Jayson Tatum scored 33 points as the Boston Celtics overturned a double-digit deficit to extend their lead at the top of the NBA Eastern Conference on Saturday with a 122-106 road victory over the lowly Charlotte Hornets.

But Boston were startled by a confident first-half performance from Charlotte, who surged to a 16-point lead midway through the second quarter.

Boston trimmed the gap to just four points at halftime, with Charlotte leading 66—62, Then the Celtics cut loose in a devastating burst of scoring after the break.

Malcolm Brogdon had 30 points for Boston, while Al Horford added 16 and Marcus Smart 13.

LaMelo Ball led the Hornets' challenge with 31 points.

"They were more 'up' to play us, and we came out on our heels," Tatum said. "I'm just glad that we played with more physicality, played tougher. We started hitting some shots, too."

The Memphis Grizzlies bagged their ninth win in a row with a 130-112 blowout of the Indiana Pacers.

The win leaves Memphis level with Denver at the top of the Western Conference with both teams at 29-13.

- Embiid lifts 76ers -

Harden scored 31 points and handed out 11 assists and Embiid scored 30 for the Sixers, who were in control after scoring 41 points in the first quarter for a 17-point lead.

The Jazz had whittled that to three points going into the fourth period, finally taking the lead for the first time on Walker Kessler's tip-in of a Jordan Clarkson miss that made it 115-114 with 33 seconds left.

Harden and Clarkson -- who led Utah with 38 points -- traded baskets that left the Jazz up 117-116 before Embiid struck, and the 76ers' strong defense denied Utah on the final possession.
