AUBURN HILLS, Mich. (AP) -- One night after the Pistons gave up 50 points to Atlanta's Shareef Abdur-Rahim, their defense was much better. It had to be. Cliff Robinson scored 23 points as the Pistons, playing without Jerry Stackhouse and Corliss Williamson, rallied past the Memphis Grizzlies 91-84 Saturday night. "The defense waned last night. It came back to life tonight," Detroit coach Rick Carlisle said. "... I liked the competitive effort." After trailing by five points at the end of the third quarter, Detroit scored 17 of the first 21 points in the fourth to build an 83-75 lead. "We just didn't score for the first five to six minutes. We stopped moving the ball around. We held the ball and tried to go one on one," Memphis coach Sidney Lowe said. "Obviously they (the Pistons) did a nice job. They kept posting up Cliff (Robinson) and I think we got confused and fouled them." Robinson also had three blocked shots, five rebounds and four assists. The Pistons forced 20 turnovers, leading to 22 points, and Ben Wallace added to his league-leading total with four blocked shots and 11 rebounds. Jason Williams led the Grizzlies with 25 points while Shane Battier added 18. "It's a thrill and a great feeling that everyone could share my homecoming," said Battier, who played high school ball in Detroit. "I look at this as an opportunity. This franchise has struggled and I'm trying to help turn it around." The Pistons shot 54 percent from the field in the first half and took a 49-44 halftime lead. The Grizzlies scored seven of the last eight points of the quarter to take a 71-66 lead at the end of three as the Pistons seemed out of sync at both ends. Stackhouse missed his second straight game with a strained left groin and is listed as probable for Monday's game in Orlando. Williamson missed Saturday's game with a left hip flexor injury suffered in the loss to Atlanta Friday night. Game notes Carlisle said he was playing a hunch by putting Chucky Atkins back in the rotation ahead of Damon Jones. "I just felt it was the right move. I couldn't give you an exact reason why. It was just a situation where a guy (Jones) deserved an opportunity. Both guys conducted themselves admirably." ... Grant Long was tossed at the 6:09 mark of the third by Derrick Stafford after arguing a call.
