Randolph had been limited to just 19.8 points and 31.9 percent shooting since his career playoff-best scoring output in Game 1. He had been the focus of the Thunder's defense and had just nine points on 3 of 9 shooting in Game 5. Hollins credited the difference to having 48 more hours to recover from their triple-overtime loss Monday.
The power forward, named to the All-NBA's third team on Friday, scored 12 in the fourth to preserve Memphis' lead. Randolph scored six straight points, capped by a 12-foot fallaway jumper that sent the fans into a frenzy chanting his nickname.
"He was making jump shots, and he was making contested jump shots," Thunder coach Scott Brooks said. "He's third-team All-NBA for a reason. That guy is a player, and when he gets it going, you only can do what you can do and that is contest his shot and force him to take tough shots and he made some tough shots tonight."
Mayo, told by Hollins he would start before the morning shootaround, called Randolph's play unbelievable.
"He never fails," Mayo said. "You can live when he has a bad game because he plays so many incredible games, and down the stretch he carries us so much that when he has a bad game, you're like 'OK, he's a little human.' But pretty much, he never fails us."
One sequence late summed up the Thunder's offensive woes. The Thunder had a fast break with Westbrook driving to the basket, but he just couldn't finish the shot. Randolph came up with the rebound, then Mayo hit a 19-footer to push the Grizzlies' lead to 88-79 with 3:11 left.
The Thunder had their biggest lead at 54-41 just before halftime and looked ready to blow out Memphis, just as they did in Game 5 on Wednesday night in Oklahoma City.
But Shane Battier ended the first half with a 3-pointer, and the Grizzlies used that as the start of an 18-5 run into the third. Randolph's bucket with 5:19 left in the third tied it at 59, Gasol tied it again at 65, and Mayo's three-point play put Memphis ahead to stay at 68-65 with 2:10 left.
NOTES: Young had a tough day Friday. He found his car had been stolen after the morning shootaround. It was retrieved 15 minutes or so later, and he credited OnStar for the recovery. ... The Denver Nuggets won six postseason games as a No. 8 seed in 1994. ... Mayo also had four steals and four assists. ... The Thunder hit 11 of 20 in the second quarter when they outscored Memphis 30-21.
