DALLAS (AP) Who needs timeouts when you have Z-Bo.
Zach Randolph scored 22 points, including several high-arcing jumpers over defensive stalwart Tyson Chandler in the second half to answer Dallas scoring spurts, and Memphis handed the Mavericks their first three-game losing streak of the season with a 109-90 win Tuesday night.
''We only had to call one timeout to stop a run,'' Grizzlies coach Dave Joerger said. ''We executed, and you can't say enough about what Zach got going in the second half.''
The Mavericks had trailed by as many as 16 points but were within nine late in the third quarter when Randolph had the ball on the right wing late in the shot clock.
He hit a 20-footer over Chandler, and the Grizzlies led by double digits the rest of the way to win their fourth straight and eighth in their past nine games a night after finishing a season-long five-game homestand. The only loss in that stretch was to Dallas last week at home.
''That ball was dropping,'' said Randolph, who made seven straight shots in the second half and was 10 of 15 from the field. ''My teammates kept coming to me and believing in me, and I just kept getting aggressive.''
Chandler Parsons and Monta Ellis scored 19 apiece to lead the Mavericks, who failed for the third time to get coach Rick Carlisle his 600th career victory in the first of four games in five nights - the first three against playoff contenders.
''We've got to sustain effort during defensive possessions,'' said Carlisle, whose team fell 3 1/2 games behind Southwest Division-leading Memphis. ''Right now it's a hard conference. It's a hard stretch of schedule.''
Marc Gasol added 15 points and a game-high six assists for the Grizzlies, while Nick Calathes had season highs with 13 points and 27 minutes with guard Mike Conley sidelined a night after spraining his left wrist in a win over Orlando.
The Mavericks fell behind 54-44 at halftime thanks to 14 turnovers, including a steal in the backcourt and layup by Calathes right after he made two free throws to give the Grizzlies four points in the last 5 seconds of the first quarter.
The Grizzlies didn't trail again after Calathes hit a 3-pointer early in the second. Two minutes later, Jordan Adams scored all five of his points to start a 9-0 run that broke a 36-36 tie.
Grizzlies: G Tony Allen missed his second straight game a left ankle sprain. ... Vince Carter scored 12 points in his first visit to Dallas since signing with Memphis as a free agent in the offseason. Carter, who spent three seasons with the Mavericks, got a warm ovation when he came off the bench late in the first quarter.
Mavericks: Ellis got a technical foul for arguing after he was called for charging late in the first half. Carter made the free throw to give Memphis its first double-digit lead at 52-42. ... Before Tuesday, Parsons was limited to one rebound in consecutive games for the first time since his rookie year in 2011-12. He had two against the Grizzlies.
Randolph also had 10 rebounds for his 15th double-double in the past 16 games. He's had 10 straight since returning from a nine-game absence because of a sore right knee. His latest came a night after he and Gasol won their 30th game in which they both had double figures in points and rebounds. That's tops in the NBA, one better than Blake Griffin and DeAndre Jordan of the Clippers.
Calathes' best - and busiest - game of the season came against Parsons, his former high school and college teammate in Florida. They made the high school final four three times and won a Class 5A state title at Lake Howell. They played two seasons together at Florida before Calathes left to play in Greece. His draft rights were traded from Dallas to Memphis in 2013.
Grizzlies: Home against Denver on Thursday.
Mavericks: At Houston on Wednesday.
