No one had epitomized the Grizzlies’ depressed state over the past week more than Zach Randolph.

The veteran forward was mired in a funk that coincided with the team’s suddenly weakened defense. But Randolph used the paint to rediscover his power game early Friday night, and the Grizzlies complemented his effort by nearly grinding the run-and-gun Houston Rockets to a halt.

The result was a 103-94 victory for the Grizzlies, who enjoyed Randolph’s resurgence, a defensive revival and their 11th straight win in FedExForum.

“It’s a long season. Even M.J. (Michael Jordan) had bad games. It’s just part of it,” said Randolph, who finished with 21 points and 12 rebounds to end a five-game stretch in which he shot 38 percent and turned the ball over at a high rate.

“We didn’t even talk about it. I just tried to come out and be myself. I wanted to get deep post position and attack the basket. I just wanted to be aggressive.”

Randolph provided the necessary muscle for the Griz to get off to a strong start. And there appeared to be a concerted effort to make sure Randolph got the ball early.
