MEMPHIS, Tenn. (AP) — Ja Morant threw down a massive dunk over 7-footer Jakob Poeltl and scored a career-high 52 points, lifting the Memphis Grizzlies over the San Antonio Spurs 118-105 Monday night.

The arena was still buzzing from Morant's fast-break slam late in the second quarter when Steven Adams delivered a length-of-the-court pass to Morant, who knocked down a buzzer-beater from the left baseline for a 68-58 halftime lead.

Morant added 13 consecutive points during the fourth quarter to break the game open, following up a career-best 46 points in a win Saturday at Chicago by connecting on 22 of 30 from the field. He hit all four 3-point tries as Memphis won its second straight.

De’Anthony Melton added 15 points for Memphis, while Tyus Jones scored 13.

Morant’s performance was the first 50-point game in Grizzlies franchise history.

Lonnie Walker IV led the Spurs with 22 points, and Dejounte Murray added 21 points and eight assists before being ejected late in the fourth quarter. Poeltl finished with 16 points and 10 rebounds.

The Spurs loss left coach Gregg Popovich one game short of tying Don Nelson for the most regular-season wins by an NBA coach.

The Grizzlies built the lead to 13 early in the fourth, their largest of the game at that point, but the Spurs were within 104-99 near the midway point of the fourth. That’s when Morant scored 13 straight.

Morant had 29 points in the first half on 12-of-15 shooting.
