Eight days after letting a win slip away against the Warriors, the Celtics were able to finish the job against another tough Western Conference opponent.

Kyrie Irving had 30 points and 11 assists to help the Celtics overcome big games from Paul George and Russell Westbrook and snap the Thunder’s seven-game winning streak in a 134-129 thriller on Sunday in Boston.

The Celtics have won four straight since a 115-111 home loss to the Warriors on Jan. 26 and nine of 10 overall.

“(This is) a good win,” said Al Horford, who had 17 points and nine assists. “This team has been playing really well, and it’s just good to get this win here at home.”

George scored 37 points and Russell Westbrook notched his sixth straight triple-double and 19th of the season with 22 points, 16 assists and 12 rebounds.

“We just played a good team,” George said. “I thought they made some big plays, big shots. Gotta live with it.”

Mike Conley scored 25 points, Marc Gasol had 24 and the Grizzlies snapped a nine-game road losing streak with a 96-84 victory over the Knicks. AP
