It might be the opening weekend of March Madness, but there's still plenty of NBA action on the schedule. 

Starting off the day, Kemba Walker and the Hornets staged an incredible 18-point comeback in the fourth quarter to shock the Celtics, who have now lost three games in a row.

Also early on, the Heat snuck past the Wizards to pick up a big win in their hunt for a playoff spot. Meanwhile, Trae Young's buzzer beater lifted the Hawks over the Sixers in an exciting contest. 

Later on, the Jazz absolutely crushed the lowly Bulls, Karl-Anthony Towns went off to lead the Timberwolves past the Grizzlies and Luka Doncic recorded his sixth triple-double of the season as the Mavericks beat the Warriors by 35 points. 

To close out the night, Damian Lillard led the Trail Blazers to a comeback win over the Pistons, while the Kings closed out the Suns.

Kemba outduels Kyrie in Charlotte

Kemba Walker and the Hornets were struggling on Saturday evening and looked to be heading towards another bad loss. That is, until Walker absolutely took over down the stretch. He led the Hornets on a 30-5 run over the last eight minutes to secure a vital victory to keep their thin playoff hopes alive. Walker scored 18 of his 36 points in the fourth quarter and added 11 rebounds and nine assists. On the other side, Kyrie Irving finished with 31 points, seven rebounds and six assists.

Young beats the buzzer to lead the Hawks to victory

The Atlanta Hawks are not making the NBA playoffs this season but Trae Young is looking more and more like a great selection for the franchise and he proved that once again tonight by hitting the game-winner against the Philadelphia 76ers.

Luka records another triple-double

This might be Dirk Nowitzki's last game in Oakland, but Luka Doncic stole the show. The rookie finished with his sixth triple-double, registering 23 points, 11 rebounds and 10 assists. 

Lillard leads Trail Blazers' comeback win

The Trail Blazers got a crucial win in terms of playoff seeding in the West, and did so thanks to some clutch play from Damian Lillard down the stretch. They closed on a 12-0 run that included a number of big plays by Lillard, including a four-point play to give them the lead for good.

Wade's big night gets Heat a crucial win

Every game is a must-win for the Heat at this point as they try to hold on to the eighth and final playoff spot in the East. On Saturday night in D.C. they did indeed get a win, sneaking past the Wizards in a close one, 113-108. And they did so thanks to Dwyane Wade, who finished with 20 points, nine rebounds and five assists in his last game in D.C. 

Towns puts up monster night in win over Grizzlies

The Timberwolves have already been eliminated from the playoffs, but Karl-Anthony Towns isn't giving up on the season. The big man put up a monster effort on Saturday night, finishing with 33 points and 23 rebounds. It was his second 20-20 game in his last three outings, and seventh double-double in a row.

Jazz put style into the fastbreak

The Jazz got out to a huge lead on the Bulls thanks to sequences like this one. First, they wiped out a shot, then advanced the ball up the court in style before Donovan Mitchell slammed it home with authority.

Boban from deep

Boban Marjanovic now has more 3-pointers than Ben Simmons. The Sixers big man drained a triple from the corner against the Hawks for the first 3 of his career.

Bridges gets it done on both ends

Miles Bridges got busy on both ends against the Celtics. First, he played some nice defense to get a deflection, then hustled down the other end of the floor and finished the fastbreak with an alley-oop.
