"What an unbelievable night by Ja," Memphis coach Taylor Jenkins said. "When he got going it kind of fueled everyone else. We’ve said it from Day 1, he’s built for moments like this."
Jenkins also was impressed with Morant’s defense (two steals, two blocks) and rebounding. He had 10 rebounds.
"I was taking what the defense gave me and it turned out good for us," Morant said. "That’s normally how I attack every game. Tonight was just my night."
Memphis trailed in the second half until Tyus Jones hit in a floater for a 93-92 lead with 6:50 left. Morant followed with consecutive 3-pointers for a 99-92 advantage with 4:28 to go. Bane sealed the win with two free throws with 5.1 seconds to go

The Grizzlies were able to battle back and trim the lead to five at 83-78 at the end of the quarter. Morant made in a deep 3-pointer at the buzzer.
In the fourth quarter, the Lakers were slowed by four-minute scoring drought which allowed the Grizzlies to erase a 92-87 deficit with 12 straight points. With 8:12 to go, Memphis led 99-92
"Coming out in the third quarter it got away from us," Lakers forward Malik Monk said. "It was super frustrating because we’ve been doing that all year."
