Miami, Florida - The Miami Heat's slide continued on Saturday, with a disappointing 110-95 home defeat against the Brooklyn Nets making it four losses on the trot.

Miami entered the week multiple games clear of the chasing pack, but after the loss against the Nets, the Philadelphia 76ers usurped the Heat as the top seed in the NBA's Eastern Conference.

The race for home-court advantage throughout the Eastern playoffs is far from over, as the top four teams, including the Milwaukee Bucks and the Boston Celtics, are only separated by a half-game.

Things were ugly early for the Heat, with its once-feared defense giving up 40 points in just the second quarter to hand the Nets a 67-46 half-time lead, which was never threatened.

Kevin Durant led a balanced offensive performance from the Nets, finishing with a team-high 23 points on seven-of-14 shooting, while seven of his teammates scored at least eight points each.

The win was Brooklyn's seventh from their past nine games, with Kyrie Irving set to make his home debut the next time out against the Charlotte Hornets.

The Memphis Grizzlies passed another real test when the Milwaukee Bucks came to town, sending the reigning champions home with their tails between their legs after a 127-102 result.

In one of the more unlikely storylines of this season, the Grizzlies are now 17-2 in games where their best player and MVP candidate Ja Morant has not played.

Emerging franchise centerpiece Desmond Bane rose to the occasion, scoring 20 points to go with five assists, while Defensive Player of the Year candidate Jaren Jackson Jr blocked two shots and snatched one steal to go with his 16 points and six rebounds.

With De'Aaron Fox missing yet again, Sacramento Kings rookie Davion Mitchell had his third consecutive game with at least 22 points and seven assists in his side's 114-110 overtime win against the Orlando Magic.

Mitchell's line of 22 points with seven rebounds and nine assists comes after games of 25 points and seven assists against the Indiana Pacers, and 28 points with nine assists against the Phoenix Suns.

Meanwhile, after entering the game with a sputtering record of 3-10 in their past 13 games, the Chicago Bulls collected a much-needed 98-94 win against the Cleveland Cavaliers.

Since February 12, Chicago have only beaten two teams who currently occupy playoff spots – the Cavaliers and the Toronto Raptors.
