NBA Round up - Magic Morant spurs Grizzlies, Heat gore Bulls

Ja Morant produced a virtuoso 52-point performance as the Memphis Grizzlies defeated the San Antonio Spurs 118-105 in the NBA's Western Conference clash on Monday.

Morant made 22 of 30 shots from the field in a magical display for Memphis, two days after scoring 46 points in a win over Chicago.

Morant's career-high masterpiece included two dazzling season highlights -- an astonishing dunk over the Spurs' Austrian player Jakob Poeltl.

He then topped that on the stroke of halftime with a gravity-defying fadeaway jump shot after plucking a length-of-the-court pass from Steven Adams out of the air.

The win leaves Memphis in third in the Western Conference with 43 wins and 20 defeats, trailing the Golden State Warriors (43-18) and the leading Phoenix Suns (49-12).

Elsewhere on Monday, the Miami Heat shut down DeMar DeRozan to rout the Chicago Bulls 112-99 in their top-of-the-table Eastern Conference clash.

Gabe Vincent and Tyler Herro scored 20 points apiece while Jimmy Butler and Bam Adebayo each had 15 points as Miami's balanced offense completed a convincing victory.

But Miami's hard-nosed defensive display also played a huge role in the win, with the Heat ending DeRozan's remarkable run of 10 consecutive games with 30 points or more.

DeRozan was held to 18 points and was never allowed to settle into his rhythm by a rampant Miami, who improved to 41-21 at the top of the conference standings. The Bulls remain in second at 39-23.

"We set multiple things for him – we blitzed him, we tried to give him everything we had and make him uncomfortable," Vincent said of Miami's defense of DeRozan.

"He made some shots despite it, but we came out with the win."

The emphatic win kicks off a challenging run of games for Miami, who play the NBA
