A streaking Mike Conley led the fast break and passed the ball off to Ed Davis for a probable layup.

But Davis aborted his shot, flipped the ball by a defender and found Jon Leuer with a nifty pass. Leuer threw down an uncontested dunk, further energizing a crowd that already had been enthralled by the Grizzlies’ bench play.

Conley amassed game highs with 20 points and seven assists. But a group of unusual suspects overwhelmed the Charlotte Bobcats, and led the Griz to a 94-75 victory Tuesday night before 16,591 in FedExForum.

Credit the Grizzlies’ sudden vigor on defense. The Bobcats experienced a major drought in the fourth quarter.

And Leuer couldn’t miss. The little-used Griz forward made all four shots he took, and finished with 11 points and five rebounds. His play epitomized the spark Memphis got from its bench.

“That’s what our job is coming off the bench, just to stay ready and provide energy,” Leuer said. “We came out and really did that. We had great energy, shared the ball and we were getting stops.”

Charlotte guard Jannero Pargo began the fourth quarter with a 3-pointer.

It was all Memphis after that.

Leuer’s slam capped a 15-0 run and put the Griz ahead 78-60 with 7:53 left to play. Memphis led by as many as 25 points in the final frame.

The Griz forced the Bobcats into nine consecutive missed shots, and mostly allowed just one attempt per possession. Offensively, the Griz played fast and free with a lineup that featured Conley, Davis, Leuer, Austin Daye and Quincy Pondexter.

Daye added seven of his 10 points and grabbed six rebounds in the fourth. The reserves scored 27 of the Grizzlies’ 31 points in the period. They turned a three-point game into a rout.

“It wasn’t like we planned it,” Griz coach Lionel Hollins said. “I kept looking for people who had energy. I just felt we weren’t scoring, running and we weren’t really executing. We weren’t playing with the pizzazz we needed so I went with a whole different group.”
