"From there, we dominated the game," coach Lionel Hollins said. "We were in complete control."
Brandon Knight and Jonas Jerebko each scored 13 points and Jose Calderon added 10 points and seven assists for the Pistons, who have lost two of their last three at home.
The Grizzlies trailed by as many as 11 points in the first half, but ended it on a 23-3 run to lead 53-42 at intermission. The Pistons managed just one basket in the final eight minutes of the half and had twice as many turnovers as field goals (8-4) in the second quarter.
Memphis outscored the Pistons 31-12 in the period and never looked back.
Quincy Pondexter, who was whistled for a technical foul midway through the period, had all eight first-half points during the decisive run. He and Tony Allen each finished with 10 points and were a big part of the second-quarter surge.
"We were a little rusty," Allen said after the Grizzlies' first game in six days. "Once we got our composure we were able to do what we do best. We played great defense and pounded the ball inside."
Detroit's energy seemed to disappear in the second half. The lead passed the 20-point plateau after a 13-0 Memphis run midway through the third quarter and stayed there until the final minutes.
"Once we lost the lead they became the instigators and aggressors," Pistons coach Lawrence Frank said. "To me, Tony Allen and Quincy Pondexter changed the game."
Ed Davis came off the bench to score 14 points and Jerryd Bayless had 10 assists for the Grizzlies, who broke a two-game skid away from home.
Tayshaun Prince played his first game at the Palace of Auburn Hills since a Jan. 30 trade sent him and Austin Day to Memphis. The starter on Detroit's 2004 NBA championship team drew a loud ovation from the crowd of 13,481.
