"It was not intimidating," Mayo said of the defense and returning to Memphis. "It was just a little different obviously. They know my tendencies. It was pretty much O.J. was not getting anything, and (we) had to get other guys to make some plays."
Neither team shot particularly well in the first half — Dallas connecting on 34 percent, while Memphis was shooting at a 38 percent clip. Memphis missed all five of its shots from beyond the arc, and Dallas was stymied by 13 turnovers, while the Grizzlies had eight miscues.
Both teams would end the night shooting just better than 40 percent.
Mayo eventually hit his first field goal with 4:26 left in the third. Dallas had tied it at 49 with just over 9 minutes left in the third, but Memphis responded with 14 straight points, grabbing the first double-digit lead of the game.
The lead eventually would reach 17 and Memphis carried a 69-57 advantage into the fourth.
Dallas pushed its offense, again with the reserves helping bring the energy to open the final frame. It translated to a 14-2 run spanning the third and fourth periods as the Mavericks went with a smaller lineup in hope of offsetting the Grizzlies inside presence.
"We just couldn't get over the hump," Marion said. "We were out there scratching and clawing, climbing he hill, but we couldn't get over. Sometimes it happens like that."
The Mavericks kept pushing their offense spreading out the scoring to pull to 76-73 near the midway point of the fourth.
Gay and Randolph converted a pair of 3-point plays to stretch the lead back to 82-73. Then a dunk by Gay took the lead to double digits.
The Mavericks would pull within five points, but could get no closer the rest of the way, losing their fifth in the last six.
As for his defensive effort, Allen said with the rest of the Grizzlies starters, it's his niche in the Memphis lineup.
"You've got to look at it like this: sitting next to Rudy Gay, Mike Conley, Zach Randolph and Marc Gasol, they're going to fill up the scoring," Allen said. "I've just got to be that glue guy who (does) the intangibles. Who do the things that are not expected from those guys. That's my role, and I want to fulfill it to the best of the ability I can."
NOTES: Mayo was not the only returning former Grizzly returning to Memphis. Like Mayo, Mavs F Dahntay Jones played his first four years in the league for the Grizzlies. ... Brandan Wright, who missed Thursday's game against Miami with a sprained right ankle, returned to action against Memphis. Elton Brand missed his third straight game with a right groin strain for Dallas. ... Dallas' Darren Collison left the game with an "illness" according the injury report. He didn't return.
