The Pistons shot 6 of 7 on 3-pointers in the final period and defeated the playoff-bound Memphis Grizzlies 103-90 Sunday night.
"We were playing hard," Pistons coach Stan Van Gundy said. "The ball just has to go in, and we finally started making some shots. The game looks a lot different when the ball starts going in the basket."
Reggie Bullock and Boban Marjanovic each scored 14 points to lead the Pistons. Marjanovic also had 10 rebounds.
While the latter stages of the third quarter got the Pistons jumpstarted, the shooting was the key to the fourth. Detroit, which trailed by 12 early in the third period, using the shooting from outside the arc to pull away from Memphis, which played its reserves in the fourth with the seventh seed in the Western Conference secured.
"The third quarter, we made that run against their main guys," Van Gundy said. "That was impressive. Then, obviously (Memphis coach David Fizdale) shut it down, and we played against younger guys."
Darrun Hilliard scored 11 of his 13 points in the fourth, and Tobias Harris finished with 12 despite not playing in the final frame as Van Gundy, like Fizdale, relied on his bench down the stretch.
Mike Conley led Memphis with 15 points, while Marc Gasol added 13 and JaMychal Green had 12. In addition to sitting his starters in the final quarter, Fizdale also gave reserve forward Zach Randolph the night off for "rest."
"We knew coming into the game, even if we played our guys at full minutes, the Pistons are no pushovers," Fizdale said.
Memphis, as it did against the New York Knicks two nights earlier, struggled to control the game after building its 12-point lead immediately after halftime.
The Grizzlies fumbled their way to eight turnovers in the first nine minutes of the third quarter, allowing the Pistons to get within one possession several times. Detroit couldn't capitalize initially because it committed a half-dozen over the same span.
But Bullock's 3-pointer gave Detroit a 66-65 lead. That came as Memphis went more than four minutes without scoring.
The anemic Memphis performance allowed Detroit to outscore the Grizzlies 27-10 in the third and carry a 75-67 lead into the fourth.
And the Grizzlies never retook the lead the rest of the way.
"I thought the way we closed out as a team was real big," said Henry Ellenson, who converted a pair of 3-pointers in the fourth.
