared past the Sacramento Kings 129-112. The Rockets guard registered a career-high 41 points off the bench. Rivers is the first player in NBA history to score 40-plus points, make six or more three-pointers and shoot 70.0-plus per cent from the field off the bench in a game, per STATS. Harden contributed 32 points, eight rebounds and seven assists for the Rockets.
Gordon Hayward's 31-point display helped the Boston Celtics top the Orlando Magic 122-119 in overtime. Jayson Tatum scored 29, including the tying basket with 4.2 seconds remaining in regulation.
Defending champions the Toronto Raptors secured the Eastern Conference second seed and their fifth consecutive season with at least 50 wins after outlasting the Grizzlies. Pascal Siakam had 26 points.
The San Antonio Spurs and their hopes of becoming the first team in NBA history to reach the playoffs for 23 straight seasons remain alive after emerging 122-113 winners against the New Orleans Pelicans. San Antonio are 10th in the west, half a game adrift of Portland for the ninth spot, which would secure a play-in series.
Pelicans eliminated from postseason race, Wizards winless in bubble
Zion Williamson will have to wait another year for playoff basketball after the Pelicans lost to the Spurs. Despite 31 points and a season-high eight three-pointers from JJ Redick, the Pelicans – coupled with Portland's win – were eliminated from postseason contention.
The Washington Wizards' woes continued after falling to a 121-103 defeat against the Oklahoma City Thunder. Washington are the only winless team remaining in Orlando, having gone 0-6 since the restart.
Dame with the four-point play!
After struggling against the Clippers, Lillard came up big for the Trail Blazers in their meeting with the 76ers. A spectacular four-point play with less than three minutes remaining catapulted the Blazers into the lead.
