Jarrett Jack was the hero for the Brooklyn Nets, making a jump shot with 1.1 seconds remaining to lift the hosts past the NBA-leading Golden State Warriors 110-108.
Momentum was with the Warriors (46-12) at Barclays Center after All-Star guard Stephen Curry sank a trio of three pointers to help the road team erase a 10-point deficit and level the scores at 108-108 with just over a minute left on the clock.
But with the game tied, the Nets (25-33) pounced on Andrew Bogut's loose pass as Jack went up the other end and shot the tiebreaking jumper to give the Brooklyn franchise back-to-back wins.
Jack finished with nine points and five assists off the bench, while Brook Lopez (26) and Deron Williams (22) combined for 48 points for the Nets.
Curry, who inspired the Warriors' successful rally at the Boston Celtics on Sunday, posted 26 points.
The Toronto Raptors snapped their five-game losing streak via a 114-103 win over the lowly Philadelphia 76ers.
Toronto went into the game on the back of defeats to the New York Knicks, Warriors, Dallas Mavericks, New Orleans Pelicans and Houston Rockets since defeating the Atlanta Hawks on February 20.
But the Eastern Conference Atlantic Division leaders, who improved to a 38-22 win-loss record, returned to winning ways thanks to a season-high performance from DeMar DeRozan.
DeRozan was 12 of 24 from the field for 35 points, while Louis Williams chipped in with 21 points of his own.
The 76ers (13-47) were led by Ish Smith and his 19 points off the bench.
Chris Paul had a double-double as the Los Angeles Clippers saw off the Minnesota Timberwolves 110-105.
Paul scored 26 points and dished off 14 assists to lead the Clippers (40-21) to their seventh win in nine games.
Ricky Rubio's (18 points, 12 rebounds, 11 assists) fourth career triple-double was not enough for Timberwolves (13-46) on a night that saw 1,000 fans treated to free tickets thanks to franchise icon Kevin Garnett.
Elsewhere, the Mavericks downed the Pelicans 102-93 courtesy of Monta Ellis and Rajon Rondo, while the Miami Heat accounted for the Phoenix Suns 115-98.
