Karl-Anthony Towns made a go-ahead 3-pointer with 46.6 seconds left and finished with 27 points, Jalen Brunson had 32 points and 11 assists and the Knicks beat the Pistons 94-93 on Sunday in Detroit to take a 3-1 lead in their first-round NBA Eastern Conference playoff series.

The Pistons’ Cade Cunningham had 25 points, 10 assists and 10 rebounds for his first playoff triple-double but missed two shots and turned the ball over in the final 1:07.

Tim Hardaway Jr. shot a 3-pointer just before the buzzer and drew some light contact from the Knicks’ Josh Hart that wasn’t called a foul at the end of a physical game with few whistles from the officials.

The Pistons have lost nine straight home playoff games since 2008, equaling an NBA record set by the 76ers from 1968 to 1971.

The third-seeded Knicks expected the sixth-seeded Pistons’ best punch, then came out swinging.

Towns scored in the post and had a block, OG Anunoby had a block in the opening minute and the Knicks went on a 14-2 run to take a 10-point lead midway through the first quarter.

The Knicks’ smothering defense forced six turnovers and scored 10 points off them to take a 29-19 lead after the first quarter.

The Knicks led by as much as 16 points in the second quarter before the Pistons went on an 11-0 run to help them pull within seven at halftime.

In the third, when the Pistons outscored the Knicks 28-14 to take a seven-point lead, Cunningham was the best player on the court.

He had 12 points — making 6 of 7 shots — five assists, five rebounds and three blocks.

The Knicks had a scare late in the third when Brunson limped off the court and toward the locker room with an apparent right knee injury, but he returned to form in the fourth.

Thunder advance: Shai Gilgeous-Alexander scored 38 points and the Thunder advanced to the Western Conference semifinals Saturday by beating the host Grizzlies 117-115 to complete a four-game sweep.

The eighth-seeded Grizzlies played without star guard Ja Morant, who bruised his hip in Game 3.

Dunk does it for Nuggets: Aaron Gordon slammed down Nikola Jokic’s miss as time expired to lift the fourth-seeded Nuggets over the fifth-seeded Clippers 101-99 on Saturday night, to tie their West series 2-2.

Video review confirmed the ball left Gordon’s hands above the rim just before the buzzer sounded after the visiting Nuggets had blown a 22-point lead.
